The development of safer and more sustainable polymers increasingly relies on the substitution of substances of concern. Among these, bisphenols, widely used in the polymer industry, are under scrutiny due to their endocrine-disrupting effects and are being progressively banned, particularly in food-contact applications such as coatings. Lignin, a renewable and bio-aromatic alternative, has garnered industrial interest as a potential substitute. However, variability in its quality and sourcing continues to limit its widespread adoption in material applications. In this study, a series of epoxy resin formulations were developed using glycidylated depolymerized lignin (GDL) with different characteristics, alongside increasing levels of bio-based content through the substitution of fossil-based epoxy with bio-based alternatives. The resulting crosslinked networks were thoroughly characterized, and their structure-property relationships were investigated through thermomechanical performance analysis. Here, we establish fully lignin-based epoxy systems and demonstrate their coating performance on metal substrates through standardized industrial evaluation methods. Coating effectiveness on metal substrates was evaluated based on appearance, adhesion, peel and impact resistance. Overall, this work demonstrates that lignin can play a key role in the transition to bio-based coatings. However, the success of this transition relies on both the consistency of the lignin source and the design of the formulation. These findings represent a significant step toward the development of high-performance, sustainable, versatile, bio-based but viable and scalable coating materials.

开发更安全、更可持续的聚合物越来越依赖于对相关物质的替代。其中，广泛用于聚合物工业的双酚类物质因其内分泌干扰作用而受到严格审查，并逐渐被禁止，特别是在涂料等与食品接触的应用中。木质素是一种可再生的生物芳香替代品，作为一种潜在的替代品已经引起了工业的兴趣。然而，其质量和来源的变化仍然限制了其在材料应用中的广泛采用。在本研究中，利用具有不同特性的缩水甘油酰化解聚木质素（GDL）开发了一系列环氧树脂配方，同时通过用生物基替代品替代化石基环氧树脂来提高生物基含量。对所得到的交联网络进行了全面表征，并通过热力学性能分析研究了它们的结构-性能关系。在这里，我们建立了全木质素基环氧树脂体系，并通过标准化的工业评估方法展示了它们在金属基材上的涂层性能。从外观、附着力、剥离性和抗冲击性等方面评价了涂层在金属基体上的有效性。总的来说，这项工作表明木质素可以在向生物基涂料的过渡中发挥关键作用。然而，这种转变的成功依赖于木质素来源的一致性和配方的设计。这些发现代表着向高性能、可持续、多用途、生物基、可行和可扩展的涂层材料的发展迈出了重要的一步。

Silver-plated polymer microspheres are pivotal for developing cost-effective conductive adhesives, yet achieving high-quality, non-agglomerated plated layers without costly catalysts remains challenging. This study presents a novel electroless plating strategy to fabricate silver-plated polystyrene (Ag@PS) microspheres (particle size range: 1–6 μm), where pre-formed silver nuclei act as seeds for shell growth, eliminating the need for external catalysts. Under optimized conditions involving temperature, concentration, and dispersant control, the resulting Ag@PS microspheres exhibited excellent monodispersity, a uniform silver layer, and a high silver content of 71.4 wt%. When applied as conductive fillers in epoxy adhesive, the Ag@PS-based adhesives achieved a percolation threshold of 55 wt%, significantly lower than that of solid silver-filled adhesive (65 wt%), and reached a volume resistivity of 8.8 × 10⁻⁴ Ω·cm with 10 % less filler. This work provides a scalable, cost-saving strategy to produce high-performance conductive adhesives for modern electronics.

Polymers used in protective coatings often suffer stress-induced degradation under dynamic loading, especially in deep-sea environments dominated by high hydrostatic pressure and fluid shear. Here, we report a stress-transforming polymer that actively converts mechanical energy into network adaptation rather than passively withstanding it. This material combines a robust epoxy backbone with a dynamic network of side-chain-anchored diselenide mechanophores and a complementary hydrogen-bonding network. The diselenide motifs, grafted via hexamethylene diisocyanate, act as force-activated sacrificial linkages that undergo homolytic scission and radical exchange under stress, enabling topological remodeling of the network. Spectroscopic analyses (FT-IR, ¹H NMR, XPS) confirmed the successful synthesis. Upon mechanical activation (3 MPa pre-compression, 5 min), the polymer exhibits remarkable autonomous self-strengthening, with tensile strength and toughness increased by approximately 308% and 194%, respectively. Cyclic tensile and DMA analyses revealed stress-induced reinforcement and pronounced energy dissipation. Electron paramagnetic resonance spectroscopy directly detected selenium-centered radicals post-compression, while in situ FT-IR captured reversible bonding events, providing combined evidence for the force-triggered SeSe recombination and sacrificial hydrogen bonding. In simulated deep-sea conditions (6 MPa + 3 m/s, 3.5 wt% NaCl), the optimal coating formulation (STP₅–EP) demonstrated superior anti-corrosion performance, maintaining exceptional barrier integrity with high charge-transfer resistance (2.3 × 10¹⁰ Ω·cm²) and a crack-free morphology after 240 h. This work establishes a viable molecular engineering paradigm for developing coatings that actively resist mechanical degradation through intrinsic stress transformation, offering a pathway to enhanced durability in extreme environments.

用于保护涂层的聚合物在动态载荷下往往会发生应力引起的降解，特别是在高静水压力和流体剪切主导的深海环境中。在这里，我们报道了一种应力转化聚合物，它主动地将机械能转化为网络适应，而不是被动地承受它。这种材料结合了坚固的环氧树脂骨架、侧链锚定的二硒化机械基团的动态网络和互补的氢键网络。二烯基序通过六亚甲基二异氰酸酯接枝，作为力激活的牺牲键，在压力下进行均溶断裂和自由基交换，从而实现网络的拓扑重塑。光谱分析（FT-IR, 1H NMR， XPS）证实了合成的成功。经机械活化（预压缩3 MPa， 5 min）后，聚合物表现出显著的自增强特性，拉伸强度和韧性分别提高了约308%和194%。循环拉伸和DMA分析显示应力诱导的钢筋和明显的能量耗散。电子顺磁共振光谱直接检测压缩后的硒中心自由基，而原位FT-IR捕获可逆键事件，为力触发的SeSe重组和牺牲氢键提供了综合证据。在模拟深海条件下（6 MPa + 3 m/s, 3.5 wt% NaCl），最佳涂层配方（STP5-EP）表现出卓越的抗腐蚀性能，在240 h后保持优异的屏障完整性，具有高电荷转移阻力（2.3 × 1010 Ω·cm2）和无裂纹形貌。该工作为开发通过内在应力转变积极抵抗机械降解的涂层建立了可行的分子工程范式。提供了在极端环境下增强耐用性的途径。

Ice accumulation severely threatens the safe operation of critical systems, and passive icephobic surfaces have attracted significant attention as an effective strategy. Conventionally, slippery liquid-infused porous surfaces (SLIPS) achieve ultralow ice adhesion, but the durability is undermined by lubricant depletion under complex environmental conditions. In this study, we propose a phase-change-driven solid-state lubricating icephobic surfaces (PLIPS), which achieves nearly zero ice adhesion through interfacial physical isolation, and the performance can be fully regenerated through lubricant replenishment and in-situ absorption. The coating consists of a gel network formed by blending epoxy resin, polydimethylsiloxane, and alkanes, where the alkanes crystallize and migrate toward the surface driven by low temperature, forming a porous solid lubricating layer at the ice-coating interface, which serves as a thermal barrier and physically separates the ice from the substrate. Through systematic investigation of lubricant migration, phase transition, and replenishment behavior, the PLIPS achieved nearly zero ice adhesion strength and a 137% longer droplet freezing delay (1018 s at −20 °C) compared with the PDMS-only control. After 30 icing–deicing cycles, ice adhesion remained extremely low (< 35 kPa), and the initial performance could be fully restored through simple thermal immersion for lubricant replenishment. This work provides a novel strategy for durable and replenishable anti-icing coatings.

积冰严重威胁着关键系统的安全运行，被动疏冰表面作为一种有效的策略受到了广泛的关注。通常，光滑的液体注入多孔表面（slip）可以实现超低的冰附着，但在复杂的环境条件下，润滑剂耗尽会影响其耐久性。在本研究中，我们提出了一种相变驱动的固态润滑憎冰表面（PLIPS），该表面通过界面物理隔离实现了近乎零的冰粘附，并且通过补充润滑剂和原位吸收可以完全再生其性能。涂层由环氧树脂、聚二甲基硅氧烷和烷烃混合形成的凝胶网络组成，其中烷烃在低温的驱动下结晶并向表面迁移，在冰涂层界面处形成多孔固体润滑层，起到热障作用并将冰与基体物理分离。通过对润滑油迁移、相变和补充行为的系统研究，与仅使用pdms的对照组相比，PLIPS的冰粘附强度几乎为零，液滴冻结延迟（- 20°C时为1018 s）延长了137%。在30次冰除冰循环后，冰的粘附力保持在极低的水平（< 35 kPa），通过简单的热浸补充润滑剂可以完全恢复初始性能。这项工作为研制耐用、可补充的防冰涂料提供了一种新的策略。

A hydrophobic polymer coating with antibacterial and antifouling properties was developed by employing a biomimetic strategy using N-vanillylnonanamide, a capsaicin analog derived from chili pepper. Poly(4-chloromethylstyrene) was first synthesized by free-radical polymerization and was subsequently functionalized via nucleophilic substitution with N-vanillylnonanamide (PEP) to covalently introduce capsaicin-based side chains. A series of polymers (PPEP#, # = 20, 40, 60, 80, and 100) was obtained, and their structural, thermal, and mechanical properties were studied. The thin films were fabricated on glass and cellulose substrates by spin- and dip-coating exhibited high optical transparency. As an environmentally friendly alternative to toxic fluorinated compounds, these coatings incorporate bio-inspired molecular structures with functional surface properties. Surface energy measurements and angle-resolved X-ray photoelectron spectroscopy confirmed a progressive increase in surface hydrophobicity with increasing PEP content. The coatings also sealed the porous structure of the cellulose, significantly reducing its water permeability, while maintaining sufficient mechanical integrity and adhesion to the substrate. Antibacterial adhesion tests demonstrated that PPEP100 inhibited Escherichia coli attachment by 100% and Staphylococcus aureus attachment by 92.3%. Long-term adhesion tests under biofilm-promoting conditions further showed that PPEP100 maintained antibacterial adhesion resistance over 7 days. Antifouling assessments using dyes and household contaminants indicated improved performance with increasing PEP substitution, attributed to reduced surface energy and suppressed adsorption. Furthermore, PPEP100 exhibited excellent structural stability under various extreme conditions. These findings highlight PPEP# as a promising eco-friendly coating, which incorporates hydrophobicity with durable antibacterial and antifouling properties without relying on fluorinated materials.

采用从辣椒中提取的辣椒素类似物n -香兰素壬胺的仿生策略，制备了一种具有抗菌和防污性能的疏水聚合物涂层。聚（4-氯甲基苯乙烯）首先通过自由基聚合合成，然后通过n-香草壬胺（PEP）亲核取代引入共价辣椒素侧链进行功能化。得到了一系列聚合物（PPEP#、# = 20、40、60、80和100），并对其结构、热性能和力学性能进行了研究。采用自旋镀膜和浸渍镀膜的方法在玻璃和纤维素基底上制备了具有高光学透明度的薄膜。作为有毒氟化化合物的环保替代品，这些涂料结合了具有功能性表面特性的生物启发分子结构。表面能测量和角度分辨x射线光电子能谱证实，随着PEP含量的增加，表面疏水性逐渐增加。涂层还密封了纤维素的多孔结构，显著降低了其透水性，同时保持了足够的机械完整性和对基材的附着力。抗菌粘附试验表明，PPEP100对大肠杆菌的粘附抑制率为100%，对金黄色葡萄球菌的粘附抑制率为92.3%。在生物膜促进条件下的长期粘附试验进一步表明，PPEP100在7 d内保持抗菌粘附抗性。使用染料和家庭污染物进行的防污评估表明，随着PEP取代量的增加，由于表面能的降低和吸附的抑制，性能得到了改善。此外，PPEP100在各种极端条件下都表现出优异的结构稳定性。这些发现突出了PPEP#作为一种很有前途的环保涂料，它结合了疏水性、持久的抗菌和防污性能，而不依赖于氟化材料。

The escalating global energy crisis and electromagnetic pollution pose dual threats to sustainability and human health. Developing multifunctional materials for zero-energy cooling and effective EMI shielding is therefore crucial. Herein, based on high-speed shear and ultrasonic dispersion, a stretchable Janus coating film was fabricated via a scalable method combining solvent evaporation and humidity-assisted phase separation. The film integrates passive radiative cooling, electromagnetic interference shielding, Joule heating, self-cleaning, and flame retardancy in a single system. The radiative cooling layer, comprising a thermoplastic polyurethane matrix with BaSO₄ micro-nanoparticles and SiO₂-HA fillers, forms a multiscale porous structure that leverages Mie scattering, multiple reflection, and phonon-polariton resonance to achieve high solar reflectance (90.46%) and emissivity (95.71%). It also exhibits superhydrophobicity (CA > 150°) and low thermal conductivity. The EMI layer, constructed with a graphene-based dense-porous gradient, resolves the recalcitrant problem of combining high shielding efficiency and excellent mechanical properties with graphene as filler material. It employs an absorption-reflection-absorption mechanism that yields an average shielding effectiveness of 36.07 dB (X-band) and fast electrothermal heating to 93.3 °C at 7 V. A halogen-free phosphorus additive provides self-extinguishing flame retardancy, and the film maintains excellent flexibility (strain 243%). Outdoor tests show an average daytime sub-ambient cooling of 5.5 °C and a theoretical cooling power of 84.27 W/m².

Epoxy resin (EP) coating is widely used in the construction field due to its excellent performance. Microcapsules are prepared by self-assembly of TiO₂ on the surface of azodicarbonamide (ADC) to enhance the flame-retardancy and smoke suppression of epoxy resin, and to address the ultraviolet failure of azodicarbonamide in practical applications. By adding 5 wt% of azodicarbonamide microcapsules to the epoxy resin, the limiting oxygen index (LOI) of the composite EP was increased from 20 % to 31 % compared with the pure EP, reaching the level of flame-retardant material. Through cone calorimeter test (CCT), the total heat release (THR), peak heat release rate (pHRR) and total smoke production (TSP) of composite EP were reduced by 62.09 %, 54.88 % and 46.98 %, respectively, and the epoxy resin was equipped with a very good charring effect, which improved the flame retardancy. In addition, SEM images showed that the ADC was successfully coated by TiO₂, which avoided the ADC from being exposed to UV leading to failure and enhanced its effectiveness in practical applications.

Traditional cotton fabric flame retardants containing phosphorus frequently suffer from formaldehyde emissions, excessive smoke release, and insufficient washing durability. This research developed TBMP, an innovative flame retardant coating absent halogens and formaldehyde which was developed based on an integrated P/N/B synergistic design. Cyanuric chloride served as a nitrogen rich backbone, phosphoric acid as an acid source, boric acid as an efficient smoke suppression component, and biomass derived mannitol as a sustainable carbon source, reflecting green and environmentally sustainable development principles. At a weight gain of 24.0%, the treated fabric achieved a LOI of 46.9% and a short char length of 6.3 cm. Thermogravimetric analysis showed enhanced char formation, with char residues increased by 10.88% in air and 28.09% in nitrogen at 700 °C. Cone calorimetry outcomes indicated a peak heat release rate decrease of 88.73% and a total heat release reduction of 47.07%, while maintaining a competitively low total smoke release (TSR) of 0.47 m² among superior flame-resistant systems, thus achieving a synergy of high flame retardancy and controlled smoke release. Furthermore, the formation of stable P–O–C covalent bonds between TBMP and cellulose endowed the treated fabric with excellent washing durability, retaining effective flame retardant performance after 50 laundering cycles. Meanwhile, the coating exerted only a minor influence on the whiteness and physical properties of the fabric. This work provides a sustainable and efficient strategy for constructing multifunctional flame retardant systems for cotton textiles.

传统的含磷棉织物阻燃剂经常存在甲醛释放、烟雾释放过多、洗涤耐久性不足等问题。基于P/N/B一体化协同设计，研制了新型无卤无甲醛阻燃涂料TBMP。三聚氰尿酸作为富氮骨架，磷酸作为酸源，硼酸作为高效抑烟组分，生物质衍生甘露醇作为可持续碳源，体现了绿色环保的可持续发展原则。在增重24.0%的情况下，织物的LOI为46.9%，焦炭长度为6.3 cm。热重分析表明，在700℃时，空气和氮气中炭的残留量分别增加了10.88%和28.09%。锥量热法结果表明，峰值放热率降低了88.73%，总放热率降低了47.07%，同时总放烟量（TSR）保持在0.47 m2的较低水平，在优异的阻燃体系中实现了高阻燃性和控烟的协同作用。此外，在TBMP和纤维素之间形成稳定的P-O-C共价键，使处理后的织物具有优异的洗涤耐久性，在洗涤50次后仍保持有效的阻燃性能。同时，涂层对织物的白度和物理性能的影响很小。本研究为构建多功能棉织物阻燃体系提供了一种可持续、高效的策略。

The failure of superhydrophobic materials in low-surface-tension liquid environments remains a critical challenge. In this paper, we fabricate a superamphiphobic coating through a facile spray-coating technique based on PVDF and fluorinated SiO₂ (F-SiO₂) nanoparticles. The coating exhibits contact angle (CA) greater than 150° and sliding angle (SA) below 5° for water, ethylene glycol, peanut oil, and hexadecane, demonstrating excellent repellency toward liquids with a wide range of surface tensions. Furthermore, the coating displays remarkable anti-fouling and self-cleaning properties, as liquids of various surface tensions can effectively remove solid contaminants from the surface. Electrochemical impedance spectroscopy (EIS) and neutral salt spray tests confirm its superior anti-corrosion function. After 960 h of salt spray exposure, the surface retains its superhydrophobicity, although its superoleophobicity shows a slight decline. Investigations of icing behavior reveal that the superamphiphobic coating significantly delays water droplet freezing, which is primarily attributed to its effective suppression of nucleation and heat transfer rates. We believe the development of this multifunctional coating, integrating superhydrophobicity, superoleophobicity, self-cleaning, anti-fouling, anti-corrosion, and anti-icing properties, holds substantial application potential and broad prospects across numerous industrial fields.

超疏水材料在低表面张力液体环境中的失效仍然是一个关键的挑战。本文以PVDF和氟化SiO2 （F-SiO2）纳米颗粒为基材，采用快速喷涂技术制备了超双疏涂层。该涂层对水、乙二醇、花生油和十六烷的接触角（CA）大于150°，滑动角（SA）小于5°，对具有大范围表面张力的液体表现出优异的拒水性。此外，由于不同表面张力的液体可以有效地去除表面的固体污染物，该涂层具有显著的防污和自清洁性能。电化学阻抗谱（EIS）和中性盐雾试验证实了其优异的防腐性能。盐雾作用960 h后，表面的超疏水性保持不变，但其超疏油性略有下降。对结冰行为的研究表明，超双疏涂层显著延缓了水滴的冻结，这主要归因于其有效抑制了成核速率和传热速率。我们相信，这种集超疏水、超疏油、自洁、防污、防腐、防冰等性能于一体的多功能涂料的开发，在众多工业领域具有巨大的应用潜力和广阔的前景。
