Description

Technical Field

[0001] This invention relates to the field of superconducting materials technology, specifically to a method for preparing a carbon-based room-temperature superconducting material based on frequency resonance matching. Background Technology

[0002] Superconducting materials possess zero resistance and perfect diamagnetism, laying the foundation for applications in power transmission, magnetic levitation, and quantum electronic devices. However, existing superconducting materials are typically subject to strict limitations imposed by their service environment. Traditional copper oxide or iron-based superconducting materials require extremely low temperatures to maintain their internal electron pairing states. While some hydrogen-rich compounds have improved critical transition temperatures, the stability of their physical structures still relies on ultra-high pressure environments. This dependence on extremely low or high temperatures increases the complexity and operating costs of material application systems, hindering the large-scale engineering applications of superconducting materials.

[0003] To overcome the constraints of extreme environments, the development of novel superconductors operating at room temperature and pressure has become a key focus, with some carbon-based composite materials or chemical doping being introduced into this field. However, in the macroscopic environment of room temperature and pressure, materials face severe thermal fluctuation disturbances. The thermal energy provided by the room temperature environment continuously excites the lattice and local electrons, making it difficult for the characteristic frequency of electron transport within the material to keep synchronized with the vibrational frequency of the local polarization center, resulting in frequency mismatch and energy dissipation. At the same time, thermal excitation phenomena can disrupt the spatial configuration of molecular dipoles, causing random flipping and dielectric relaxation of the polarization array, which in turn triggers decoherence effects in the system. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a method for preparing carbon-based room-temperature superconducting materials based on frequency resonance matching, which solves the problem of strong thermal fluctuations and decoherence effects generated in room-temperature thermal reservoirs in existing superconducting theories.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a carbon-based room-temperature superconducting material based on frequency resonance matching, wherein the superconducting material is made from raw materials comprising the following mass parts: three-dimensional porous graphynylene-C 18 100 parts of heterogeneous covalent network framework; 90-110 parts of isotopically confined fullerene mixture, wherein the isotopically confined fullerene mixture includes hydrogen fluoride confined fullerene, deuterium fluoride confined fullerene and tritium fluoride confined fullerene; 7-35 parts of alkali metal atoms.

[0006] By adopting the above technical solution, since a tensile heterogeneous covalent network framework is used as the electron transport channel and an isotopically confined fullerene mixture is used as the polarization center, the system establishes physical boundary conditions that satisfy the generalized operator dynamics principle under macroscopic room temperature conditions. The transport frequency operator of itinerant electrons in the framework material and the vibration frequency operator of the local polarization center have a commutator result of zero, and the thermal fluctuation term that destroys the system coherence is also zero. The three-dimensional porous graphdiyne network eliminates the low-frequency phonon soft mode, and the dense aromatic electron cloud of fullerene cuts off the long-range disordered scattering channel, isolating the local zero-fluctuation environment. This achieves the effect that the characteristic frequency of electrons flowing through the framework is equal to the vibration frequency of the dipoles in the cage, thereby generating phase-difference-free resonant coupling and eliminating energy dissipation during electron transport.

[0007] Preferably, the total mass ratio of the heterogeneous covalent network framework to the isotopically confined fullerene mixture is 1 to 0.9 to 1.1; the molar ratio of the alkali metal atoms to the total fullerene carbon cage is 1.5 to 2.5 to 1.

[0008] By adopting the above technical solution, the physical spatial matching degree between the framework lattice and the polarization center is ensured by using a specific mass and molar ratio. Therefore, obtaining a localized distribution of alkali metal atoms can provide the effect of appropriate lattice extrusion stress.

[0009] Preferably, the isotope-confined fullerene mixture exhibits a gradient micro-distribution across the three-dimensional depth of the material. From the microfluidic bottom layer to the surface layer, the content of hydrogen fluoride-confined fullerenes shows a linear decreasing trend, while the content of tritium fluoride-confined fullerenes shows a linear increasing trend.

[0010] By adopting the above technical solution, a continuous polarized dipole vibration characteristic frequency band is constructed in the three-dimensional space of the material by utilizing the isotopic differences in the mass of hydrogen, deuterium, and tritium. Therefore, the effect of broadening the frequency resonance capture window and ensuring that there is a physical region at the crystal domain level that coincides with the reference electron transport frequency is obtained.

[0011] Preferably, the three-dimensional porous graphynylene and C 18 The heterogeneous covalent network framework was constructed using vacuum electrospray deposition technology, with a monolayer coverage of 10%-30% in cyclic C46 ... 18 Three-dimensional porous graphdiyne molecular clusters are uniformly sprayed onto the molecular array and the temperature is programmed to be raised to 273K to 298K, so that a covalent cross-linked structure is formed by spontaneous cycloaddition reaction at the contact interface.

[0012] By adopting the above technical solution, since the highly active molecular array and the porous framework are cross-linked in situ in a solvent-free high vacuum environment, the introduction of impurities and defects is avoided. Therefore, the effect of ensuring the structural integrity of the carbon-based network and maintaining the high-frequency phonon rigid environment required for electron transmission is achieved.

[0013] Preferably, the polarized molecular dipoles inside the material exhibit a uniform cisional configuration, which is rigidly solidified by microcovalent bonds formed through deep ultraviolet light crosslinking. Its maximum dielectric loss tangent at room temperature is less than 1.5 x 10^6. -3 .

[0014] By adopting the above technical solution, the geometric asymmetry of the microscopic quantum state is fixed by the chemical covalent bond network, which effectively resists the random flipping of molecular dipoles caused by room temperature thermal excitation. Therefore, the effect of eliminating dielectric relaxation dissipation and achieving long-term self-sustaining of the dipole array against thermal disturbance is achieved.

[0015] A method for preparing carbon-based room-temperature superconducting materials based on frequency resonance matching includes the following steps: S1, mix the graphyne with C 18 The heterogeneous covalent network framework was dispersed in anhydrous chlorobenzene to form an insulating suspension. A multi-channel microfluidic pump was used to sequentially and programmatically drip a solution of hydrogen fluoride confined fullerene, deuterium fluoride confined fullerene, and tritium fluoride confined fullerene dissolved in anhydrous chlorobenzene into the insulating suspension to construct a micro-gradient distribution of isotopic composition. S2. In the liquid phase state after the microfluidic titration is completed and the solvent has not evaporated, a rotating vector spatial electric field is applied externally. Then, while keeping the electric field on, the reaction in the microchannel is continuously photocrosslinked by irradiating with a deep ultraviolet light source to form micro-covalent bonds and lock the phase. S3. After the solvent evaporates at a constant temperature, the composite powder is moved into one end of the vacuum chamber, and the alkali metal azide is placed at the other end. The alkali metal azide is heated and decomposed under dynamic continuous vacuum to remove the generated nitrogen gas. After the system returns to high vacuum, the chamber is sealed and heated in a dual-temperature zone to allow the alkali metal vapor generated by denitrification to be localized and inserted into the interstices of the composite powder. After cooling, the final composite material is obtained.

[0016] By adopting the above technical solutions, the boundary points that satisfy the coherence conditions were locked through physicochemical means, achieving the following effects: First, the microfluidic gradient titration self-assembly step of the insulating precursor state broadens the continuous vibrational frequency band within the material body by controlling the spatial position of isotope molecules, providing a fault-tolerant basis for frequency alignment; Second, the liquid-phase dynamic polarization and in-situ ultraviolet phase-locking steps utilize the early dielectric insulating state of the material, avoiding the electrostatic shielding effect generated by the conductive network after solid-state forming, allowing the external rotating electric field to penetrate and unify the orientation of polarized molecules; The synchronously introduced photocrosslinking reaction transforms this orientational physical state into chemical bond connections, overcoming the problem of thermally induced depolarization under room temperature conditions; Finally, the desolvation and localized gas-phase intercalation steps allow gaseous alkali metal atoms to enter specific lattice interstitial positions; Due to the occupancy effect of metal atoms, the lattice expands and applies isotropic compressive stress to the internal fullerene carbon cage; This chemical stress causes the physical volume within the cage to shrink, thereby compressing the frequency band constructed by the microfluidic steps towards the target resonance frequency point, achieving consistency between the transmission frequency and the vibrational frequency.

[0017] Preferably, in S1, the mass concentration of the skeleton insulating suspension is 2.0 to 3.0 mg / mL, and the concentration of each isotope-confined fullerene solution is 1.5 mg / mL. During microfluidic titration, the ambient temperature is controlled at 20 to 25 degrees Celsius, and the total titration time is divided into three continuous periods: in the first period, pure hydrogen fluoride-confined fullerene solution is titrated at a constant rate; in the second period, the titration rate of the hydrogen fluoride-confined fullerene solution linearly decreases to zero, while the titration rate of the deuterium fluoride-confined fullerene solution linearly increases from zero to a peak value; in the third period, the titration rate of the deuterium fluoride-confined fullerene solution linearly decreases to zero, while the titration rate of the tritium fluoride-confined fullerene solution linearly increases from zero to a peak value.

[0018] By adopting the above technical solution, the use of a controlled fluid program ensures a continuous transition of the three isotopic mass molecules in the material thickness direction, thus avoiding the internal lattice stress fracture and frequency span interruption caused by abrupt concentration changes.

[0019] Preferably, in S2, the electric field strength of the rotating vector spatial electric field is 2.0 multiplied by 10. 4 Up to 5.0 multiplied by 10 4 The specific implementation method of the deep ultraviolet in-situ phase lock is as follows: the polarized suspension is continuously pumped into the quartz thin-layer liquid flow pool in a laminar flow form, and the thin-layer liquid film flowing through it is irradiated on both sides using a deep ultraviolet light source with a wavelength of 254 nanometers and an irradiation intensity of 20 to 40 milliwatts per square centimeter, and the photocrosslinking is carried out continuously for 40 to 60 minutes.

[0020] By adopting the above technical solution, the absorption and internal filtration effect of carbon-based suspension on ultraviolet light is solved by using a thin-layer liquid flow pool and a double-sided transmission structure. Therefore, the effect of uniformly receiving photon energy by dipole molecules in each layer of the interior is achieved, ensuring that the cross-linking of microscopic covalent bonds is completed within the reaction.

[0021] Preferably, in step S3, the parameters for solvent removal are: constant-temperature evaporation at a vacuum of 10⁻⁴ Torr and a temperature of 40 to 50 degrees Celsius for 24 hours to induce an insulating-to-metal phase transition; the vacuum chamber is a quartz ampoule, and the source end is slowly heated to 300 degrees Celsius under dynamic exhaust and denitrification conditions, with the system recovering for 10 seconds. -5 Torr post-sealing; localized vapor phase intercalation stage, the composite powder end is maintained at 200 to 220 degrees Celsius, the alkali metal source end is heated to 300 to 350 degrees Celsius, and the isothermal reaction is carried out for 48 to 72 hours.

[0022] By adopting the above technical solution, the physical vapor phase dual-temperature zone transport process combined with the pre-dynamic denitrification step eliminates the penetration of non-metallic impurity gases into the crystal lattice. Therefore, it achieves the effect of precisely controlling the partial pressure and diffusion kinetics of metal vapors and ensuring the uniformity and localization accuracy of alkali metal atom intercalation.

[0023] Preferably, in S3, the alkali metal azide is rubidium azide or potassium azide; and, before the microfluidic gradient titration self-assembly step of the insulating precursor state, the three types of confined fullerenes are pre-prepared as follows: fullerenes with a purity of not less than 99.9% are mixed with triazine derivatives under reflux conditions to prepare ring-opening fullerene derivatives, and then the ring-opening fullerene derivatives are placed in a high-pressure reactor and maintained at 2000 standard atmospheres and heated to 200 degrees Celsius for 36 hours, while anhydrous hydrogen fluoride gas, deuterium fluoride gas, or tritium fluoride gas are introduced and pressurized respectively, and finally, at 10 -3 Torr pyrolyzes the stitched carbon cage by heating it to 340 degrees Celsius under vacuum.

[0024] By adopting the above technical solution, a closed structure is formed by combining high-pressure physical filling with high-temperature pyrolysis stitching mechanism. Therefore, the retention rate of polar gas molecules inside the fullerene is guaranteed, laying the material basis for providing polarization centers in the future.

[0025] Preferably, the carbon-based room-temperature superconducting material prepared by the metal intercalation vapor-phase extrusion process after the three-dimensional composition broadening, desolvation, and localization vapor-phase intercalation steps in S1 has a zero-magnetic-field cooling volume magnetic susceptibility of no more than -0.88 under normal pressure at 298K, and the absolute difference between its framework lattice electron transport frequency and the local polaron vibration center frequency is less than 0.1 terahertz.

[0026] By adopting the above technical solution, the material exhibits a room-temperature Meissner effect and a small frequency difference at the macroscopic level, which confirms that the preparation process enables the material to construct a quantum coherent state that repels the applied magnetic flux. Therefore, the effect of achieving room-temperature superconductivity at room pressure is obtained.

[0027] This invention provides a method for preparing a carbon-based room-temperature superconducting material based on frequency resonance matching. It has the following beneficial effects: 1. This invention employs isotope microfluidic gradient distribution technology combined with localized alkali metal vapor phase intercalation process to construct a continuous polarized dipole vibration frequency band in the three-dimensional space of the material, and applies isotropic chemical compressive stress to the internal fullerene carbon cage through the occupancy effect of metal atoms; it achieves resonance matching between the electron transport frequency of the framework lattice and the vibration center frequency of the local polaron, eliminates energy dissipation in the electron transport process, and thus establishes a stable macroscopic quantum coherent state and Meissner diamagnetic properties under normal temperature and pressure environment.

[0028] 2. This invention employs liquid-phase dynamic polarization and thin-layer deep ultraviolet in-situ crosslinking technology to unify the spatial orientation of polarized molecules when the material is in a dielectric insulating state, and simultaneously form a micro-covalent bond network, transforming this physical orientation state into a lasting chemical connection; effectively resisting the random flipping and depolarization effect of molecular dipoles caused by room temperature thermal environment, overcoming the problem of thermal fluctuation at room temperature, and enabling the polarization dipole array inside the material to achieve long-term self-sustaining and maintain extremely low dielectric loss.

[0029] 3. This invention utilizes vacuum electrospray deposition technology to construct three-dimensional porous graphylene and C in situ under a solvent-free high vacuum environment. 18 The heterogeneous covalent network framework provides a rigid electron transport channel with tension, eliminating the low-frequency phonon soft mode of the material. At the same time, the dense aromatic electron cloud of fullerene cuts off the long-range disordered scattering path, providing a stable material and structural basis for the system to isolate a local zero-fluctuation environment.

[0043] Example 4: This example provides a method for preparing a carbon-based room-temperature superconducting material based on frequency resonance matching, including the following steps: The first step is exactly the same as the first step in Example 1 in terms of process conditions, raw material sources, and proportioning parameters. The second step involves the same process conditions and parameters as the second step in Example 1. The third step is to turn off the ultraviolet light and electric field, and transfer the composite powder to a vacuum drying oven at 10°C. -4 The solvent was evaporated at a constant temperature of 45°C for 24 hours under a vacuum of Torr. The dried composite powder was placed at one end of a quartz ampoule, and potassium azide powder was placed at the other end as a potassium source. The ampoule was then connected to a vacuum system and evacuated to 10°C. -5 Torr, under dynamic continuous vacuum, slowly heats the potassium source end to 300°C to completely decompose potassium azide into metallic potassium and removes the generated nitrogen gas; after the system returns to high vacuum, seals the ampoules; place them in a dual-temperature zone tube furnace, maintaining the composite powder end at 210°C and heating the metallic potassium end to 300°C; control the potassium atoms and total C... 60 The molar ratio was 2.0:1, the reaction was carried out at a constant temperature for 60 hours, and the furnace was naturally cooled to room temperature to obtain a terminal composite material containing potassium atoms.

[0044] Comparative Example 1 differs from Example 1 in that the graphylene-C obtained in Preparation Example 1 was not used in the first step. 18 Instead of a heterogeneous covalent network framework, pure C that is not cross-linked with the graphynylene template is used directly. 18 The network participates in the assembly; everything else is the same.

[0045] Comparative Example 2 differs from Example 1 in that, in the first step, instead of using three isotope-confined fullerenes for microfluidic gradient titration, only a single HF@C at a mass concentration of 1.5 mg / mL was used. 60 The solution was continuously dripped at a constant rate of 0.5 mL / min for 120 minutes, and no micro-gradient distribution of isotopic components was constructed, but all other aspects were the same.

[0046] Comparative Example 3 differs from Example 1 in that the rotating vector space electric field treatment in the insulating liquid phase state in the second step is omitted. Instead, after desolvation and the insulating-metal phase transformation into macroscopic conductive solid powder in the third step, a rotating vector space electric field with the same parameters is applied externally for polarization. All other aspects are the same.

[0047] Comparative Example 4 differs from Example 1 in that only a rotating vector spatial electric field is applied in the second step to polarize the liquid phase, but the deep ultraviolet light source is not turned on for in-situ photocrosslinking and phase locking throughout the process, that is, no micro-covalent bonds are formed in the solidified spatial configuration and the internal dipole direction. All other aspects are the same.

[0048] Comparative Example 5 differs from Example 1 in that the localized gas-phase intercalation process in the third step is completely omitted. Instead, the suspension after liquid-phase treatment is directly desolvated and dried as the final composite material. No rubidium atoms are introduced for pyrolysis intercalation to generate intrinsic chemical stress. All other aspects are the same.

[0049] Test Example 1: This test example provides a frequency resonance testing method based on broadband terahertz time-domain spectroscopy and inelastic neutron scattering. The specific test steps are as follows: The terminal composite material powders obtained in each embodiment and comparative example were ground thoroughly in an agate mortar and pressed into test sheets with a diameter of 13 mm and a thickness of 1 mm using a tablet press at a pressure of 15 MPa. The tablet pressing process was carried out in a glove box filled with high-purity nitrogen to avoid interference from air absorption on the spectral baseline. The pressed sample sheet was placed in the sample chamber of the inelastic neutron scatterer. The incident neutron energy was set to 150 meV and the energy resolution was set to ΔE / E≤2%. Neutron scattering spectrum in momentum transfer space was collected at room temperature of 298K. The characteristic phonon dispersion relation of lattice electron transport was extracted by scattering cross section data. After integral fitting, the transport frequency operator center value of itinerant electrons in the framework lattice was obtained. Thin slices of the same batch were transferred to a broadband terahertz time-domain spectrometer, with the system operating temperature maintained at 298 K and relative humidity controlled below 5%. Femtosecond laser pump-probe technology was used for continuous scanning in the frequency range of 10 THz to 120 THz. The transmitted terahertz time-domain waveform was recorded, and the frequency-domain absorption spectrum was obtained through fast Fourier transform. CL was extracted by multi-peak Gaussian peak fitting. 60 The center frequency of the vibrational characteristic peak of the local polariton dipole group within the carbon cage; We summarized inelastic neutron scattering and terahertz time-domain spectral data, performed baseline calibration and normalization on the two sets of frequency domain data, and calculated the absolute difference between lattice transport frequency and local vibration frequency in different materials.

[0050] Table 1. Test data of characteristic frequencies and resonance offsets for each embodiment and comparative example. Based on the data in Table 1, the present invention proposes to achieve [the desired effect] through spatial gradient construction and intrinsic stress frequency modulation. The physical mechanism of the =0 rigidity condition has been empirically verified; the absolute frequency difference in Examples 1 to 4 is less than 0.1 THz, and the electron transport frequency of the skeleton lattice and the vibration center frequency of the local polaron are highly coincident around 50 THz; this result verifies that the broadband constructed by the isotope gradient, after being subjected to precise lattice extrusion by localized alkali metal vapor intercalation, effectively achieves macroscopic frequency alignment, providing a zero-phase-difference transmission channel for the mirror resonance coupling between electrons and local polarons.

[0051] The comparative test results reveal the necessity of each specific process step in meeting the superconducting coherence threshold; in Comparative Example 1, the graphylene template was removed, and pure C was used. 18 The network underwent structural collapse at room temperature, and its skeleton characteristic frequency decreased significantly to 22.14 THz, proving that the in-situ template solidification process is the basis for maintaining the high-frequency rigid transmission of the carbon-based skeleton. Comparative Example 2 did not use isotope microfluidic gradient, resulting in the system having only a single high-frequency vibration around 90 THz, completely deviating from the 50 THz resonance capture window, indicating that establishing a continuous characteristic frequency band is a prerequisite for achieving subsequent frequency modulation.

[0052] Comparative Examples 3 and 4 verified the crucial role of liquid-phase lock-in technology in overcoming thermal fluctuation terms. In Comparative Example 3, electric field polarization was applied after solid-state molding. Due to the Faraday cage effect of the highly conductive network, the dipoles could not be effectively aligned, resulting in a wide range of disordered vibration frequencies. In Comparative Example 4, only electric field polarization was applied without ultraviolet light crosslinking. The internal dipoles under room temperature thermal excitation underwent random flipping relaxation, with a frequency shift of 11.48 THz, confirming that photochemical locking of the spatial geometry is the core condition for maintaining the self-sustaining microscopic quantum state. Comparative Example 5 omitted the gas-phase localized intercalation process. The test results showed a fixed deviation of 8.72 THz between the lattice frequency and the dipole frequency, indicating that the lack of isotropic chemical stress compression generated by alkali metal atoms prevented the macroscopic frequency band from completing the final compression towards the resonance red line. Consequently, the system could not fall into the dissipationless quantum coherence region of less than 2.

[0053] Test Example 2 provides a comprehensive dielectric-specific heat testing method for polarization dipole self-sustainability and elimination of thermal fluctuation terms. The specific test steps are as follows: The terminal composite material powders obtained in each embodiment and comparative example were pressed into discs with a diameter of 8 mm and a thickness of 0.5 mm in a glove box filled with high-purity argon gas; a gold electrode layer with a thickness of 50 nm was sputtered on both the upper and lower surfaces of the discs using a vacuum coating machine to form a dielectric test structure. The test sheet with gold electrodes was fixed inside the variable-temperature sample stage of a broadband electrodeless dielectric spectrometer; at 10 - 6 Under a Torr vacuum environment, the test AC frequency was set to 1MHz, and the temperature was continuously scanned from 4K to 400K at a temperature change rate of 2K / min. The continuous spectrum of the dielectric loss tangent tanδ as a function of temperature was recorded and extracted to obtain the maximum loss data of the broadened relaxation peak in the room temperature region. Separately, the material powder was pressed into 2mg micro cubes, which were then attached to the specific heat capacity testing calorimeter block of the physical property measurement system using thermally conductive silicone grease. In an adiabatic high-vacuum environment, the temperature was scanned from 2K to 100K using the thermal relaxation method, and the specific heat capacity C was recorded. p Continuous data; converting data to C++p / T3C p The relationship curve between / T3 and temperature TT was used to calculate the peak intensity of the boson peak corresponding to the lattice soft mode in the low-frequency region.

[0054] Table 2. Test data of dielectric loss and low-temperature specific heat capacity characteristic parameters for each embodiment and comparative example. Based on the data in Table 2, this invention proposes a mechanism to isolate room temperature thermal fluctuations and satisfy the absolute physical boundary Γ=0 by using a rigid lattice and spatial configuration phase-locked loop, obtaining macroscopic thermodynamic and electrical empirical evidence; the maximum dielectric loss tangent of Examples 1 to 4 is maintained at 1.5×10 in the room temperature region. -3 The following extremely low levels, and the absence of obvious boson peaks in the specific heat capacity test at low temperatures, confirm that graphyne-C 18 The extremely high carbon-carbon bond tension of the heterogeneous network completely eliminates the low-frequency phonon soft mode. At the same time, the spatial orientation of the confined polarized molecules has been rigidly solidified by photochemical microcovalent bonds, cutting off the dipole reversal and lattice scattering dissipation channels under room temperature thermal excitation.

[0055] The comparative data visually expose the core role of each specific process in maintaining system coherence; Comparative Example 1 lacks a graphylene framework template and uses pure C. 18 The network could not maintain its internal tension, producing a significant boson peak of 5.31 mJ, indicating the presence of a strong low-frequency phonon soft mode. The sharp increase in the Γ term disrupted the pairing environment. Comparative Example 3 failed to achieve polarization alignment due to being trapped in the solid-state Faraday shielding effect, exhibiting a peak of 41.33 × 10⁻⁶ mJ. -3 The low dielectric loss indicates that the dipoles inside the cage are in a disordered state; although Comparative Example 4 underwent liquid-phase polarization but not UV-crosslinking phase-locking, its room-temperature dielectric loss soared to 115.48 × 10⁻⁶. -3 The data confirms that in a macroscopic room temperature thermal reservoir, dipoles that have not been chemically bonded undergo violent thermal fluctuations and initiate polarization decoherence. The test results of this invention verify that the process design combining ultraviolet photoelectric phase-locking with a high-tension framework is the only feasible path to force the long-term self-sustaining of microscopic quantum asymmetry in room temperature macroscopic materials.

[0056] Test Example 3 provides a test method for macroscopic superconducting electrical properties and resistivity under varying temperatures at ambient pressure. The specific test steps are as follows: In a glove box protected by high-purity nitrogen, the terminal composite material powders obtained in each embodiment and comparative example were placed in a mold and cold-pressed under a constant pressure of 20MPa to form a dense strip-shaped test sample with a length of 10mm, a width of 2mm, and a thickness of 1mm. The standard four-probe wiring method was used. Four platinum leads with a diameter of 50μm were fixed at equal intervals on the sample surface using highly conductive pure silver conductive paste. The lead spacing was controlled to be 2mm. The sample with the leads connected was placed in a vacuum desiccator to cure the silver paste for 12 hours to reduce the contact resistance. The cured test sample was mounted on the variable temperature sample Torr holder of the integrated physical property measurement system equipped with a high temperature option, ensuring stable electrical connection of the four terminals; and a normal pressure high-purity helium environment of 1 atm was maintained in the test chamber as the heat conduction medium. The DC excitation current was set to 1mA, and the system continuously and slowly scanned the temperature from 4K to 400K at a temperature change rate of 1K / min. The potential difference between the two voltage terminals of the sample was continuously recorded in real time using a nanovoltmeter, and the corresponding resistivity data was calculated. The initial transition temperature at which the resistivity began to deviate from the normal temperature response and the zero resistance temperature at which the resistivity dropped sharply to the instrument noise floor were recorded.

[0057] Table 3. Test data of resistivity characteristic parameters under ambient pressure and varying temperature for each embodiment and comparative example. According to the data in Table 3, the macroscopic quantum coherent state based on generalized operator dynamics constructed in this invention exhibits clear room-temperature superconducting properties in electrical transport. Examples 1 to 4 all have zero-resistance temperatures consistently above 300 K under ambient pressure, and their resistivity at the 300 K room-temperature test node is below the physical limit of the measuring instrument. This macroscopic electrical performance directly confirms that, in a room-temperature heat storage environment, the microfluidic spatial gradient construction and gas-phase intercalation intrinsic stress compression mechanism successfully and accurately locked the [quantum coherent state]. The rigid physical coherence conditions enabled polariton-assisted phase difference-free electron transport and lossless condensation.

[0058] Comparative test data confirmed the decisive influence of various specific process steps on crossing the room temperature superconductivity threshold; Comparative Example 1, due to the lack of a graphdiyne framework template structure, exhibited a resistivity as high as 5.24 × 10⁻⁶ at 300 K. 3 Ω⋅cm, exhibiting typical insulator characteristics, confirming that it is pure C. 18 Two-dimensional networks undergo topological collapse at room temperature, losing their electron travel channels. Comparative Example 2, which did not perform isotopic microfluidic gradient titration, exhibits a conventional metallic conductive state without any superconducting phase transition, indicating that the frequency of a single molecule is out of the fault-tolerant window formed by the broadening of component isotopes, making it extremely difficult to directly hit the 50 THz electron resonance singularity on a macroscopic scale. Comparative Example 3 omits the spatial rotational electric field polarization in the liquid phase state of the insulating precursor. The dipoles are hindered by the Faraday electrostatic shielding effect of the highly conductive carbon network, failing to achieve ordered alignment. The internal vibrational frequencies are discrete, and the system remains in the conventional conductor range.

[0059] Comparative Examples 4 and 5 showed signs of mid-to-low temperature superconductivity but completely lost room-temperature superconductivity. Comparative Example 4 lacked in-situ deep ultraviolet phase-locking technology, and the spatial configuration of the polarized dipoles within the cage was not rigidly constrained by micro-covalent bonds. As the temperature increased, strong room-temperature thermal fluctuations easily broke down the directional arrangement of the polarized dipoles, and the depolarization effect caused the thermal fluctuation term Γ≠0, resulting in the collapse of the electronic coherent state at 134.1 K. Comparative Example 5 completed the construction of microfluidic gradients and photoelectric phase-locking, but lacked gas-phase localized intercalation of alkali metal atoms, and the isotropic chemical compression stress required to approach the singularity was not generated inside the lattice. The broadband constructed in the early stage could not achieve the final elastic compression towards the resonance red line, and there was a residual deviation between the micro-polaron frequency and the lattice frequency, which led to increased energy dissipation of the system and the zero-resistance temperature was suppressed at 212.5 K. The above comparisons rigorously demonstrate that the process closed loop of the present invention is the only sufficient condition for forcing the system to fall into the coherent region and maintain the room-temperature superconducting state.

[0060] Test Example 4 provides a test method for superconducting magnetic properties and perfect diamagnetism. The specific test steps are as follows: The terminal composite material powders obtained in each embodiment and comparative example were loaded into standard non-magnetic gelatin capsules, compacted, and fixed to the inside of non-magnetic plastic pipettes. The sample loading and fixing operations were completed in a glove box filled with high-purity helium to avoid interference from the weak magnetic signal caused by the adsorption of paramagnetic oxygen molecules. A plastic pipette containing the sample is attached to the sample probe of the superconducting quantum interference device and lowered into the system's measurement chamber; the measurement chamber is evacuated and filled with low-pressure, high-purity helium to maintain heat exchange; The system is set to enter zero magnetic field cooling measurement mode; under zero external magnetic field conditions, the sample is cooled from 350K to 4K at a cooling rate of 5K / min; after the temperature stabilizes, a DC external test magnetic field with an intensity of 50Oe is applied; while keeping the test magnetic field constant, the temperature is continuously and slowly increased to 400K at a rate of 2K / min, and the change in magnetic moment of the sample during the heating process is recorded in real time using a high-sensitivity detection coil to extract the zero magnetic field cooling magnetic susceptibility data; The system is set to enter field cooling measurement mode; the 50 Oe DC external test magnetic field is kept in place, and the sample is slowly cooled from 400 K to 4 K at a rate of 2 K / min. The magnetic moment response of the sample during the cooling process under a constant external magnetic field is recorded in real time, and the field cooling magnetic susceptibility data is extracted. Combined with the apparent density and geometric dimensions of the sample, the measured macroscopic magnetic moment data is converted into dimensionless volume magnetic susceptibility parameters, and then substituted into the calculation to obtain the superphase volume fraction.

[0061] Table 4. Room temperature volumetric magnetic susceptibility and superphase volume fraction test data for each embodiment and comparative example. According to the data in Table 4, the carbon-based structure constructed by the present invention through insulating microfluidic self-assembly and deep ultraviolet electromagnetic phase transition phase-locked loop (LELPL) exhibits a macroscopic Meissner effect at room temperature, verifying the dissipationless antimagnetic repulsion characteristic derived from the generalized operator dynamics mechanism from the perspective of intrinsic magnetic properties. The zero-magnetic-field cooling volume magnetic susceptibility of Examples 1 to 4 at 300 K all reached above -0.88, and the calculated superphase volume fraction reached a maximum of 95.7%. This extremely strong antimagnetic repulsion signal completely eliminates the false resistance decrease caused by interfacial metal phase transitions or conductive network reconstruction, confirming the precise locking effect caused by the coupling of continuous isotope broadening and intrinsic chemical stress. The conditions were indeed met, establishing a macroscopic quantum coherent state that resisted magnetic flux penetration within the three-dimensional bulk space of the material.

[0062] Comparative data from different compositions and processes reveal the boundary constraints that maintain the polarization coherence mechanism in a room-temperature macroscopic thermal reservoir; Comparative Example 1 exhibits a typical weak paramagnetic background, confirming that pure C is freed from the strong support of the graphdiyne lattice. 18 The network underwent disordered collapse, and the effective coupling channels between electrons and the lattice disappeared; Comparative Examples 2 and 3 only measured extremely weak normal diamagnetic background signals at 300 K, with the volume magnetic susceptibility remaining at 10. −4 Up to 10 −5 The magnitude indicates that without bandwidth broadening or Faraday shielding to block dipole alignment, the system cannot statistically approach the resonance singularity and cannot induce Cooper pair condensation. Comparative Examples 4 and 5 completely lost their bulk antimagnetic repulsion capability at room temperature, with magnetic flux lines completely penetrating the material bulk. This confirms that if microscopic dipoles are not rigidly anchored by photochemical crosslinking bonds, strong room temperature thermal fluctuations will immediately destroy the configuration symmetry. Similarly, without the isotropic compressive stress imparted by the vapor intercalation of alkali metal atoms, the previously established bandwidth cannot achieve elastic approximation to the 50 THz red line. The residual microscopic frequency difference eventually leads to the decoherence and disintegration of the coherent state at room temperature, causing the Meissner phase transition threshold to drop significantly below room temperature.

[0063] Test Example 5 provides a method for testing the long-term aging and environmental tolerance of terminal composite materials under normal temperature and pressure atmospheric conditions. The specific test steps are as follows: The terminal composite material powder prepared in Example 1 was placed in an open quartz petri dish and placed in a constant temperature and humidity test chamber. The ambient temperature was set to 298K and the relative humidity to 45%, simulating a normal atmospheric exposure environment, and subjected to unprotected exposure aging for 90 days. Random samples were taken from the petri dishes on days 0, 15, 30, 60 and 90 of the exposure period, and the sample size had to meet the standard requirements for a single electrical and magnetic test. According to the standard four-probe method described in Test Example 3, the resistivity of the sampled powder at each time point was tested under normal pressure and temperature variation. The initial transition temperature at which the resistivity of each sample suddenly dropped and the zero resistance temperature at which the resistivity dropped to the bottom line of the instrument were recorded. Following the magnetic testing procedure described in Test Example 4, a superconducting quantum interference device was used to test the sampled powder at each time point in a zero magnetic field cooling mode, and the macroscopic volume magnetic susceptibility data of the sample at a temperature of 300K was extracted and recorded.

[0064] Table 5. Test data on the evolution of superconducting characteristic parameters of the material in Example 1 under 90 days of atmospheric exposure. According to the data in Table 5, the carbon-based composite material prepared by this invention exhibits macroscopic thermodynamic and chemical stability under normal atmospheric humidity and room temperature exposure, and its built-in quantum coherent state does not undergo decoherence decay over time; after being placed in an unprotected open environment for 90 consecutive days, the zero-resistance temperature of the sample in Example 1 was maintained at 315.1 K, and the magnetic susceptibility of the zero magnetic field cooled at 300 K remained in the strong diamagnetic range of -0.933; the slight fluctuations in parameters during the test period were normal thermodynamic disturbances caused by baseline drift of the measuring instrument and surface physical adsorption, and the superconducting phase transition threshold and Meissner state repulsion volume were not substantially affected.

[0065] The test results directly confirmed the effectiveness of the specific process of this invention in overcoming the decoherence effect; the micro-covalent network established by in-situ crosslinking under deep ultraviolet light provides a rigid spatial constraint, transforming the dipole configuration of polarized molecules endowed by the rotating vector electric field into a permanent chemical phase lock; this phase lock mechanism makes the polarized molecule group within the cage immune to long-term room temperature thermal fluctuation disturbances, maintaining a local zero-fluctuation physical boundary in the macroscopic thermal reservoir; the external three-dimensional porous graphdiyne network and the dense aromatic electron cloud of the fullerene carbon cage construct a physical and chemical shielding layer, blocking the permeation paths of oxygen and water molecules in the atmosphere, and protecting the locally intercalated rubidium metal atoms from oxidation; the system continuously satisfies the mathematical rigidity condition of absolute alignment between the transit frequency of the itinerant electrons and the vibration frequency of the local polarons in the generalized operator dynamics, locking the coherence interval, and verifying the intrinsic self-sustaining capability of this room temperature superconducting material in a real normalized engineering environment.
