Description

Technical Field

[0001] This invention relates to plasmon color development based on electrochemical deposition, specifically to a color development device, camouflage device, and driving color development method based on electrochemical deposition. Background Technology

[0002] Visible light camouflage technology is an important military "stealth" technology. In modern warfare, direct eye contact and optical photography are the most common strategic means for all parties to obtain intelligence and lock onto targets. Therefore, how to more effectively counter visual detection methods to ensure the safety and concealment of military targets has become a strategic problem that urgently needs to be solved in the military field. Traditional camouflage methods mainly use static camouflage materials, such as camouflage clothing of different colors and shapes. Although these materials can achieve camouflage effects to a certain extent, they have gradually lost their camouflage advantage because they cannot adapt to changes in the environment.

[0003] In recent years, plasmonic structural color has emerged as a new dynamic camouflage strategy, and its high contrast, high-definition color performance, and excellent physicochemical properties have broad application prospects in the field of camouflage technology. Olson J, Manjavacas A, Basu T, et al. High chromaticity aluminum plasmonic pixels for active liquid crystal displays[J].ACS Nano,2016,10(1):1108-1117. The literature mentions the use of transmissive LC dielectric conductors to achieve dynamic structural color, and the use of LC electrical switches to open and close a metasurface composed of plasmonic aluminum nanorod arrays. When polarized light is incident along the pixel plane parallel to the nanorod axis, the scattered light produces a bright color. This method assembles a 6 mm thick nematic LC layer on the pixel and observes the scattered light in front of a linear polarizer, effectively controlling the opening and closing state of the pixel. When there is no power on the LC layer, the 90° polarization rotation matches the direction of the output polarizer, making the finished color visible. When the voltage is 20V, the unrotated scattered light from the pixel is blocked by the output polarizer, causing the color display to turn off. Xu T, Walter EC, Agrawal A, Bohn C, Velmurugan J, Zhu W, Lezec HJ, Talin AA. High-contrast fast electrochromic switching enabled by plasmonics. Nat Commun. 2016 Jan 27; 7:10479. This paper mentions the use of a plasmonic nanoslit array functionalized with polyaniline and PolyProDOT-Me2 to achieve high-contrast, fast-color-changing, full-color-changing switching. By adjusting the period of the nanoslit array, the entire visible spectrum can be covered. During operation, the material with mixed plasmonic dynamic structural colors operates in transport mode, and the polymer cycles between its transparent (colored) and absorbing (uncolored) states.

[0004] Wang G, Chen X, Liu S, et al. Mechanical chameleon through dynamic real-time plasmonic tuning[J].ACS Nano, 2016, 10(2): 1788-1794. The literature describes a method based on a combination of bimetallic nanodot arrays and electrochemical bias to modulate plasmonic structural colors. The team fabricated a biomimetic mechanical chameleon and an active matrix display that dynamically displays colors using this method. By processing sensor data with a microcontroller and outputting voltage to control the display's color display, they ultimately achieved visual camouflage in changing environments.

[0005] While liquid crystals and electrochromic color modulation are powerful and relatively fast, using liquid crystals for dynamic plasmon color reconstruction requires polarization devices, and using electrochromic materials necessitates multiple color configuration trials. This means that liquid crystal and electrochromic material technologies incur redundant manufacturing costs and also result in lower brightness performance. CN116609977A discloses a plasmon device and its fabrication method, in which metal ions in an electrolyte are deposited and grown into plasmon structures on a core-shell structure. By adjusting the current density and controlling the time, the size of the metal nanoparticles deposited or extracted can be controlled. This method of using reversible electrochemical deposition for plasmon color reconstruction can solve the redundancy problems of liquid crystals and electrochromics. However, traditional electrochemical deposition devices often require complex micro / nano structure design and fabrication, greatly increasing manufacturing costs. Summary of the Invention

[0006] Purpose of the invention: The purpose of this invention is to provide an electrochemical deposition colorimetric device based on voltage regulation without requiring a complex micro / nano structure on the substrate. Another purpose of this invention is to provide a camouflage device based on the electrochemical deposition colorimetric device. A further purpose of this invention is to provide a driving colorimetric method for the camouflage device based on the electrochemical deposition colorimetric device.

[0007] Technical solution: An electrochemical deposition colorimetric device of the present invention includes an insulating substrate, a first electrode and a second electrode spaced apart on the insulating substrate, and an electrolyte filling the space between the first electrode and the second electrode; the second electrode includes a stacked metal adhesion layer and a metal current collector; the first electrode serves as the positive electrode, the metal current collector serves as the negative electrode, and together with the electrolyte, they form an electrochemical cell.

[0008] Furthermore, the insulating substrate is a rigid or flexible insulating material.

[0009] Furthermore, the first electrode is LiCoO2, LiFePO4, or Li x MnO2, where 0.2≤x≤1.5, LiNiO2, LiVO2, ternary lithium nickel cobalt manganese oxide, ternary lithium nickel cobalt aluminum oxide, NaNiO2, NaCoO2, Na x MnO2, where 0.2≤x≤1.5, NaFePO4, NASICON-type materials, and Prussian blue compounds.

[0010] Furthermore, the metal adhesion layer is made of chromium, aluminum, titanium, vanadium, or TiW, with a thickness of 5–10 nm.

[0011] Furthermore, the metal current collector layer is made of tungsten, copper, or zinc, with a thickness of 50 nm to 1 μm and a surface roughness of less than 10 nm. The negative electrode material has high conductivity and high reflectivity, but poor affinity with the positive electrode metal, making it difficult to form an alloy. An excessively thin current collector results in insufficient conductivity, affecting the uniformity of the electrochemical reaction; an excessively thick current collector increases surface roughness, leading to uneven growth of metal particles. Excessively high surface roughness causes metal particles to preferentially grow in localized areas, forming dendrites or agglomerates, affecting optical display performance and electrochemical properties.

[0012] Furthermore, the metal adhesion layer and the metal current collector are bonded together through physical vapor deposition.

[0013] The camouflage device based on an electrochemical deposition colorimetric device of the present invention includes an intelligent sensing and control system for switching the output control voltage and an electrochemical deposition colorimetric device based on control voltage regulation; the intelligent sensing and control system includes an optical sensor module for color recognition, a microcontroller module for processing color digital signals and accurately outputting control voltage values, and a digital-to-analog converter voltage output module for output voltage.

[0014] Furthermore, the optical sensor module includes a color sensor module and serial port tool software for analyzing the color data output by the application.

[0015] Furthermore, the optical sensor module integrates an infrared blocking filter to reduce the incidence of infrared spectral components.

[0016] The driving color development method of the camouflage device based on the electrochemical deposition color development device of the present invention includes the following steps:

[0017] Step 1: The optical sensor module reads the colors of the surrounding environment and converts them into numerical values.

[0018] Step 2: The microcontroller module processes the values ​​output in Step 1 and converts them into voltage values.

[0019] Step 3: The digital-to-analog converter voltage output module outputs a constant voltage according to the voltage value output in Step 2.

[0020] Step 4: The electrochemical deposition colorimetric device controls the spatiotemporal distribution of the nucleation and growth of deposited metal particles based on the different constant voltages output in Step 3, thereby switching the color display in real time.

[0021] Working Principle: The electrochemical deposition colorimetric device constitutes an electrochemical cell. Utilizing the plasmon optical properties of metals in the reaction, the negative electrode metal serves as both the negative electrode structure and the display panel of the electrochemical deposition colorimetric device. During charging, the metal nucleates and grows on the negative electrode structure. Metal particles with different spatial distributions and sizes exhibit different colors. During discharging, the metal peels off from the negative electrode substrate, and the plasmon structure color disappears. The negative electrode substrate does not require complex micro / nano structures for controlling metal particle growth. Instead, the spatial distribution and size evolution of metal particles on the negative electrode substrate are controlled in time and space through voltage-time sequence control during charging. By understanding the relationship between the applied voltage and the energy required for metal particle nucleation and growth, the spatiotemporal nucleation and growth can be controlled, thereby controlling the spatiotemporal distribution of metal particles and thus regulating color evolution.

[0022] The camouflage device based on electrochemically deposited color-developing devices identifies color changes in the surrounding environment through external optical sensors. The read color information is then expressed using a systematic numerical representation. This data is processed by a microcontroller, which in turn drives a digital-to-analog converter (DAC) to output a constant analog voltage. The voltage value changes in response to continuous light signal readings from the optical sensors. The electrochemically deposited color-developing device in the system adjusts its optical characteristics according to the voltage level to match its color with the surrounding environment, achieving dynamic camouflage and invisibility. This demonstrates intelligent dynamic environmental color detection, dynamic voltage signal output, and dynamic color display. Furthermore, the electrochemically deposited color-developing device can also be used as a battery module, leveraging its charge-discharge characteristics to integrate display and energy storage.

[0023] Beneficial effects: Compared with the prior art, the present invention has the following significant features: the electrochemical deposition colorimetric device has a simple fabrication process and can reduce costs; it does not require complex micro-nano structures, and achieves color evolution control of color camouflage based on the spatiotemporal distribution evolution process of voltage-regulated metal particles, thereby realizing the integration of colorimetric function and energy storage function.

[0030] Unless otherwise specified, all materials and reagents used in the following embodiments are commercially available. Experimental methods not specifically described in the embodiments are generally performed under standard conditions or as recommended by the manufacturer.

[0031] Example 1

[0032] like Figure 1 and Figure 2 As shown, the insulating substrate 1 of the electrochemical deposition colorimetric device is made of SiO2 rigid insulating material, and the first electrode 2 is made of lithium cobalt oxide (LiCoO2). Specifically, the first electrode 2 material can be replaced with LiFePO4, Li x MnO2, where 0.2≤x≤1.5, LiNiO2, LiVO2, ternary lithium nickel cobalt manganese oxide, ternary lithium nickel cobalt aluminum oxide, NaNiO2, NaCoO2, Na x MnO2, wherein 0.2≤x≤1.5, NaFePO4, NASICON-type materials, and Prussian blue compounds. The metal adhesion layer 5 of the second electrode 3 is a chromium layer with a thickness of 5 nm, on which a tungsten current collector 6 with a thickness of 100 nm and a surface roughness of 2 nm is stacked. The electrolyte 4 is lithium trifluoromethanesulfonylimide (LiTFSI), with 1% LiNO3 lithium salt added to a solvent of 1,3-dioxolane (DOL): ethylene glycol dimethyl ether (DME) = 1:1. Differentiated voltage input excitation was applied to the electrochemical deposition colorimetric device of Example 1 to control the precipitation and dissolution of lithium metal particles deposited on the surface of the tungsten current collector 6. Different growth conditions of lithium metal particles on the surface of the particle layer of the metal current collector 6 exhibited different spectral characteristics, thereby allowing for visible light modulation. There is no need to set up micro / nano structures on the substrate for fixing metal nucleation sites; by controlling the voltage relative to the equilibrium potential, the nucleation growth can be controlled, and the spatial and temporal distribution of metal nucleation growth can be regulated. The electrode reactions of an electrochemical cell during charging and discharging are as follows:

[0033] During charging, the electrode reactions are as follows:

[0034] First electrode: LiCoO2 → Li 1-xCoO2+xLi + +xe -

[0035] Second electrode: xLi + +xe - →xLi

[0036] During the discharge process, the electrode reactions are as follows:

[0037] First electrode: Li 1-x CoO2+xLi + +xe - →LiCoO2

[0038] Second electrode: xLi → xLi + +xe -

[0039] When a voltage of 4.5V is applied to the electrochemical deposition colorimetric device of Example 1, the device will be in the charging process. The tungsten metal current collector 6, acting as the negative electrode, will gain electrons in the redox reaction, while the lithium cobalt oxide, acting as the positive electrode, will lose electrons. During the charging process, lithium ions in the electrolyte 4 will gain electrons and be reduced and deposited on the surface of the tungsten metal current collector 6 negative electrode. Figure 2 The lithium particles shown exhibit a nucleation process in the early stages of electrochemical deposition. During growth, the lithium particles adhere to the surface of the tungsten metal current collector, and their gradual increase in size alters the ablation spectrum of the device's negative electrode region. This results in selective light response and different color displays. When a voltage of approximately 2.5V is applied, the device undergoes a discharge process. The metallic lithium, acting as the negative electrode, loses electrons and dissolves into lithium ions, while lithium cobalt oxide, acting as the positive electrode, gains electrons and intercalates into lithium ions. During discharge, the previously deposited lithium atoms gradually lose electrons to form lithium ions and reintegrate into the electrolyte. This process accelerates as the applied voltage decreases, ultimately restoring the device to its original state and allowing for reuse.

[0040] like Figure 4 As shown, the electrochemical deposition color development device 8 under constant voltage excitation exhibits its color development state at different time points and the reflectance of each color development state. During the charging process, a constant voltage of 5V is applied to the electrochemical deposition color development device 8 for 2 seconds. At this time, the voltage of 5V is higher than the voltage required for growth. After a brief 2-second nucleation process, the charging voltage can be slightly reduced to 4.5V to allow for the growth of lithium particles until the charging is complete. During this period, a clear color state transition can be observed under a microscope. The process lasts approximately 28 seconds, and the overall color state of the device under the microscope shows a smooth trend from violet to red light. Figure 5This describes the color change of the device under constant voltage excitation. Each color block represents the actual color display state of the device under different time conditions under constant voltage excitation. The device rapidly changes color after being powered on, reaching purple in 1 second, quickly changing to blue in 3 seconds, and turning green after 8 seconds of charging. Thereafter, the device smoothly switches between cyan, brown, and yellow every 5 seconds, then turns red after 4 seconds, and finally displays pink for 2 seconds before gradually appearing as pure black under a microscope. The electrochemical deposition color display device 8 has a dynamically adjustable color range of 400-850nm in the visible light region, with a response time in the second range; the response time varies for different colors.

[0041] The method for fabricating electrochemically deposited colorimetric devices includes the following steps:

[0042] Step 1: Cleaning: Take a clean beaker, rinse the inner wall with analytical grade ethanol and deionized water, rinse off the liquid with a nitrogen gun and dry for later use. Place a SiO2 sheet in the beaker, remove surface impurities with acetone, and then ultrasonically clean for later use.

[0043] Step 2, Coating: Magnetron sputtering is used for coating. SiO2 sheets are fixed to the surface of a copper plate with carbon adhesive. After covering half of the sheet with high-temperature resistant insulating tape, it is placed on a coating rotating stage for uniform coating. The parameters of the coating instrument, molecular pump, vacuum gauge and other related instruments are set. After the vacuum in the coating instrument cavity reaches the standard, cooling water is introduced. Ionized stable argon molecules are used to bombard the chromium metal target. Empty coating for 5 minutes to ensure no impurities interfere. Then, chromium atoms are used to deposit the sheet for 8 minutes to form a metal adhesion layer. Then, ionized argon molecules are used to bombard the tungsten metal target to sputter tungsten atoms. The tungsten coating process takes 1 hour.

[0044] Step 3: Assembly: Lithium cobalt oxide is bonded to SiO2 sheets using UV adhesive, and a tungsten electrode is brought out using copper glue. The UV adhesive is then used to fix the electrode to the copper glue surface to prevent side reactions during the reaction process. A device with an internal cavity is then formed using a two-layer SiO2 sheet structure. After injecting electrolyte into the device, UV adhesive is applied and the device is thoroughly irradiated with a UV lamp for approximately 25 seconds to cure the UV adhesive. This completes the assembly of the device, resulting in an electrochemically deposited colorimetric device.

[0045] like Figure 3As shown, the electrochemically deposited colorimetric device 8 prepared in Example 1 is used in a camouflage device. The camouflage device includes an intelligent sensing and control system 7 capable of switching output control voltage for environmental perception and circuit feedback, and an electrochemically deposited colorimetric device 8 based on control voltage regulation. The intelligent sensing and control system 7 includes an optical sensor module 9 for color recognition, a microcontroller module 10 for processing color digital signals and accurately outputting control voltage values, and a digital-to-analog converter voltage output module 11 for output voltage. The optical sensor module 9 uses a TCS34725 as the optical sensor color recognition module 12. The TCS34725 color sensor module 12 provides numerical outputs of RGB and clear light sensing values ​​for red, green, and blue colors, and outputs reference values ​​for HSL color space values ​​that correspond one-to-one with the RGB system. The optical sensor module 9 integrates an infrared blocking filter to minimize the incidence of infrared spectral components, achieving accurate color measurement. For the data output application of the TCS34725 color sensor module 12, analog communication is performed using the SSCOMV5.13.1 serial port tool software 12. The RGB values, HSL values, and clear light sensing value C of the background color are observed using the SSCOMV5.13.1 serial port tool software 12 to achieve real-time observation and analysis of the background color. The digital-to-analog converter voltage output module 11 uses the DAC8563. The DAC8563 is a low-power, dual-channel, voltage output, 16-bit data converter DAC. The DAC8563_V2.0 used can output a voltage range of 10V. The microcontroller module 10 uses a development board based on the STM32F103RCT6 chip. The microcontroller is the core of the intelligent sensing control system, processing the digital color information signals from the TCS34725 optical sensor module 9 and controlling the DAC8563 to accurately output the corresponding analog voltage values ​​to control the optical characterization state of the electrochemically deposited color display device 8 in the color display system.

[0046] By changing the voltage and time parameters of electrochemical deposition, fine-tuning of the color can be achieved. During the voltage-excitation testing of device 8, the corresponding voltage-time parameters and the spectrum are determined, such as... Figure 4 As shown, after the color sensor TCS34725 collects the color information of the environment, it selects the H information in HSL as the judgment criterion for the microcontroller module 10 to perform the operation, and initially and simply divides the colors into categories such as... Figure 4The system uses seven color sensors, assigning H information to colors: purple (H(270°, 330°)), blue (210°, 270°)), green (90°, 150°)), cyan (150°, 210°)), brown (60°, 90°)), yellow (30°, 60°)), and red (0°, 30°) + (330°, 360°). When the color sensor reads the H information, the microcontroller module 10 outputs a voltage excitation corresponding to the time to control the size of the metal particles and ultimately determine the color display. After the expected color is determined, the microcontroller module 10 controls the output balance voltage to stabilize the device color. The preferred balance voltage is 3.9V (±0.1V). To verify the environmental camouflage performance of the dynamic camouflage device based on the electrochemical deposition device, the optical performance of the camouflage device was tested under purple, blue, and green ambient colors. Color information was read from different colored cards using sensors, and the microcontroller module 10 and the digital-to-analog converter voltage output module 11 output analog voltage values ​​to control the color development of the electrochemical deposition color development device 8. Figure 6 As shown. Figure 6 The upper part is where the optical sensor module 9 reads color information. Figure 6 The lower half shows the color change of the electrochemically deposited colorimetric device 8 from the corresponding macroscopic perspective.
