The application multiplexes the bottom principles of three generations of self-developed technologies, time-sharing switches liquid phase pH: weak acid (pH 5.0-6.0) to prepare amino acid functional nets, strong acid (pH 2.0-3.0) to prepare alkaloid radiation quenching films, solves the problem that the two types of molecular physical and chemical properties are incompatible, and the finished product can still be stably served after being separated from the liquid phase.

Description

Technical Field

[0001] This invention relates to the preparation technology of high radiation protection composite materials for deep space aerospace, the graded purification technology of natural biomolecule electric fields, the time-controlled two-dimensional molecular weaving technology with multiple pH ranges, the micro-nano electric field single-molecule directional arrangement molding technology, the gradient quantization composite film stacking processing technology, the modular mass production process of large-area flexible protective materials, and the application technology of molecular-level in-situ self-healing in space. Specifically, it is a time-variable pH twenty-seven-layer gradient stacked deep space anti-radiation biocomposite armor with clearly defined components, quantified process parameters, and scientific deduction of the full-level structure. Background Technology

[0002] Currently, the traditional radiation protection materials used in deep spacecraft and deep space exploration equipment are mainly metal alloys, inorganic ceramic plates, and rigid polymer protective materials. These traditional protective materials have many inherent shortcomings and limitations in practical applications. First, traditional rigid protective materials are heavy, which does not meet the core requirements of lightweight design for aerospace equipment. At the same time, their surface-fitting performance is poor, making them unsuitable for irregularly shaped cabins, curved outer walls, and flexible protection scenarios. Second, the radiation protection coverage of traditional protective materials is relatively limited, only able to achieve simple physical shielding against some ultra-high-energy macroscopic particles. They cannot effectively dissipate kinetic energy or quench energy for secondary neutrons, scattered gamma rays, ionized debris generated by radiation ionization, chain-like reactive oxygen free radicals, and ultra-low-energy residual penetrating particles that are common in the deep space environment.

[0003] In addition, traditional protective materials are exposed to the vacuum environment of space, extreme temperature changes of ±120 degrees Celsius, and continuous high-energy particle bombardment for a long time. They are prone to problems such as internal lattice defects, surface cracking and peeling, and gradual decline in protective performance. Their overall service life is relatively short, and the cost of maintenance and replacement is high. They cannot meet the protection requirements for long-term deep space voyages and stable on-orbit operation.

[0004] Currently available bio-based protective film manufacturing processes also suffer from significant technical defects: First, the molding and preparation environment is singular and lacks differentiation between the inherent dissociation pH adaptation ranges of L-amino acids and alkaloids during the research and design phase. The use of mixed-phase molding methods easily leads to imbalances in molecular charge states, disordered spatial arrangement, and mutual interference between functional layers. Second, the design of multilayer composite structures is highly subjective and arbitrary, failing to incorporate the distribution law of cosmic particle energy spectrum gradients and molecular electrical adaptation parameters for hierarchical arrangement design. This results in high overall structural redundancy and numerous blind spots in protection. Third, the overall process parameters are poorly recorded, lacking standardized electric field control parameters, microscopic arrangement density parameters, and single-layer thickness control indicators. The design remains at the theoretical stacking design level and lacks the conditions for industrial-scale reproducible manufacturing.

[0005] L-amino acids and alkaloids, two core functional molecules, have fundamentally different physicochemical stability ranges. L-amino acids can only maintain their normal electronic state under weakly acidic preparation environments, while alkaloids can only maintain stable dissociation activity under specific acidic preparation environments. These two types of molecules cannot share the same liquid-phase molding system. Furthermore, the aforementioned acidic conditions are specific to the molding process; the finished product can function stably without relying on corresponding acid or alkaline environments after curing. Existing conventional preparation processes have not recognized the core necessity of time-switching environments and segmented weaving molding, consistently using a single static liquid-phase environment for film formation. This results in protective films with a loose structure, prone to embrittlement and cracking, and significantly reduced long-term protective stability. Addressing the gaps and inherent defects in existing technologies, this invention relies on a self-developed third-generation complete electric field technology system, a unique time-switching dynamic pH-switching weaving process, and a 27-layer fully defined molecular gradient protective structure. It also supplements a complete set of quantitative process parameters and a theoretical protective attenuation model, perfecting the entire technology loop. Summary of the Invention

[0006] 1. Self-developed three-generation core technology system: The first-generation two-stage precise separation and purification technology for 38 amino acids: This technology's proprietary stable operating system is set in a weakly acidic liquid phase preparation environment with a pH of 5.0–6.0. ​​Within this stable and suitable pH range, various mixed amino acids can achieve uniform and controllable electronification, allowing each amino acid molecule to form its own unique intrinsic net charge. After the equipment is turned on with a constant directional electric field, all amino acid molecules uniformly follow a fixed directional migration trajectory from right to left. During the research and development process, the differences in intrinsic charge, molecular spatial polarity, and chiral resolution adaptation properties between different amino acids are utilized to enable various L-amino acids to form distinctly differentiated migration rates and steady-state residence ranges. This technology employs a two-stage separation architecture for stepwise purification. The first stage is a coarse classification, dividing the mixed amino acid raw materials into six categories: acidic L-amino acids, acidic D-amino acids, basic L-amino acids, basic D-amino acids, neutral L-amino acids, and neutral D-amino acids. This completes the interception and pretreatment of these major categories. The second stage is a fine classification, which, based on the six major categories, performs a second precise separation based on differences in electrical properties. Ultimately, 38 different amino acids (including L-amino acids) are stably enriched in their respective 38 independent and dedicated regions. Combined with the upper contrast solution targeted spray elution structure, the enriched high-purity amino acids (including L-amino acids) are guided to the lower dedicated collection pipeline, completing the targeted high-purity uptake of all 38 amino acids (including L-amino acids) in one go. This provides compliant, stable, and high-purity raw materials for the preparation of all L-amino acid functional layers of this invention. This weakly acidic environment is only for raw material purification and weaving. After the two-dimensional functional network is solidified, the L-amino acid molecular arrangement and charge capture efficiency are permanently locked, making it suitable for the neutral vacuum service environment in space.

[0007] The second-generation universal single-stage separation and purification technology for traditional Chinese medicine alkaloids: This technology features a dedicated stable operating system set in a strongly acidic liquid phase preparation environment with a pH of 2.0–3.0. The core difference between this technology and the first-generation amino acid separation technology lies in its simplified single-stage sorting architecture, perfectly suited to the self-dissociation characteristics of small alkaloid molecules. It eliminates the need for a two-stage separation structure, resulting in a more streamlined and efficient overall process. Within the stable acidic pH range of 2.0–3.0, various traditional Chinese medicine alkaloids exhibit stable differential dissociation and charging effects. The inherent charge, conjugated planar structure, and motion damping coefficients of different alkaloids provide natural differentiation. Under the applied directional constant electric field, the movement trajectories and steady-state positions of various alkaloids are autonomously separated. Combined with a continuous rinsing and elution process using a contrast agent, the efficient purification and enrichment of multiple alkaloids can be achieved through a single-stage sorting chamber, providing dedicated high-purity raw material support for the radiation quenching functional layers of this invention. This strongly acidic condition is only applicable to the preparation and sorting stage. After the alkaloid film solidifies, the conjugated framework structure is locked, and it can maintain its radiation quenching performance for a long time even after being removed from the acidic liquid phase. The third-generation micro-electric field XY coordinate two-dimensional biomolecular weaving principle: In practical applications, this invention only utilizes the three core underlying process capabilities of the third-generation technology: precise XY grid coordinate addressing and positioning function, micro-nano electric field single-molecule directional migration regulation function, and micro-field induced orderly molecular arrangement and association function. It explicitly avoids any nucleotide synthesis-related operations, and expands this precise molecular manipulation technology to the field of two-dimensional planar weaving of L-amino acids and alkaloids, enabling each single-category molecule to be independently woven into a dense and uniform two-dimensional biofunctional network.

[0008] 2. The core originality of this invention: Time-sharing dynamic pH switching weaving process: The physical dissociation stability ranges of L-amino acids and alkaloids are inherently incompatible, which is the core theoretical basis for the necessity of using a time-sharing switching process in this invention.

[0009] First, L-amino acid molecules can maintain a stable electronically charged state only within a weakly acidic preparation environment of pH 5.0 to 6.0, with controllable migration trajectories, and can be regularly woven into a dense two-dimensional functional network. Once deviated from this suitable pH range, it will only affect the film-forming effect during the preparation stage. The L-amino acid functional network after solidification will not experience charge imbalance or disordered arrangement under neutral and vacuum conditions in space, and its protective performance will not be affected by external acid or alkaline environments.

[0010] Second, alkaloid molecules can maintain a stable state of differential dissociation only in a specific preparation environment with a strong acidity of pH 2.0 to 3.0, and their own conjugated molecular structure remains intact, allowing them to complete the film formation process in an orderly manner. Deviation from the suitable range only affects the forming process. After the finished film is shaped, the molecular structure is stable and solidified, and it can stably perform the radiation quenching function in the conventional space service environment without losing its inherent function.

[0011] Based on the above objective physical and chemical characteristics, this invention adopts a time-division, segmented, and replacement-based exclusive weaving logic: First, when preparing any type of L-amino acid two-dimensional functional network, the sealed weaving cavity is strictly locked with a weakly acidic environment of pH 5.0–6.0, and the electric field parameters are calibrated under constant temperature and voltage to complete the warp and weft weaving and curing of a single molecular network; Second, after the single-layer L-amino acid network is completely cured and the structure is stable, the original liquid phase medium inside the cavity is emptied, the cavity is cleaned and the environment is replaced, the equipment parameters are readjusted, and the system is switched to an acidic exclusive system of pH 2.0–3.0; Third, in the newly adapted environment, a corresponding combination of alkaloid two-dimensional quenching network is prepared, and after the single-layer curing is completed, the environment switching and the next set of molecular weaving operations are repeated.

[0012] The entire process follows a step-by-step operation mode with different time periods, different liquid media, different pH parameters, and different electric field settings. This is the time-varying pH two-dimensional weaving process described in this patent. This is a necessary process prerequisite for the two types of alternating molecules to form a stable film, maintain long-term structural integrity, and prevent the degradation of protective performance. It is also the core originality of this invention, which distinguishes it from all static single-environment molding solutions in the industry.

[0013] 3. Quantitative process parameters for this invention: Weaving environment parameters: L-amino acid weaving environment pH 5.0–6.0, constant temperature control 22℃–26℃; alkaloid weaving environment pH 2.0–3.0, constant temperature control 22℃–26℃; electromagnetic shielding strength of the entire weaving cavity is not less than 45dB. All parameters are specific control conditions for the preparation stage. Electric field control parameters: Controllable voltage adjustment range for the entire weaving process 12V–36V, which can be finely adjusted in real time according to different molecular migration characteristics, used for molecular orientation arrangement during the molding stage. Microstructure parameters: The thickness of the single-layer biomolecular functional network is controlled between 80nm and 160nm; the molecular warp and weft arrangement density is controlled at 1.2×10⁻⁶. 7 ~2.0×10 7Molecular units per square centimeter; interlayer composite gaps are no greater than 50 nm, ensuring no voids or microscopic leakage channels. Protection attenuation model: The overall model follows a five-level progressive attenuation law: physical scattering deceleration, charged particle capture, neutron moderation dissipation, radiation and free radical quenching, and ultra-low energy residual bottom-up adsorption. The radiation energy levels from the outer layer to the inner layer are derived from Monte Carlo simulations of typical deep-space particle energy spectra (such as protons, neutrons, and gamma rays), decreasing by 12%–18% layer by layer. This range represents the theoretically optimal value; in actual industrial production, reasonable fine-tuning can be made according to membrane thickness and application scenarios. Interlayer bonding parameters: After the functional layers are solidified and stacked, physical association is achieved through intermolecular hydrogen bonds and weak van der Waals interactions, without chemical covalent cross-linking, balancing structural stability and membrane flexibility.

[0014] 4. Complete Components, Hierarchical Positioning, and Scientific Deduction Logic of the Twenty-Seven Layers: Rigid Premise of Overall Design: All molecules used in this invention have undergone preliminary screening and optimization, thoroughly eliminating ineffective components, functionally overlapping components, acid-base incompatible components, and energy level conflicting components, ensuring that each layer has a specific function and is not redundant; glycine has no chiral carbon structure and is not labeled with the L-prefix, while other chiral amino acids uniformly adopt the L-type configuration, conforming to the distribution pattern of interstellar natural amino acids. The overall arrangement strictly follows the principle of starting with the outer graphene hard barrier, with the main region fixed according to the odd-even alternation rule of L-amino acid → alkaloid → L-amino acid → alkaloid, and molecules of the same type are not stacked continuously to avoid the creation of protection blind spots due to electric field homogenization. Energy level gradient distribution principle: The outermost layer undertakes the task of intercepting ultra-high energy heavy ions and primordial cosmic rays, adapting to high-energy particles, medium-energy particles, low-energy particles, secondary neutrons, gamma rays, and various free radicals in sequence inwards, and the innermost layer is specially designed to catch ultra-low energy residual particles. The molding and weaving adaptation standards are unified: the molding standard for L-amino acid functional layer is pH 5.0-6.0, and the molding standard for alkaloid functional layer is pH 2.0-3.0. The entire process adopts a time-segmented switching environment and segmented independent molding mode; the finished product does not depend on the above acid and alkaline conditions for service.

[0015] The overall design has a total of 27 layers: layers 1 and 2 are graphene hard front barrier layers, layers 3 to 26 are twelve groups of alternating L-amino acids and alkaloids core protective layers, and layer 27 is the inner terminal arginine self-repairing bottom layer.

[0016] Part 1: Outer Rigid Pre-Barrier (Layers 1-2): Layer 1: High-Density Multilayer Graphene Arrangement: As the outermost first physical barrier of the entire protective armor, it directly faces the highest-energy heavy ions and primordial high-energy protons incident from deep space. Relying on the carbon-based dense lattice structure, it achieves Coulomb scattering and significant reduction of initial kinetic energy, preferentially reducing the penetration intensity of high-energy particles and mitigating the impact load on subsequent biological functional layers. Main function: To achieve primary physical interception and initial deceleration scattering of ultra-high-energy heavy ions and primordial cosmic rays.

[0017] Layer 2: Lightly Oxide Graphene Transition Layer: Layout and Deduction: Primarily used to connect the rigid carbon-based barrier with the inner biomolecular functional regions, effectively mitigating interfacial stress between different materials, stabilizing the surface micro-electric field distribution, and preventing structural problems such as material interface delamination and electric field distortion; simultaneously, it performs secondary weakening of residual high-energy particles penetrating the first layer, smoothly guiding particles into the subsequent biological protection area. Main functions: Interfacial voltage stabilization and transition, interlayer adaptation of different materials, and secondary deceleration and weakening of residual high-energy particles.

[0018] Part Two: The Core 12 Alternating Protective Layers (Layers 3-26, decreasing in energy from high to low): Layer 1 is adapted for extremely high-energy protons and residual helium nuclei. Layer 3: L-aspartic acid is used, relying on its strong negative charge configuration to precisely capture high-energy bare charged ions that have just penetrated the graphene barrier, locking highly penetrating particles and preventing deep penetration. Layer 4: Berberine is used, and during the preparation stage, stable dissociation and ordered film formation are completed in a strongly acidic environment of pH 2.0-3.0; after solidification and shaping, the conjugated molecular framework is locked, which can instantly quench the primary free radicals generated by high-energy particle collisions under neutral conditions in space, completely cutting off the radiation chain reaction extension path. Deductive Logic: When particles first enter the biological protection area, their charge is strongest and their energy level peak is highest. First, the strong negative charge L-amino acid completes the site-specific core locking, and simultaneously, highly conjugated alkaloids treat free radicals, forming a closed-loop energy control structure.

[0019] Group 2 is adapted for heavy-mass, high-energy heavy-ion residues: Layer 5: L-glutamic acid is used to expand the internal hydrogen bond damping network, significantly consuming the inertial kinetic energy of the heavy-mass ions and reducing their directional penetration ability. Layer 6: Matrine is used, exhibiting excellent film-forming stability only in the acidic environment of pH 2.0–3.0 during preparation; after solidification, the structure no longer depends on the acidic system and can effectively scatter medium- and high-energy rays in the space service environment, dispersing the residual momentum of heavy-ion motion. Reasoning: Heavy ions have large mass and strong inertia; high-damping L-amino acids are used for slowing down the process, and stable alkaloids disrupt the directional motion trajectory of particles, eliminating the risk of hard breakdown.

[0020] The third group of proton beams adapted for medium-energy space travel: Layer 7: L-serine is used, with its surface enriched with polar adsorption sites to confine and lock medium-energy protons, constraining their disordered trajectories. Layer 8: Berberine is used, achieving stable arrangement under acidic conditions during preparation. After solidification, its highly enriched π-electron cloud in conventional space environments can smoothly and continuously dissipate the internal kinetic energy of medium-energy particles, steadily lowering the incident energy level. Theoretical logic: Medium-energy particles have long endurance and a stable penetration process. Polar L-amino acids are used to confine their trajectories, combined with conjugated electron layers to achieve gradual energy consumption.

[0021] Group 4 is suitable for primary and secondary neutrons and neutral, charge-free particles: Layer 9: L-threonine is used, relying on its own hydroxyl functional group to enhance the neutron slowing effect and reduce the overall velocity of neutral neutrons. Layer 10: Corydaline is used, its unique heterocyclic molecular structure is permanently retained after forming, and it can accurately adsorb secondary micro-fragments generated by neutron fragmentation, blocking the diffusion of neutron-derived radiation. Logical reasoning: Neutrons are uncharged and cannot be captured by an electric field; they can only be slowed down by the physical damping of hydroxyl groups, and then fragment capture is achieved through the heterocyclic structure.

[0022] Group 5 is adapted for high-energy gamma-ray scattering residues and ionized fragments: Layer 11: L-cysteine ​​is selected to complex free fragments generated by radiation ionization through its thiol structure, while simultaneously initiating initial repair of microscopic defects. Layer 12: Chelidonium red alkaloid is selected, possessing inherent natural anti-ionizing radiation properties. After molding, it does not require an acidic environment and can effectively neutralize residual gamma-ray ionization energy, inhibiting the inward diffusion of ionized fragments. Logical reasoning: Gamma rays readily generate a large number of free ionized fragments. First, L-amino acids are used to fix the fragment body, and then a special alkaloid is used to neutralize the remaining radiation energy, thus controlling radiation hazards in both directions.

[0023] Group 6 is adapted to medium-energy electron beams and secondary derived scattered rays: Layer 13: Glycine is selected; its small molecular structure allows for dense filling, sealing nanoscale microscopic penetration gaps and preventing leakage of small particles. Layer 14: Papaverine is selected; its flexible conjugated molecular structure provides stable performance after formation, specifically dissipating the disordered kinetic energy of scattered electrons and smoothing out chaotic electron flow. Logical reasoning: Electron beams are extremely small in size and easily penetrate microscopic gaps, creating leaks. The small molecule glycine fills the protective blind spots, and the flexible molecule absorbs the scattered energy.

[0024] Group 7, adapted for low-energy heavy ion fragmentation of small micro-fragments: Layer 15: L-alanine is used, with a regular molecular lattice arrangement to construct a stable low-energy directional protective barrier, preventing fragments from diffusing and spreading inward. Layer 16: Sophora tonkinensis alkaloid is used, achieving ordered film formation only in an acidic preparation system. After solidification, the molecular structure is stable and reliable, independent of external acid and alkaline conditions, and can firmly lock low-energy fragment ions, constraining the overall diffusion range. Logical reasoning: Low-energy fragments are numerous and highly dispersed, relying on a regular lattice to achieve physical containment, combined with stable alkaloids to solidify residual microparticles.

[0025] Group 8 is suitable for slow-release neutrons and thermal neutrons: Layer 17: L-valine is used, and its hydrophobic network structure traps low-velocity slow neutrons, extending the particle's residence and dissipation time and improving energy absorption efficiency. Layer 18: Strychnine is used; its inherent protective properties are retained after the fused-ring macromolecular structure is formed, deeply absorbing the remaining neutron energy and completely eliminating the safety hazards of slow neutrons. Logical reasoning: Slow neutrons move slowly and have a long residence time inside the chamber; the hydrophobic layer extends the dissipation path, and the fused-ring structure completes the final energy absorption.

[0026] Group 9 is adapted to radiation-induced reactive oxygen species and chain free radical clusters: Layer 19: L-leucine is selected to seal the microscopic defects and pores of the membrane itself, blocking all pathways for free radicals to penetrate deeper into the membrane. Layer 20: Evodia rutaecarpa is selected, which has strong antioxidant activity. After molding, its functional properties are not affected by the pH of the environment. It can quench reactive oxygen species in batches, terminating the continuous spread of oxidation chain reactions. Theoretical logic: When the free radical concentration reaches its peak in the later stages of protection, defects are first sealed to prevent infiltration, and then batch quenching is completed in a concentrated manner.

[0027] Group 10 is adapted for weakly ionized ultra-low-energy residual particles: Layer 21: L-isoleucine is selected, with a special isomer arrangement to fill irregular microscopic protection blind spots and fill tiny interception blind areas. Layer 22: Tetrandrine is selected, with stable performance after the long-chain conjugated structure is formed, neutralizing the residual energy of low- and medium-energy radiation, and completing the final protection in the low-energy region. Reasoning: Low-energy particles are highly concealed and prone to leakage. Isomeric L-amino acids are used to fill blind spots, and long-chain molecules complete the end-energy dissipation.

[0028] Group 11 adapts to interlayer interface disturbance particles and weakly charged particles with electric field imbalance: Layer 23: L-histidine is selected; its imidazole ring structure can multifunctionally adsorb various residual weakly charged particles, stabilizing the micro-electric field balance at the interlayer interface. Layer 24: Fritillaria cirrhosae is selected, employing a mild, low-energy-dissipation mode to buffer the pressure load on the inner protective structure and protect the overall structure at the rear end from progressive breakdown. Reasoning: The electric field near the inner region is prone to fluctuations; multifunctional L-amino acids stabilize and bind particles, while mild alkaloids provide pressure buffering.

[0029] Group 12 adapts to the extremely weak residual radiation near the inner layer: Layer 25: L-lysine is selected, with strong positive charge properties, to accurately capture the last remaining trace charged particles and gather the residual charge distribution across the entire region. Layer 26: Hyoscyamine is selected, which, after formation, can smooth out low-energy field fluctuations, converge the terminal radiation energy level, and weaken the remaining penetration potential energy. Reasoning: Approaching the bottom-line protection zone, it is necessary to gather all trace charged particles, relying on stable alkaloids to smooth the residual field and ensure a stable terminal environment.

[0030] Part Three: Innermost Self-Healing Pipeline (Layer 27): Layer 27: Arginine is selected. Main function: As the innermost and final closed-loop protective structure of the full armor, it locks in all ultra-low energy secondary particles and weak residual radiation; it undertakes long-term dynamic molecular self-repair work in space, and at the same time has excellent biocompatibility characteristics, which can be adapted to the spacecraft cabin contact interface and the personal protective interface, completely preventing residual radiation from penetrating inward.

[0031] The overall layout and deduction logic strictly follows the objective law of the gradient order of the energy spectrum of incident particles in the universe, with the outer layer responsible for ultra-high energy interception, the middle layer continuously consuming the energy of medium and low-energy particles, and the inner layer uniformly covering the residual energy, with no energy level misalignment or functional redundancy; the entire process is based on multi-dimensional quantitative ranking according to the intrinsic charge of molecules, the damping effect of functional groups, conjugate energy absorption levels, neutron moderation coefficients, and free radical quenching thresholds, and is not a subjective or arbitrary design; it clearly distinguishes between the preparation acid-base conditions and the space service environment, with logical consistency and no ambiguity; the functional division is clear and explicit, L-amino acids One component is responsible for capturing charged particles, slowing down kinetic energy, sealing gaps, and stabilizing interface voltage. The other component, alkaloids, is responsible for scattering rays, quenching free radicals, and neutralizing residual energy. These two functions are complementary and do not overlap. The alternating odd and even arrangement forms an alternating gradient electric field maze, forcibly extending the particle dissipation path and maximizing the full-spectrum protection efficiency. Combining the inherent physicochemical properties of the two types of molecules' acid-base compatibility, a time-switching pH weaving process is adopted to ensure the stability of each layer of the two-dimensional mesh from the source of preparation. After the finished product is cured, it is removed from the liquid phase and can stably adapt to various extreme service conditions in deep space.

[0032] 5. Full-process quantitative preparation process: S1 High-purity raw material directional preparation: Start the first-generation separation equipment to complete the two-stage separation of 38 amino acids (including L-type amino acids) in a weakly acidic environment of pH 5.0 to 6.0, and screen and collect all functional L-amino acids required for the 27-layer structure of this patent; Simultaneously start the second-generation alkaloid single-stage separation equipment to complete the purification and enrichment of various alkaloids in an acidic environment of pH 2.0 to 3.0, and store them in a sealed container at a constant temperature and protected from light for later use.

[0033] S2 Weaving System Environmental Pre-calibration: The sealed weaving box is equipped with constant temperature, constant humidity, electromagnetic shielding, and shock absorption modules. The zero point position of the XY coordinate microelectrode array is precisely calibrated. Two sets of liquid phase reserve systems with different standard pH values ​​are pre-configured, and all working parameters such as voltage, temperature, and amplitude are preset.

[0034] S3 Time-Sharing Dynamic pH Switching Single-Category Two-Dimensional Web Weaving Operation: Strictly following the time-sharing replacement chamber liquid phase medium according to molecular category, when weaving the L-amino acid functional web, the pH parameter range of 5.0 to 6.0 is constantly locked, and micro-electric field directional weaving is started after the environment stabilizes; after the single-layer molecular web is cured and formed, the replacement liquid phase is emptied, the chamber is cleaned, and the pH is switched to a system of 2.0 to 3.0 for alkaloid web weaving operation; the cycle is repeated to complete the preparation of all single-category independent two-dimensional biological webs step by step, and the structure is cured and locked after each layer is formed.

[0035] S4 Modular Large-Size Parallel Weaving: Large-size protective panels are divided into standardized independent sub-stations, and multiple units carry out weaving operations simultaneously to ensure seamless connection of edge molecular chains, which can stably produce square meter-level uniform functional films.

[0036] S5 27-layer gradient quantitative stacked composite: strictly following the predetermined arrangement order from the outside to the inside, the graphene protective layer, twelve sets of alternating biological functional networks, and the inner arginine bottom layer are stacked in sequence. The interlayer pressure stabilization and composite control are carried out throughout the process to control the standard range of interlayer gaps and eliminate interface voids and micro-leakage channels. The layers are physically associated with each other by hydrogen bonds and van der Waals forces, without chemical cross-linking reactions.

[0037] S6 In-situ Microscopic Detection and Self-Healing Function: Through the in-situ signal acquisition and detection module, the overall molecular arrangement density and interlayer bonding integrity are scanned, and electric field is used to correct microstructural defects at specific points; at the same time, the inner arginine self-healing response mechanism is activated to complete the closed-loop protection before leaving the factory.

[0038] S7 Precision Cutting and Scenario-Specific Shaping: Based on different application scenarios such as deep space exploration, space station coating, high-altitude aviation, and special protection laboratories, precise cutting and processing using coordinate positioning yields standardized finished deep space full-spectrum anti-radiation biological composite armor. The finished product can be directly removed from the preparation liquid environment and put into use in various extreme working conditions.

[0039] 6. Beneficial Effects of this Invention: All functional components of this invention are clearly disclosed, and the twenty-seven-layer hierarchical structure can be scientifically deduced from multiple dimensions, coupled with a complete set of quantitative process parameters; it completely distinguishes between preparation conditions and service conditions, thoroughly eliminating logical loopholes in environmental adaptability. The unique time-varying pH dynamic weaving process fundamentally solves the industry's technical pain point of incompatibility between L-amino acids and alkaloid molding environments. The self-developed three-generation technology forms a complete closed-loop chain, from raw material purification, time-varying weaving, gradient stacking to detection and empowerment, all processes are autonomously controllable, with a coherent and complete technical spectrum; it conforms to the natural distribution law of interstellar L-amino acids. The twenty-seven-layer gradient structure achieves full-spectrum radiation protection without blind spots, with an outer hard barrier for interception, a middle layer for graded dissipation, and an inner layer for self-healing, comprehensively adapting to all complex radiation conditions in space. The two-dimensional warp and weft mesh molding structure has excellent toughness, is resistant to aging, extreme temperature changes, and does not delaminate or become brittle over long periods. The finished product is not dependent on the acid and alkali preparation environment and can adapt to space vacuum service standards for a long time. The modular mass production design concept allows for seamless scaling up from small-scale experimental samples to large-area, whole-sheet protective films, promising broad prospects for industrial application. The built-in molecular-level dynamic self-healing system effectively extends on-orbit service life and significantly reduces the later maintenance and replacement costs of deep-space equipment. The entire process is achieved through pure physical electric field molding, with no chemical cross-linking byproducts, resulting in strong structural stability and a low rate of long-term protective performance degradation. The interlayer bonding mechanism is fully completed, leaving no technological gaps.

The structure consists of 27 layers in total, and the overall structure shows a pattern of decreasing radiation energy levels from the outside to the inside.

Claims

1. A time-varying pH two-dimensional woven 27-layer gradient stacked deep-space full-spectrum radiation-resistant biological composite armor, characterized in that: The overall structure is a 27-layer gradient integrated structure, consisting of two graphene rigid barrier layers, twelve alternating L-amino acid-alkaloid protective layers, and a terminal arginine self-repairing bottom layer from the outside in. All functional components are clearly defined: the two graphene layers are high-density multilayer graphene and lightly oxidized graphene; the twelve alternating molecules are, in order: L-aspartic acid + berberine, L-glutamic acid + matrine, L-serine + berberine, L-threonine + corydaline, L-cysteine ​​+ chelidonine, glycine + papaverine, L-alanine + sophoridine, L-valine + strychnine, L-leucine + evodiamine, L-isoleucine + tetrandrine, and L-histidine + fritillaria. The armor consists of alkali, L-lysine, and hyoscyamine; the innermost layer is a self-healing arginine base. This armor is fabricated using a self-developed three-generation electric field technology. The first generation employs a two-stage separation technology of 38 amino acids at pH 5.0–6.0; the second generation uses a single-stage alkaloid separation technology at pH 2.0–3.0; and the third generation only reuses the XY coordinate micro-electric field two-dimensional weaving principle without nucleotide synthesis. The weaving process uses a time-sequential dynamic pH switching process. The L-amino acid two-dimensional network formation maintains pH 5.0–6.0, while the alkaloid two-dimensional network formation switches to pH 2.0–3.

0. The two types of molecules are segmented and independently formed into a network before being layered. The above acid and alkali conditions are specific to the fabrication process, and the finished product remains stable even after being removed from the liquid phase environment. The overall layout is based on quantitative deduction of the energy spectrum of cosmic particles, molecular electrical properties, and acid-base compatibility, achieving step-by-step protection against full-spectrum deep space radiation.

2. The armor according to claim 1, characterized in that: The first-generation two-stage separation technology for 38 amino acids (including L-type amino acids) uses a weakly acidic preparation environment of pH 5.0–6.0 to make the amino acids (including L-type amino acids) electron-charged and migrated directionally from right to left under a fixed electric field. Based on the differences in charge, polarity, and β-ring arc properties, the first stage coarsely separates six major categories of amino acids, and the second stage finely separates them into 38 independent components, which are then collected by point elution with a comparison solution. After molding, the molecular structure is locked in a stable state, making it suitable for the neutral service environment in space.

3. The armor according to claim 1, characterized in that: The second-generation single-stage separation technology for alkaloids of traditional Chinese medicine uses a pH 2.0–3.0 acidic preparation environment to differentially dissociate and charge the alkaloids. The single-stage electric field completes the separation, and the high-purity raw material is obtained by rinsing with a contrast solution. After film formation and solidification, it does not rely on an acidic system and its inherent radiation protection properties are permanently retained.

4. The armor according to claim 1, characterized in that: L-amino acids can only be stably electronized and woven into a regular web in a weakly acidic preparation environment of pH 5.0–6.0; alkaloids can only maintain differentiated charged and orderly web formation in an acidic preparation environment of pH 2.0–3.

0. The two cannot share a single liquid phase forming system, and the weaving process must be carried out in stages by changing the environment and adjusting the electric field parameters. The finished protective film does not depend on the acid and alkali conditions during the preparation stage and can work stably under space vacuum and extreme temperature change conditions.

5. The armor according to claim 1, characterized in that: The overall structure strictly follows the alternating arrangement of L-amino acids and alkaloids, with discontinuous stacking of similar molecules to form an alternating gradient electric field maze, which prolongs the dissipation path of high-energy particles and improves the overall full-spectrum blocking efficiency; the interlayers rely on physical association through hydrogen bonds and van der Waals weak interactions, without chemical cross-linking structures.

6. The armor according to claim 1, characterized in that: The protective energy levels decrease progressively from the outside to the inside based on Monte Carlo simulations of typical deep-space particle energy spectra (such as protons, neutrons, and gamma rays). This range represents the theoretically optimal range, and can be finely adjusted as needed in actual fabrication. The outer layer intercepts ultra-high-energy heavy ions and primordial rays, the middle layer moderates and neutralizes medium-energy, secondary neutrons, gamma rays, and free radicals, and the inner layer gathers ultra-low-energy residual particles and achieves dynamic molecular self-repair.

7. A time-varying pH micro-electric field two-dimensional weaving system for preparing the armor of claim 1, characterized in that: It includes a sealed anti-interference weaving box, a constant temperature, humidity and pressure stabilizing module, a pH dynamic and precise control unit, an XY coordinate microelectrode array, a modular synchronous weaving unit, and an in-situ signal acquisition and detection module; it can switch between two weak acid liquid phase preparation environments in time-division, realizing independent two-dimensional weaving of single-category biomolecules and large-size whole-piece molding.

8. The weaving system according to claim 7, characterized in that: The system includes quantitative calculation models for electric field strength, molecular forces, single-step displacement, and XY coordinate positioning, while also satisfying the molecular point-binding conditions to ensure the microscopic accuracy of two-dimensional web weaving and gradient stacking. The preparation parameters are specifically set for processing and do not limit the subsequent service environment of the finished product.

9. A method for preparing a time-varying pH two-dimensional woven 27-layer gradient stacked deep-space full-spectrum radiation-resistant biological composite armor, characterized in that: The process includes the following steps: S1. Using first-generation and second-generation separation technologies, prepare all the high-purity L-amino acids and alkaloid raw materials required for the 27 layers; S2. Activate the anti-interference module of the sealed weaving box, calibrate the XY coordinate microelectrode array, and store two different pH liquid phase preparation systems; S3. Dynamically switch the weaving environment in a time-sharing manner: maintain a constant pH of 5.0–6.0 when weaving the L-amino acid web, and switch the pH to 2.0–3.0 when weaving the alkaloid web, using the third-generation electric field weaving principle to create independent two-dimensional biomolecular webs, and complete the structural solidification after each layer is formed; S4. Simultaneously weave at multiple modular workstations to prepare a large-size, whole-piece functional membrane; S5. Stack and stabilize the 27 layers in a predetermined order, with the layers firmly bonded by weak molecular interactions; S6. Perform in-situ microscopic detection and electric field defect correction to activate the end self-healing function; S7. Precisely cut according to application specifications to obtain the finished deep-space radiation-resistant biological armor, which can be put into use immediately after being removed from the preparation liquid phase environment.

10. The weaving system according to claim 7, characterized in that: The scope of protection of this application is limited to the 27-layer molecular combination structure of the armor, the time-varying pH weaving process, the three-generation technology integration application scheme, and the gradient stacking molding method. The internal chip layout of the integrated circuit and the underlying proprietary circuit design are not within the scope of protection of this patent.
