Description

Technical Field

[0001] The present invention relates to a nano-composite construction preparation method and system for a highly flexible display film, belonging to the technical field of material preparation. Background Art

[0002] At a time when display technology is developing rapidly, the market demand for highly flexible display films, as key materials in the new display field, is growing explosively. Whether it is foldable electronic devices or wearable display equipment, highly flexible display films have become the core elements driving product innovation with their unique flexibility and excellent display performance. In order to meet the market's increasingly stringent performance requirements for highly flexible display films, it is particularly critical to achieve efficient and precise nano-composite construction and preparation.

[0003] The nanocomposite construction and preparation of traditional highly flexible display films mostly rely on conventional process methods. First, the combination of nanomaterials and display film substrates is determined based on experience, and specific nanomaterials and display film substrate materials are selected. During the preparation process, the nanomaterials are dispersed, coated and compounded according to the established process. With the help of traditional stirring, ultrasonic and other dispersion techniques, the nanomaterials are evenly dispersed in a specific solvent, and then the dispersion is coated on the display film substrate by spin coating, spraying and other methods. Subsequently, the nanomaterials and the substrate are compounded through conventional processes such as heating and pressurization.

[0004] However, this traditional preparation method relies too much on experience and is difficult to accurately match the characteristics of different nanomaterials with the display film substrate, resulting in poor dispersion uniformity of the nanomaterials during the composite process and unstable bonding strength with the substrate. Traditional dispersion and composite processes are extremely sensitive to changes in environmental conditions. Slight fluctuations in temperature and humidity will seriously affect the dispersion state and composite effect of the nanomaterials, resulting in uneven product quality and difficulty in improving the yield rate, which in turn leads to poor preparation quality of highly flexible display films. Therefore, a method is needed to improve the quality stability of the preparation of highly flexible display films. Summary of the Invention

In this embodiment, the method for preparing a nanocomposite structure of a highly flexible display film includes:

[0067] S1. Obtain a nanocomposite material of a highly flexible display film and its corresponding display film application scenario, collect structural parameter information corresponding to the nanocomposite material, and set a composite construction sequence corresponding to the nanocomposite material according to the display film application scenario and the structural parameter information.

[0068] The present invention sets the composite construction sequence corresponding to the nano-composite material according to the application scenario of the display film and the structural parameter information, which can ensure that the composite process is highly adapted to actual needs, and lays an important foundation for the subsequent improvement of the performance and preparation efficiency of the high-flexibility display film. It should be explained that the high-flexibility display film is a new type of display material with high flexibility and good display performance. The nano-composite material is a composite substance composed of nanoscale materials used to enhance the performance of the high-flexibility display film. The application scenario of the display film is the actual use environment of the high-flexibility display film in the fields of foldable electronic devices, wearable display equipment, etc. The structural parameter information is the nano The composite material corresponds to quantitative data reflecting its microstructural characteristics, such as particle size, crystal form, and interlayer spacing. The composite construction sequence is the operation sequence of the composite processing of the nanocomposite material according to specific logic and steps. Furthermore, the nanocomposite material of the highly flexible display film and its corresponding display film application scenarios can be obtained through suppliers and the actual application needs of the product. For example, for foldable mobile phone screens, it is necessary to focus on the requirements for the flexibility and durability of the display film under the requirements of the number of bending times and bending radius; the collection of structural parameter information corresponding to the nanocomposite material can be achieved through collection equipment, such as high-resolution transmission electron microscopes and X-ray diffractometers.

[0069] In detail, setting the composite construction sequence corresponding to the nanocomposite material according to the application scenario of the display film and the structural parameter information includes:

[0070] Performing a demand attribute analysis on the application scenario of the display film to obtain the scenario demand attributes;

[0071] Extracting representation structure information from the structure parameter information, and calculating the degree of fit between the representation structure information and the scene requirement attributes;

[0072] Based on the degree of fit, constructing a fit composite material matrix corresponding to the nanocomposite material;

[0073] performing multi-objective optimization on the conforming composite material matrix to obtain an optimized material matrix;

[0074] Based on the optimized material matrix, a composite construction sequence corresponding to the nanocomposite material is set.

[0075] It should be explained that the scenario requirement attributes are the specific requirements for the high-flexibility display film in the application scenario of the display film in terms of flexibility, number of bends, size requirements, power consumption, safety in contact with the human body, etc.; the characterization structure information is the particle size, crystal form, interlayer spacing, specific surface area, chemical bonding state, etc. in the structural parameter information, which can reflect the key data of the microstructure characteristics of the nanocomposite material and are closely related to the performance of the display film; the degree of fit indicates the degree of conformity between the characterization structure information and the scenario requirement attributes in terms of material performance adaptation, and is used to measure how well the structural characteristics of the nanomaterial meet the application scenario requirements; the The compatible composite material matrix is a data set corresponding to the nano-composite material that integrates various characterizing structural information and presents the adaptation relationship with the scene requirement attributes in the form of a matrix; the optimized material matrix is a better data set obtained after the compatible composite material matrix is optimized through multiple objectives, and each element is adjusted and screened under multiple goals such as improving flexibility, enhancing bonding strength, and optimizing optical properties; the composite construction sequence is the detailed process of the sequence of nanomaterial dispersion, coating, compounding and other operation steps determined according to the scene requirement attributes and the optimized material matrix corresponding to the nano-composite material, as well as the specific parameter setting.

[0076] Furthermore, the demand attributes of the display film application scenarios can be analyzed through market research, user feedback collection and scenario simulation experiments to obtain scenario demand attributes; the characterization structure information in the structural parameter information can be extracted through data mining algorithms; based on the fit, a matching composite material matrix corresponding to the nano-composite material can be constructed through matrix operations; the matching composite material matrix can be multi-objective optimized through genetic algorithms to obtain an optimized material matrix, such as with the goal of improving the flexibility, optical transparency and mechanical strength of the highly flexible display film, through the selection, crossover and mutation operations of the genetic algorithm, under the constraints of a reasonable proportion of nanomaterials and controllable costs, the optimal combination matrix of each parameter is obtained by continuous iterative optimization; based on the optimized material matrix, the composite construction sequence corresponding to the nano-composite material is set in combination with process constraints and empirical knowledge, such as taking into account process constraints such as the working range of the composite equipment, the temperature and pressure tolerance limits, and referring to empirical parameters such as dispersion time and coating speed obtained in previous similar material preparations, the operating steps and parameters such as the dispersion order, coating method, composite temperature, pressure and time of the nanomaterials are determined.

[0077] Furthermore, as an optional embodiment of the present invention, the calculating the degree of compatibility between the representation structure information and the scenario requirement attributes includes:

[0078] quantifying an actual measurement value corresponding to the nanocomposite material based on the characterization structure information;

[0079] Determining a scene constraint threshold corresponding to the actual measurement value based on the scene requirement attribute;

[0080] Combining the actual measurement value and the scene constraint threshold, the degree of fit between the representation structure information and the scene requirement attribute is calculated using the following formula:

[0081]

[0082] Among them, δ represents the degree of fit between the representation structure information and the scene requirement attributes, B a Indicates the ath measurement value in the actual measurement value, D a represents the scene constraint threshold corresponding to the ath measurement value in the actual measurement value, a represents the sequence number of the actual measurement value, and q represents the number of actual measurement values.

[0083] It should be explained that the actual measurement value is a specific value reflecting the microstructural characteristics (such as particle size, specific surface area value, crystal structure parameters, etc.) of the nano-composite material obtained after quantifying the characterizing structural information; the scene constraint threshold is a critical value range set according to the specific requirements and performance standards of the display film application scenario corresponding to the actual measurement value, which measures whether the actual measurement value meets the requirements of the application scenario. When the actual measurement value exceeds the threshold range, it may affect the performance of the highly flexible display film in the corresponding scenario.

[0084] Furthermore, based on the characterization structure information, the actual measurement value corresponding to the nano-composite material can be quantified through a coding algorithm; based on the scenario requirement attributes, the scenario constraint threshold corresponding to the actual measurement value can be comprehensively determined through analysis and research of a large number of application scenario cases, simulation experiments and industry standard specifications.

[0085] S2. Calculate the interfacial coupling bond strength of the nanocomposite material during the composite process, and calculate the deformation adaptation coefficient of the display membrane substrate during the composite process. Combined with the interfacial coupling bond strength and the deformation adaptation coefficient, analyze the dynamic synergistic composite performance of the nanocomposite material.

[0086] The present invention calculates the interfacial coupling bond strength of the nanocomposite material during the composite process, and the interfacial coupling bond strength can be used to understand the degree of bonding strength of the nanocomposite material during the composite process, thereby providing an important basis for the subsequent analysis of the dynamic synergistic composite efficiency of the nanocomposite material. It should be explained that the interfacial coupling bond strength refers to the degree of bonding strength of the nanocomposite material at the composite interface, reflecting the strength of the interaction between the two.

[0087] In detail, the calculation of the interfacial coupling bonding strength of the nanocomposite material during the composite process includes:

[0088] collecting composite samples of the nanocomposite material during the composite process, performing a peeling test on the composite sample, and obtaining a peeling force curve;

[0089] Based on the peel force curve, determining the instantaneous peel force and peel test frequency corresponding to the composite sample;

[0090] Calculating the average peel force of the nanocomposite material during the compounding process by combining the instantaneous peel force and the peel test frequency;

[0091] The test interface width of the composite sample during the peel test is measured, and the interface coupling bonding strength of the nanocomposite material during the composite process is calculated based on the test interface width and the average peel force.

[0092] It should be explained that the composite sample is a physical material sample prepared by the nano-composite material according to certain processes and conditions during the composite process; the peel force curve is a curve of the applied peel force changing with time or displacement recorded by professional testing equipment when the composite sample is subjected to a peel test; the instantaneous peel force and the peel test frequency are respectively the instantaneous peel force measured at a certain moment during the peel test of the composite sample and the number of times the composite sample is subjected to a peel test; the average peel force is a representative value obtained by statistical calculation (such as averaging) of the peel force of the nano-composite material during the composite process; the test interface width is the lateral dimension of the interface used for the peeling operation during the peel test of the composite sample.

[0093] Furthermore, composite samples of the nano-composite material during the composite process can be collected by an automated sample collection device at preset time intervals or process nodes, and the composite samples can be subjected to a peeling test process using a material mechanics testing machine equipped with a special peeling test fixture to obtain a peeling force curve; based on the peeling force curve, the peak detection and counting functions of the data analysis software are used to determine the instantaneous peeling force and peeling test frequency corresponding to the composite sample; the instantaneous peeling forces are summed to obtain the total peeling force, and the total peeling force is divided by the peeling test frequency to obtain the average peeling force of the nano-composite material during the composite process; the test interface width of the composite sample during the peeling test process can be measured using a high-precision laser rangefinder or a digital caliper, and the ratio of the average peeling force to the test interface width is calculated to obtain the interface coupling bonding strength of the nano-composite material during the composite process.

[0094] By calculating the deformation adaptation coefficient of the display membrane substrate during the composite process, the present invention can accurately understand the deformation coordination of the display membrane substrate and the nano-composite material during the composite process, thereby improving the analysis accuracy of the dynamic synergistic composite efficiency of the nano-composite material. It should be explained that the deformation adaptation coefficient indicates the degree of matching between the deformation degree of the display membrane substrate and the deformation degree of the nano-composite material during the composite process, reflecting the ability of the two to adapt to each other and synergistically deform during composite.

[0095] In detail, the calculation of the deformation adaptation coefficient of the display film substrate during the composite process includes:

[0096] Perform three-dimensional scanning on the display film substrate during the composite process to obtain three-dimensional data of the substrate shape, and collect strain data of key positions of the display film substrate during the composite process;

[0097] performing denoising processing on the base shape three-dimensional data to obtain denoised base shape data;

[0098] Combining the key position strain data and the denoised substrate shape data, extracting the true deformation parameters corresponding to the display film substrate;

[0099] The deformation adaptation coefficient of the display film substrate during the composite process is calculated by combining the actual deformation parameter and the preset parameter threshold.

[0100] It should be explained that the three-dimensional base shape data is the digital spatial information obtained by three-dimensional scanning of the display film base during the composite process; the key position strain data is the data on the degree of local stress deformation at multiple key points of the display film base during the composite process; the denoised base shape data is the data obtained after removing the noise generated by scanning errors, environmental interference and other factors from the three-dimensional base shape data; the real deformation parameters are a series of quantitative values corresponding to the display film base calculated based on the denoised base shape data and key position strain data for characterizing the actual deformation characteristics of the base.

[0101] Furthermore, a high-precision three-dimensional laser scanner can be used to perform three-dimensional scanning on the display film substrate during the composite process to obtain three-dimensional data of the substrate shape; a distributed optical fiber strain sensor can be used to collect strain data of key positions of the display film substrate during the composite process; a denoising algorithm based on wavelet transform can be used to denoise the three-dimensional substrate shape data to obtain denoised substrate shape data; and the strain data at key positions and the denoised substrate shape data can be combined to extract the real deformation parameters corresponding to the display film substrate using a method combining finite element analysis and data fitting.

[0102] Furthermore, as an optional embodiment of the present invention, the calculation of the deformation adaptation coefficient of the display film substrate during the composite process by combining the actual deformation parameter and the preset parameter threshold includes:

[0103] Based on the preset parameter threshold, determining the maximum deformation value and the minimum deformation value corresponding to the true deformation parameter;

[0104] Combining the maximum deformation value, the minimum deformation value, and the true deformation parameter, the deformation adaptation coefficient of the display film substrate during the composite process is calculated using the following formula:

[0105]

[0106] Where A represents the deformation adaptation coefficient of the display film substrate during the composite process, E i,real Indicates the value of the i-th parameter in the true deformation parameter, E i,ideal represents the ideal value corresponding to the i-th parameter value, E i,max Indicates the maximum deformation value corresponding to the i-th parameter value, E i,minIt represents the minimum deformation value corresponding to the i-th parameter value, i represents the serial number corresponding to the true deformation parameter, and r represents the number corresponding to the true deformation parameter.

[0107] It should be explained that the ideal value corresponding to the parameter value is determined comprehensively based on the design objectives, performance requirements and industry standards of the high-flexibility display film, and is the optimal value that the parameter should reach under ideal conditions.

[0108] The present invention analyzes the dynamic synergistic composite efficiency of the nanocomposite material by combining the interface coupling bond strength and the deformation adaptation coefficient. This can accurately analyze the degree of synergy between the nanocomposite material and the display film substrate during composite, providing a key reference for optimizing the composite process and improving the comprehensive performance of the highly flexible display film. It should be explained that the dynamic synergistic composite efficiency is the ability of the nanocomposite material to effectively combine and synergize with the display film substrate in a dynamic environment, taking into account factors such as the interface coupling bond strength and the deformation adaptation coefficient during composite, so as to improve the overall performance of the highly flexible display film. Furthermore, the dynamic synergistic composite efficiency of the nanocomposite material is analyzed by combining the interface coupling bond strength and the deformation adaptation coefficient. First, the interface coupling bond strength and the deformation adaptation coefficient are normalized to eliminate the dimensional effect. Then, based on the normalized values, when the interface coupling bond strength value is high and the deformation adaptation coefficient is also high, it indicates that the nanocomposite material is firmly bonded to the display film substrate and has good deformation coordination, and the dynamic synergistic composite efficiency is high; conversely, if either value is low, the dynamic synergistic composite efficiency is low.

[0109] S3. Record the thermal gradient distribution data and pressure load data of the nanocomposite material during the construction process, calculate the stress relaxation rate inside the display film after the construction is completed based on the thermal gradient distribution data, calculate the uniform attenuation coefficient of the interlayer structure of the display film based on the pressure load data, and evaluate the multi-dimensional structural stability performance of the display film by combining the stress relaxation rate and the uniform attenuation coefficient.

[0110] The present invention calculates the stress relaxation rate inside the display film after construction is completed based on the thermal gradient distribution data, so as to understand the attenuation characteristics of the internal stress of the display film over time, and provides an important basis for the subsequent evaluation of the multi-dimensional structural stability performance of the display film. It should be explained that the thermal gradient distribution data is a real-time record of the temperature changes of the nano-composite material at different times and spatial positions during the construction process; the pressure load data is a collection of detailed information on the size, duration and distribution of pressure applied to the material and the molded display film by the nano-composite material during the construction process; the stress relaxation rate represents the rate at which the internal stress of the display film gradually decreases over time after construction is completed, which is used to measure the ability of the display film to relieve internal stress; further, the recording of the thermal gradient distribution data and pressure load data of the nano-composite material during the construction process can be achieved by deploying high-precision temperature sensors and pressure sensors at key parts of the construction equipment, and combining with a data acquisition system to transmit and store the data collected by the sensors in real time to a computer.

[0111] Specifically, the calculation of the stress relaxation rate inside the display film after the construction is completed based on the thermal gradient distribution data includes:

[0112] Performing spatiotemporal discrete sampling on the thermal gradient distribution data to obtain a three-dimensional temperature field matrix;

[0113] Performing fast Fourier transform processing on the three-dimensional temperature field matrix to obtain a frequency domain temperature matrix;

[0114] Calculating the modal energy corresponding to the frequency-domain temperature matrix, and analyzing the dominant thermal mode corresponding to the frequency-domain temperature matrix based on the modal energy;

[0115] Based on the dominant thermal mode, the thermal distribution of the display film after construction is reconstructed to obtain the spatiotemporal stress distribution;

[0116] Based on the spatiotemporal stress distribution, the stress relaxation rate inside the display film after the construction is completed is calculated.

[0117] It should be explained that the three-dimensional temperature field matrix is the result of performing spatiotemporal discrete sampling on the thermal gradient distribution data, discretizing the continuous thermal gradient information in the time and space dimensions, and presenting the temperature data at different times and spatial locations in matrix form. The frequency-domain temperature matrix is the result of performing fast Fourier transform processing on the three-dimensional temperature field matrix, converting the temperature data represented in the space and time domains into the frequency domain, thereby obtaining a matrix form that can reflect the different frequency components of the temperature field. The modal energy is the energy value of each thermal mode corresponding to the frequency-domain temperature matrix, reflecting the contribution of different frequency components to the total energy of the temperature field. The dominant thermal mode is the specific thermal mode corresponding to the frequency-domain temperature matrix that has the maximum modal energy among the numerous thermal modes based on the modal energy analysis and plays a major role and decisive influence on the overall temperature field distribution. The spatiotemporal stress distribution is the result of reconstructing the thermal stress distribution of the display film at different times and spatial locations based on the main temperature field change characteristics reflected by the dominant thermal mode after the display film is constructed, combined with the thermal and mechanical properties of the material.

[0118] Furthermore, the thermal gradient distribution data can be sampled in space and time by setting appropriate time intervals and spatial grids to obtain a three-dimensional temperature field matrix; the three-dimensional temperature field matrix can be processed by fast Fourier transform using professional mathematical calculation software (such as MATLAB) using the fast Fourier transform algorithm to obtain a frequency domain temperature matrix; the modal energy corresponding to the frequency domain temperature matrix can be calculated by summing the squares of the coefficients corresponding to each frequency component in the frequency domain temperature matrix, and based on the modal energy, the dominant thermal mode corresponding to the frequency domain temperature matrix can be analyzed by a sorting and screening method; based on the dominant thermal mode, the thermal distribution of the display film after construction can be reconstructed by combining thermoelasticity theory and finite element analysis software (such as ANSYS) to obtain a spatiotemporal stress distribution; based on the spatiotemporal stress distribution, the stress relaxation rate inside the display film after construction can be calculated by fitting the thermal stress data with an exponential function within a specific time interval, such as assuming that the change of thermal stress with time conforms to the function σ(t)=σ0e ―λt , where σ(t) is the thermal stress at time t, σ0 is the initial thermal stress, and λ is the stress relaxation coefficient. The thermal stress data within a specific time interval are processed by fitting methods such as the least squares method to determine the λ value. Then, based on the definition of stress relaxation rate (stress relaxation rate R = λ × 100%), the stress relaxation rate inside the display film after construction is calculated.

[0119] The present invention calculates the uniform attenuation coefficient of the interlayer structure of the display film based on the pressure load data, so as to understand the change of the uniformity of the interlayer structure of the display film over time or the construction process under the action of pressure, and provides a key quantitative basis for judging the long-term stability and quality reliability of the display film. It should be explained that the uniform attenuation coefficient indicates the degree to which the structural uniformity of the interlayer structure of the display film gradually decreases over time or under specific conditions under the action of factors such as pressure. The larger the coefficient, the faster the decay rate of the uniformity of the interlayer structure and the more unstable the structure.

[0120] In detail, the calculating of the uniform attenuation coefficient of the display film interlayer structure based on the pressure load data includes:

[0121] Performing spatial grid interpolation processing on the pressure load data to obtain a pressure distribution matrix;

[0122] Performing principal component analysis on the pressure distribution matrix to obtain a principal pressure component matrix;

[0123] Identifying interlayer structural components corresponding to the interlayer structure of the display film from the main pressure component matrix, and calculating the pressure gradient field corresponding to the interlayer structural components;

[0124] Based on the pressure gradient field, a uniform attenuation coefficient of the display film interlayer structure is calculated.

[0125] It should be explained that the pressure distribution matrix is the result obtained by performing spatial grid interpolation processing on the pressure load data, discretizing the pressure load data in space, filling the pressure values at each grid node through the interpolation algorithm, and presenting the pressure distribution at different spatial positions in the form of a matrix; the principal pressure component matrix is the result obtained by performing principal component analysis on the pressure distribution matrix, extracting the components that can reflect the main information of the original pressure data to the greatest extent from the pressure distribution matrix, and presenting these principal components in the form of a matrix; the interlayer structure component is the result obtained by identifying the interlayer structure of the display film from the principal pressure component matrix, and screening out the components related to the interlayer structure characteristics of the display film and capable of reflecting the response of the interlayer structure under pressure from the main pressure components; the pressure gradient field is the vector field reflecting the trend and direction of pressure change in the interlayer structure obtained by calculating the pressure change rate of the interlayer structure component in space corresponding to the interlayer structure component.

[0126] Furthermore, the pressure load data can be spatially gridded and interpolated by constructing a suitable spatial grid system and using algorithms such as bilinear interpolation and inverse distance weighted interpolation to obtain a pressure distribution matrix; the pressure distribution matrix can be principally analyzed by using the principal component analysis function built into statistical analysis software (such as SPSS, MATLAB) to obtain a principal pressure component matrix; the interlayer structure components corresponding to the display membrane interlayer structure can be identified from the principal pressure component matrix by combining the material properties, structural characteristics and pressure conduction theoretical knowledge of the display membrane interlayer structure; the pressure gradient field corresponding to the interlayer structure component can be calculated by using numerical calculation methods such as the central difference method and the finite volume method. For example, in a spatial discrete grid system, the central difference method can be used to divide the difference between the pressure values of adjacent grid nodes by the node spacing, or the finite volume method can be used based on the pressure flux balance relationship of the control body to accurately calculate the vector value of the pressure gradient field at each node.

[0127] Furthermore, as an optional embodiment of the present invention, calculating the uniform attenuation coefficient of the display film interlayer structure based on the pressure gradient field includes:

[0128] Based on the pressure gradient field, respectively calculating the gradient standard deviation and the gradient average corresponding to the interlayer structure of the display film;

[0129] Combining the gradient standard deviation and the gradient average, the uniform attenuation coefficient of the display film interlayer structure is calculated using the following formula:

[0130]

[0131] Where ω represents the uniform attenuation coefficient of the structure between the film layers, σ e Indicates the standard deviation of the gradient corresponding to the e-th structure in the interlayer structure of the membrane, μ e represents the average gradient value corresponding to the e-th structure in the display membrane interlayer structure, e represents the serial number corresponding to the display membrane interlayer structure, k represents the number of display membrane interlayer structures, and γ represents the stability constant.

[0132] It should be explained that the gradient standard deviation and the gradient average are the statistics corresponding to the interlayer structure of the display membrane for quantifying the pressure gradient change characteristics of the interlayer structure, wherein the gradient standard deviation reflects the degree of dispersion of the interlayer structure pressure gradient, and the gradient average represents the average level of the interlayer structure pressure gradient. The stability constant is a correction term to prevent the denominator from being too small, usually 0.1×μ e Furthermore, based on the pressure gradient field, the gradient standard deviation and gradient average corresponding to the interlayer structure of the display film can be calculated respectively by applying the standard deviation calculation formula and the average calculation formula in statistics.

[0133] The present invention evaluates the multi-dimensional structural stability of the display film by combining the stress relaxation rate and the uniform attenuation coefficient, which can comprehensively and accurately understand the stability change trend of the internal structure of the display film under the influence of multiple factors such as pressure and time, and provide a reliable basis for optimizing the design and preparation process of the display film. Furthermore, the multi-dimensional structural stability of the display film is evaluated by combining the stress relaxation rate and the uniform attenuation coefficient. For example, by comparing the numerical changes of the stress relaxation rate and the uniform attenuation coefficient at different time nodes, if the stress relaxation rate is low and the uniform attenuation coefficient is small, it indicates that the display film performs well in structural stress and interlayer uniformity, and has high multi-dimensional structural stability.

[0134] S4. Determine the composite gradient distribution strategy of the nano-composite material by combining the structural parameter information and the dynamic synergistic composite efficiency; formulate the preparation process parameters of the display film in the nano-composite construction according to the multi-dimensional structural stability performance and the composite gradient distribution strategy; and execute the composite construction preparation of the nano-composite material based on the preparation process parameters and the composite construction sequence to obtain a highly flexible display film finished product.

[0135] The present invention determines the composite gradient distribution strategy of the nano-composite material by combining the structural parameter information and the dynamic synergistic composite efficiency, fully considering the synergistic effect of the internal structure of the material and the various components, improving the scientificity and pertinence of the strategy, and formulating the preparation process parameters of the display film in the nano-composite construction according to the multi-dimensional structural stability and the composite gradient distribution strategy to ensure that the process parameters are accurately matched with the material performance requirements, and then executing the composite construction preparation process based on these preparation process parameters and the composite construction sequence to improve the stability of the preparation of the high-flexibility display film finished product. It should be explained that the composite gradient distribution strategy is a planning scheme determined by combining the structural parameter information and the dynamic synergistic composite efficiency to determine the proportion and change trend of the various components of the nano-composite material in different parts and different levels of the display film. The preparation process parameters are the specific operating conditions of the display film in the nano-composite construction from raw material processing to final molding.

[0136] Furthermore, the steps for determining the composite gradient distribution strategy of the nano-composite material are as follows: assuming that the structural parameters of the nano-composite material present a regular and orderly arrangement, the particle size distribution of each component is uniform and closely bound to each other, and at the same time the dynamic synergistic composite performance is excellent, and the components can respond synergistically quickly and efficiently under different external stimuli, then a progressive composite gradient distribution strategy is adopted. In the edge area of the display film, which is susceptible to external stress, the nanofiber component with enhanced toughness and fatigue resistance is distributed in a moderately increasing proportion, so that it can effectively disperse stress and protect the internal structure when subjected to external forces such as bending and stretching. In the central functional area of the display film, according to the display performance requirements, the proportion of nanoparticles with high transmittance and conductivity is gradually increased to ensure clear display and stable signal transmission. In the thickness direction, from the surface to the inside of the film, the nanosheet layer with barrier properties is distributed in a slowly decreasing manner, which not only ensures the protection of the surface from external environmental factors, but also does not affect the flexibility and other properties of the internal material.

[0137] Assuming that the structural parameters of the nanocomposite material show disordered arrangement of components, large differences in particle size and the presence of agglomeration, low dynamic synergistic composite efficiency, and serious mutual interference between the components, a centralized optimization composite gradient distribution strategy is adopted. On the surface of the display film, the material is first pretreated, and agglomerates are eliminated using methods such as ultrasonic dispersion and chemical modification. Then, nanomaterials that can improve surface smoothness and anti-pollution performance are concentratedly introduced to form a dense protective layer. In the sub-layer area near the surface, nano-components with repair functions are targeted and filled according to the structural defects of the material to improve the internal structure of the material. In the core area of the display film, by adjusting conditions such as temperature and pressure, large-sized particles are redispersed, and nano-components that enhance mechanical properties are concentratedly distributed at a higher concentration to rapidly improve the overall structural strength. At the same time, different components are partitioned, isolated, and arranged in a directional manner to reduce mutual interference and enhance synergistic effects, thereby obtaining the composite gradient distribution strategy of the nanocomposite material.

[0138] Furthermore, the present invention formulates the preparation process parameters of the display film in the nano-composite construction based on the multi-dimensional structural stability and the composite gradient distribution strategy. If the display film needs to have stable performance in a complex electromagnetic environment, the mixing order and stirring speed of the nanomaterials are adjusted in the preparation process so that the nano-components with electromagnetic shielding properties are evenly dispersed and directionally arranged, thereby enhancing the resistance to electromagnetic interference. At the same time, the pressure and time in the molding process are increased to promote close bonding between materials and optimize the internal structural stability. If the display film is required to maintain structural integrity under high and low temperature cycling environments, the nanomaterials are thermally pretreated in the raw material processing stage to adjust their thermal expansion coefficients to match the matrix. In the composite construction process, the heating and cooling rates are controlled to ensure that the material does not generate internal stress concentration when the temperature changes, thereby ensuring the structural stability and reliable performance of the display film.

[0139] Based on the preparation process parameters and the composite construction sequence, the composite construction preparation of the nano-composite material is performed to obtain a high-flexibility display film product, thereby improving the preparation quality stability of the high-flexibility display film. Furthermore, according to the composite construction sequence, the base material is first preheated to make it reach a state suitable for nanomaterial composite. Then, according to the preparation process parameters, through solution spin coating, magnetron sputtering, 3D printing and other technical means, according to the composite gradient distribution strategy, nanomaterials of different types and proportions are composited onto the base layer by layer. During the composite process, real-time monitoring equipment, such as an atomic force microscope, is used to monitor the structure and composition distribution of the material. Once a deviation is found, the process parameters are immediately adjusted. After multiple steps of fine construction and final post-processing steps such as annealing and cooling, a high-flexibility display film product is finally successfully prepared.

[0140] Compared with the problems described in the background technology, the present invention sets the composite construction sequence corresponding to the nano-composite material according to the application scenario of the display film and the structural parameter information, which can ensure that the composite process is highly adapted to actual needs, and lays an important foundation for the subsequent improvement of the performance and preparation efficiency of high-flexibility display films. Furthermore, the present invention calculates the interface coupling bonding strength of the nano-composite material during the composite process, and the interface coupling bonding strength can be used to understand the degree of bonding of the nano-composite material during the composite process, thereby providing an important basis for the subsequent analysis of the dynamic synergistic composite efficiency of the nano-composite material. The present invention calculates the stress relaxation inside the display film after the construction is completed based on the thermal gradient distribution data. rate, the attenuation characteristics of the internal stress of the display film over time can be understood, which provides an important basis for the subsequent evaluation of the multi-dimensional structural stability performance of the display film. Furthermore, the present invention determines the composite gradient distribution strategy of the nano-composite material by combining the structural parameter information and the dynamic synergistic composite efficiency, fully considering the synergistic effect of the internal structure of the material and the components, improving the scientificity and pertinence of the strategy, and formulating the preparation process parameters of the display film in the nano-composite construction according to the multi-dimensional structural stability and the composite gradient distribution strategy, ensuring that the process parameters are accurately matched with the material performance requirements, and then executing the composite construction preparation process based on these preparation process parameters and the composite construction sequence, thereby improving the stability of the preparation of the finished product of the highly flexible display film.
