［Objective］Silicon（Si）is regarded as one of the most promising anode materials forlithium-ion batteries due to its ultrahigh theoretical specific capacity. However，its huge volume expansion（>300%）leads to repeated rupture and regeneration of the solid-electrolyte interphase（SEI） film，resulting in electrode pulverization and rapid capacity fading. To address this issue，a multifunctional aqueous binder that can accommodate volume changes，maintain electrode structural integrity，and ensure efficient lithium-ion transport was designed and prepared.［Methods］First，a dynamic network（PAA-FeCA） was constructed via the coordination interaction between Fe³⁺ from partially dissociated ferric citrate（FeCA） and carboxyl groups in polyacrylic acid（PAA）. Subsequently，polypyrrole（PPy）was introduced to penetrate the matrix to form a continuous three-dimensional conductive network，which interlocks with the PAA-FeCA dynamic coordination network， establishing a dual-crosslinked system with synergistic rigidity and flexibility.［Results］The silicon anode based on this binder exhibited excellent comprehensive performance. The PAA-FeCA-PPy@Si electrodeshowed significantly improved flexibility and adhesion. At a rate of 0. 2 C（1 C=4 200. 00 mAh/g）and 0. 5 C，it delivered high reversible discharge capacities of 4 089. 39 mAh/g and 3 451. 90 mAh/g， respectively.［Conclusion］ The synergistic design of dynamic coordination bonds and conductivenetworks is an effective strategy to solve the core failure problems of silicon anodes，providing a new approach for the development of high-performance silicon-based anodes.

［Objective］Leveraging the favorable structural properties of hyperbranched polymersand polycarbonate diols to expand the application scenarios of waterborne polyurethane coatings.［Methods］ Using poly（propylene carbonate） diol（PPCD）， isophorone diisocyanate（IPDI）， 2，2-dimethylolpropionic acid（DMPA）， etc. as raw materials，a series of UV-curable waterborne hyperbranched polyurethane acrylate dispersions（WHPUA） were prepared by adjusting the DMPA content. The chemical structures of WHPUA were characterized by Fourier transform infrared spectroscopy and nuclear magnetic resonance spectroscopy. The effects of the R value and DMPA content on the properties of WHPUA were investigated.［Results］ As the R value increased，the particle size of the dispersions gradually decreased，the coating hardness improved，and the adhesion increased and then decreased. When the R value was 1. 6，the coating exhibited high hardness， relatively stable dispersion performance，and strong interfacial adhesion with PET substrate. With an increase in DMPA content，the particle size of the dispersions gradually decreased. When the DMPA content was 19. 4 mmol，the prepared WHPUA-4 dispersion showed favorable overall performance， with a coating hardness of 3H，an adhesion rating of 0，a water contact angle of 64. 3° for the film，as well as good mechanical properties and thermal stability.［Conclusion］The unique three-dimensionalspherical structure of hyperbranched polymers enhances the physicochemical properties of linearpolyurethane acrylate water-based coatings，broadening their application scenarios. 

［Objective］By comparing the dispersion effects of different wetting and dispersing additives on carbon black，the effects of deflocculating property of the additives on the jetness of paintfilms and color stability of tinting paints were investigated.［Methods］Waterborne resin-freecarbon black pigment concentrates with different additives were prepared，and applied for full-shade blackrefinish coatings and tinting industrial coatings. The jetness of the refinish coatings was measured bothbefore and after clear topcoat application. For tinted paints，the storage stability（50 ℃/7 d）of dry film color was assessed，and the particle size of pigment concentrates was measured.［Results］For high color carbon black pigments，the resulting black basecoat films with higher jetness and bluer undertonecould be achieved using D2014. When D2014 was used to prepare a pigment concentrate of a mediumcolor carbon black，the tinted coatings deliver superior color stability of the paint film. The particle sizemeasurement results verified that D2014 could stabilize medium color carbon black in a finelydispersed state.［Conclusion］ High jetness of the coating film was a reflection of thorough deflocculation of carbon black pigment. Meanwhile，dispersants with strong deflocculating performance coud also improve the color stability of films of the tinted coatings.

［Objective/Significance］ Waterborne polyurethane（WPU） is an important matrix resin for environmentally friendly coatings；however，the hydrophilic groups in its molecular chains leadto poor water resistance and weak barrier properties，which severely limit its application in anti-corrosion coatings.［Analysis/Discussion/Progress］Focusing on the enhancement of WPU coatings anti-corrosion performance，this paper systematically reviews the research progress in high-performance WPU coatings-shifting from passive to active protection. The paper focuses on the mechanisms by which strategies such as crosslinked network construction，organic-inorganic hybridization，two-dimensional nanofiller incorporation，superhydrophobic interface construction，and multicomponent synergistic modification enhance the densification and barrier properties of coatings. It also summarizes active protection methods，including self-healing of damage，smart corrosion inhibition with controlled release，and visual corrosion early warning.［Conclusion/Prospect］ Finally，future development directions in this field are envisioned from the aspects of functional monomer moleculardesign，precise regulation of WPU structure，and systematic optimization of coating formulation and preparation processes.

［Objective］ In order to overcome the shortcomings of traditional experiments intracking free radical evolution and revealing the microscopic reaction pathways of coatings，the Reactive force field molecular dynamics（ReaxFF MD）simulations were uesed to investigate the flame-retardant mechanism of lignin/ammonium polyphosphate composite coating at the molecular level.［Methods］Three crosslinked coating models，namely epoxy resin（EP），epoxy resin-lignin（EP-Lig）， and epoxy resin-lignin-ammonium polyphosphate（EP-Lig-APP），were constructed. The ReaxFF MD simulations were employed to systematically simulate the pyrolysis products and their evolution patterns.［Results］ The results showed that EP pyrolysis released reactive free radicals such as ·H，·OH，·CH，C₂，and ·CHO. Lignin，introduced an aromatic carbon framework through dehydrogenation，reduced the H/C ratio of the system，and provided a carbon source for the continuous carbon layer. Ammonium polyphosphate captured ·H/·OH and released non-flammable gases including NH₃，N₂ and H₂O，achieving gas-phase dilution，inhibiting EP decomposition and promotingcarbon layer expansion. Meanwhile，·PO radicals and the carbon framework formed C—O—P crosslinks，generating larger carbon clusters，blocking the transfer of heat and flammable volatiles and enhancing the flame-retardant properties of the coating.［Conclusion］ ReaxFF MD simulation elucidated the intumescent flame-retardant mechanism of the epoxy coating enhanced synergistic ligninand ammonium polyphosphate at the microscopic scale，providing a theoretical basis for the design of bio-based intumescent flame-retardant coatings.

［Objective/Significance］In certain extreme environments，the hydrophilic surface of carbon fiber/epoxy resin（CF/EP）composites is prone to icing，which can lead to safety hazards and economic losses. Consequently，developing efficient，low-energy anti-icing/de-icing technologies has become a research hotspot in this field.［Analysis/Discussion/Progress］ This paper systematicallyreviews anti-icing technologies based on constructing superhydrophobic surfaces and electrothermalde-icing technologies for CF/EP composites. Superhydrophobic surfaces can be constructed on CF/EPcomposites through coating methods，hard template pressing，physical processing and etching. Thesemethods reduce the contact area between water droplets and the surface，decrease interfacial heat transfer，delay ice nucleation，and significantly diminish the mechanical interlocking between ice and the substrate. Consequently，ice adhesion is greatly reduced，enabling easy ice shedding. Additionally，by constructing conductive coatings/plating on the surface of CF/EP composites or introducingconductive networks into the substrate，CF/EP composites can be endowed with the ability to generateJoule heating for electrothermal de-icing.［Conclusion/Prospect］Future research should be focused on the development of structure-function integrated intelligent systems，the establishment of environmental adaptability evaluation systems，and the cross-integration of emerging technologies（such as phase change materials and self-healing materials），so as to promote the anti-icing/de-icingtechnology of CF/EP composites towards engineering applications.

［Objective］ To address the environmental and process bottlenecks faced in thepreparation of current superhydrophobic coatings，there is an urgent need to develop alternativetechnologies based on biomass raw materials that are low in complexity and eco-friendly.［Methods］ In this study，expired milk was used as the raw material，and natural pigments of different hues wereintroduced as colorants. Complex protein denaturation was achieved through alkali induction usingsodium hydroxide，and linoleic acid was added to promote a thiol-ene click reaction between long alkylchains and thiol groups，thus multifunctional fluorine-free superhydrophobic biomass coatings were prepared.［Results］The results indicate that the treated fabric coatings exhibited a maximum water contact angle（WCA）of 154. 7° and a rolling angle（WSA）of 8°；the ultraviolet protection factor（UPF） was increased significantly from 37. 2 to 4 770. 8，and the transmittance of long-wave ultraviolet（UVA）was decreased from 5. 105% to 0. 030%. Under a low-temperature environment of -15 ℃， 10 μL droplet on the coating surface can be delayed from freezing for up to 1 906 s. The coatings stillmaintained dynamic superhydrophobic properties even after high-temperature cycling at 120 ℃，low-temperature refrigeration cycling at -15 ℃，and exposure to different chemical environments， demonstrating its adaptability to complex and variable practical applications.［Conclusion］This study not only breaks through the environmental protection and process bottlenecks of traditional superhydrophobic coatings，but also creats a new type of green composite coating that combines eco-friendliness，functionalization and aesthetic value，providing an innovative path for the high-value utilization of waste resources. 

［Objective］ To address the issues of insufficient heat resistance，poor interfacial compatibility，and inadequate water resistance of conventional optical fiber coatings under high-temperature and high-humidity environments，and to enhance their long-term reliability under harsh conditions，［Methods］a hybrid prepolymer containing POSS/hydroxyl/epoxy groups（POSS-FG-OH） was first synthesized via free radical copolymerization of octavinyl polyhedral oligomeric silsesquioxane（OV-POSS）， tridecafluorooctyl acrylate（G06c）， glycidyl methacrylate（GMA）， and hydroxypropyl acrylate（HPA）. Subsequently，long-chain fluorinated POSS-polyurethane（F-POSS-PU） was prepared by sequential polymerization of POSS-FG-OH with polytetrahydrofuran diol（PTMG2000） and isophorone diisocyanate（IPDI）. Finally，photocurable double bonds were introduced throughmethacrylic acid esterification to obtain the UV-curable fluorinated POSS-polyurethane（UV-F-POSS-PU）optical fiber coating. The structure and properties of the products were characterized by FT-IR， GPC，TGA，and TMA，and the effects of POSS content on the thermal stability，water resistance，mechanical properties，photocuring behavior，and optical transmission loss of the coated fibers were systematically investigated.［Results］ The coating with 45%POSS effectively prevents the agglomeration of inorganic nanoparticles and significantly enhances the thermal stability，dimensional stability，water resistance，and interfacial adhesion of the coating，leading to a substantial improvement in the signal transmission reliability of optical fibers in high-temperature and high-humidity environments.［Conclusion］The developed material demonstrates significant application prospects inspecialty optical fibers for extreme environments such as aerospace and geological exploration.

［Objective］ This study utilizes structural synergistic effect to design an organic-inorganic hybrid coating system，investigating the effects of modified SiO₂ dosage on the hydrophobicity and wear resistance of the composite coating featuring high adhesion，high roughness，and low surface energy.［Methods］Using perfluorooctyltrichlorosilane（FOTS）， tetraethyl orthosilicate（TEOS）and 3-glycidyl oxypropyltrimethoxysilane（KH-560）as raw materials，an integrated organic-inorganic hybridcoating system was constructed through structural synergistic design. Modified SiO₂ particles with KH-560 were added to enhance the dispersion of nanoparticles in the coating. The wear-resistant superhydrophobic coating was prepared via spray deposition. Performance characterization was conducted using infrared spectroscopy，scanning electron microscopy，contact angle measurements and wear resistance tests.［Results］ When 100 mg of modified SiO₂ was added，the composite coating achieved a water contact angle of 151. 0°，meeting superhydrophobic standards. After 40 friction cycles， the contact angle remained at 117. 7°，demonstrating excellent wear resistance and hydrophobic performance.［Conclusion］The co-hydrolysis of FOTS and TEOS can reduce the surface energy of the coating，build rough micro-nano structures，and enhance hydrophobicity. The addition of couplingagent KH-560 and KH-560-modified nano-SiO₂ can improve the interfacial bonding between organicand inorganic phases. It further increases the surface roughness，and enhances the adhesion between coating and substrate，as well as hydrophobicity and wear resistance. 

［Objective］To develop a multifunctional photocurable coating with integrated flame-retardant and antimicrobial properties.［Methods］Phytic acid was modified with 2-（dimethylamino） ethyl methacrylate（DEM） at varying dosage ratios and UV-cured into coatings. Material characterization employed FT-IR， 1H NMR，and XPS. The photopolymerization behavior，basic properties，thermal stability，flame retardancy，flame retardant mechanism，and antibacterial performance of the coatings were systematically investigated.［Results］ With the DEM dosage increased，the conversion rate of carbon carbon double bonds in the coating decreased，hardness increased，flexibility decreased，thermal stability increased，ultimate oxygen index decreased，and antibacterial performance was not significantly affected. The prepared coating mainly promoted carbon formation through phytic acid to achieve UL94V-0 level flame retardancy，while achieving 100% antibacterial activity against both E. coli and S. aureus.［Conclusion］Photocurable phytic acid-based coatings integrate outstanding flame-retardant and antimicrobial properties，offering an effective approach for the fabrication of multifunctional bio-based UV-curable protective coatings.

［Objective］ To improve the service durability of the protective coating systems for concrete structures，a polydopamine（PDA）-based nano-bionic composite coating system was designed and evaluated.［Methods］ Two nano-bionic modified particles，denoted Pal@PDA（1∶ 4） and Pal@PDA（1∶1），were prepared by coating dopamine hydrochloride onto palygorskite（Pal）powder at different mass ratios. These particles were then incorporated into epoxy varnish and polyurethane varnish to formulate a nano-bionic epoxy sealing primer and a nano-bionic high-performance polyurethane topcoat，respectively. The effect of Pal@PDA（1∶1）on the mechanical properties and corrosion resistance of the polyurethane topcoat was examined. In addition，the chloride penetration resistance，artificial weathering resistance，and adhesion of the nanocomposite system were comparedwith those of a conventional epoxy primer plus polyurethane topcoat system.［Results］ The results show that incorporating Pal@PDA（1∶1） into the polyurethane varnish effectively enhanced the flexibility，adhesion，and alkali resistance of the coating film. At a Pal@PDA（1∶1）loading of 5%，the tensile strength and elongation at break increased by 24. 3% and 40. 3%，respectively，relative to pure polyurethane. For the nanocomposite system，in which both the primer and topcoat contained 5%Pal@PDA，the non-steady-state chloride migration coefficient decreased by 36. 6% and the glossretention after artificial weathering was increased by 12. 5% compared with the control system.Furthermore，the bond strength after 1 a of water immersion increased by 1. 5 times，reaching 4. 20 MPa.［Conclusion］ These findings demonstrate that the PDA-based nano-bionic compositeprotective coating system exhibits markedly superior service durability，providing an effective strategy for the long-term protection of concrete structures.

［Objective/Significance］ Basalt materials are low-cost，chemical stable，and abundantly available，exhibit significant potential for application in anti-corrosion coatings. Reviewingtheir research progress can provide a reference for developing low-cost，high-performance anti-corrosion coating.［Analysis/Discussion/Progress］ The mechanisms and research status of basalt-based anti-corrosion coating were summarized from three technical routes：fiber reinforcement，flake barrier effects，and two-dimensional nanosheet fabrication. Four strategies for interfacial modificationof basalt fibers were emphasized，including acid/alkali etching，silane coupling agent modification， plasma activation，and nanoparticle decoration. The inherent contradiction between aspect ratio anddispersibility in the labyrinth effect of basalt flakes was elucidated，and the advantages of ultrathin nanosheets in achieving dense barrier performance were discussed. Common challenges were identified， such as insufficient interfacial compatibility，dispersion difficulties at high filler contents，limited degree of functionalization，and a lack of long-term service evaluation data. Furthermore，bottlenecks including the absence of systematic cross-comparisons among different modification strategies wereanalyzed.［Conclusion/Prospect］ Future efforts should focus on the controllable preparation andstructure-property relationship basalt nanosheets，functional design based on the intrinsic composition of basalt，and multi-environment coupled service evaluation，thereby advancing basalt-based anti-corrosion coating toward active protection，self-healing，and intelligent multi-functionality.
