Persistent biofilms on medical device surfaces account for up to 80 % of chronic clinical infections, posing a major challenge to infection control and patient safety. To overcome this limitation, a zwitterionic polymer–PEGDGE-TAU-CCDP (PTC), was synthesized using polyethylene glycol diglycidyl ether (PEGDGE), taurine (TAU), and 2-chloro-3′,4′-dihydroxyacetophenone (CCDP). The incorporation of catechol functionalities enabled the polymer with redox activity under aerobic and ion-rich environments, a property previously associated with antibacterial behavior in catechol-based systems. Ultraviolet–visible (UV–Vis), Fourier-transform infrared (FTIR), and proton nuclear magnetic resonance (¹H NMR) spectroscopy confirmed the successful synthesis and catechol incorporation. Quantitative analysis revealed a CCDP grafting efficiency of approximately 29 %. Notably, the addition of ε-Polylysine (EPL) enhanced coating adhesion to various substrates without compromising the intrinsic antibacterial activity of the material. Bacterial growth curves, minimum inhibitory concentration (MIC), and minimum bactericidal concentration (MBC) assays demonstrated that EPL/PTC had an MIC of 0.31 mg/mL and an MBC of 1.25 mg/mL. Furthermore, the EPL/PTC-coated silicone rubber exhibited approximately 85 % biofilm inhibition and 76 % antifouling efficiency. By combining antifouling and antibacterial properties within a single system, this strategy achieves multifunctional performance that is rarely observed in conventional surface treatments. These findings highlight EPL/PTC as a promising candidate for reducing surface fouling and infection risks, thereby supporting its potential application in developing safer biomedical device materials.

医疗器械表面的持久性生物膜占慢性临床感染的80%，对感染控制和患者安全构成重大挑战。为了克服这一限制，以聚乙二醇二甘油酯醚（PEGDGE）、牛磺酸（TAU）和2-氯-3′，4′-二羟基苯乙酮（CCDP）为原料合成了两性离子聚合物peg -TAU-CCDP （PTC）。儿茶酚功能的结合使聚合物在有氧和富离子环境下具有氧化还原活性，这一特性先前与儿茶酚基系统的抗菌行为有关。紫外-可见（UV-Vis）、傅里叶变换红外（FTIR）和质子核磁共振（1H NMR）谱图证实了该化合物的成功合成和儿茶酚的掺入。定量分析显示CCDP接枝效率约为29%。值得注意的是，ε-聚赖氨酸（EPL）的加入增强了涂层与各种底物的附着力，同时又不影响材料的固有抗菌活性。细菌生长曲线、最小抑菌浓度（MIC）和最小杀菌浓度（MBC）测定结果表明，EPL/PTC的MIC为0.31 mg/mL， MBC为1.25 mg/mL。此外，EPL/ ptc涂层硅橡胶表现出约85%的生物膜抑制率和76%的防污效率。通过在单一系统中结合防污和抗菌特性，该策略实现了传统表面处理中很少观察到的多功能性能。这些发现突出了EPL/PTC作为降低表面污染和感染风险的有前途的候选者，从而支持其在开发更安全的生物医学设备材料方面的潜在应用。

The performance of traditional packaging materials can no longer meet the requirements of the advanced semiconductor industry for high thermal conductivity and improved signal transmission rate. Therefore, the development of new polymer materials with both high thermal conductivity and low dielectric constant has become a huge challenge. A dual-regulation strategy was demonstrated, using ionic liquid as a “structure-directing agent” and magnesium oxide (MgO) as a thermal conductive filler. Through the strong interaction between the ionic liquid and the polymer main chain, further enhanced by MgO induced chain segment orientation and close packing. It integrates a porous membrane with excellent comprehensive performance, featuring a high thermal conductivity of 7.09 W∙m⁻¹∙K⁻¹ and a low dielectric constant of 1.45. Additionally, it boasts good thermal stability with a glass transition temperature (Tg) as high as 265 °C and excellent mechanical properties, with a tensile strength of up to 179.8 MPa. This dual regulation strategy is expected to be extended to other high performance polymer systems to achieve synergistic optimization of multiple properties, not just thermal and dielectric. This porous membrane demonstrates enormous potential as the next generation solution for electronic packaging, thermal management, and energy device applications.

传统封装材料的性能已经不能满足先进半导体工业对高导热性和提高信号传输速率的要求。因此，开发既具有高导热性又具有低介电常数的新型高分子材料已成为一项巨大的挑战。采用离子液体作为“结构导向剂”，氧化镁（MgO）作为导热填料，证明了一种双重调节策略。离子液体通过与聚合物主链的强相互作用，进一步增强了MgO诱导的链段取向和紧密堆积。它集成了一种综合性能优异的多孔膜，具有7.09 W∙m−1∙K−1的高导热系数和1.45的低介电常数。此外，它具有良好的热稳定性，玻璃化转变温度（Tg）高达265℃，机械性能优异，抗拉强度高达179.8 MPa。这种双重调节策略有望扩展到其他高性能聚合物体系，以实现多种性能的协同优化，而不仅仅是热学和介电性能。这种多孔膜作为下一代电子封装、热管理和能源设备应用的解决方案显示出巨大的潜力。

On-demand adhesion superhydrophilic/underwater superoleophobic coatings can significantly simplify the functionalization and regeneration processes of equipment surfaces, while also offering significant economic benefits and environmental sustainability advantages. However, preparing superhydrophilic/underwater superoleophobic coatings that can simultaneously satisfy high adhesion and on-demand adhesion remains a critical challenge. In this study, an on-demand adhesion, self-healing superhydrophilic/underwater superoleophobic coating (EDPE) based on nonwoven fabric was designed and fabricated by integrating the temperature-responsive mechanism of tardigrades with the superhydrophilic properties of fish mucus through a multi-level biomimetic structure. The produced EDPE coating retained its structural integrity and underwater superoleophobicity after 160 friction cycles and immersion in complex water environments (pH=2, pH=12, and artificial seawater), achieving self-healing and the restoration of underwater superoleophobicity in complex water environments. The coating also exhibited excellent adhesion properties on various materials, as well as repeatable adhesion and retention of its underwater superoleophobic performance through temperature response, offering outstanding resistance to external forces and environmental changes. In addition, the coating demonstrated excellent antifouling, drag reduction, and antibacterial properties. Notably, this work proposed a simple and effective design strategy for on-demand adhesion and self-healing superhydrophilic coatings. The approach could enable scalable manufacturing processes, offering new insights for industrial applications requiring advanced surface engineering solutions.

随需附着力的超亲水/水下超疏油涂层可以显著简化设备表面的功能化和再生过程，同时也具有显著的经济效益和环境可持续性优势。然而，制备同时满足高附着力和按需附着力的超亲水/水下超疏油涂层仍然是一个关键的挑战。本研究将水熊虫的温度响应机制与鱼黏液的超亲水特性结合起来，通过多层次的仿生结构，设计并制备了一种基于无纺布的随需粘附、自修复的超亲水/水下超疏油涂层（EDPE）。制备的EDPE涂层在复杂水环境（pH=2、pH=12和人工海水）中经过160次摩擦循环和浸泡后，仍保持了结构的完整性和水下超疏油性，在复杂水环境中实现了自修复和水下超疏油性的恢复。该涂层在各种材料上也表现出优异的粘附性能，并通过温度响应可重复粘附并保持其水下超疏油性能，具有出色的抵抗外力和环境变化的能力。此外，该涂层还具有优异的防污、减阻和抗菌性能。值得注意的是，这项工作提出了一种简单有效的按需粘附和自修复超亲水涂层设计策略。该方法可以实现可扩展的制造工艺，为需要先进表面工程解决方案的工业应用提供新的见解。

The oil and gas industry suffers severe risks from the synergistic damage of CO₂ corrosion and microbiologically influenced corrosion. However, traditional separate application of corrosion inhibitors and biocides faces drawbacks like chemical incompatibility, high costs and environmental pollution. To address this challenge, an eco-friendly ionic liquid, N-benzyl-1-((4,6-diamino-1,3,5-triazin-2-yl) amino)-3-mercapto-1-oxopropan-2-aminium (MC-B), was synthesized from low-cost cysteine and melamine via streamlined processes. MC-B exhibited prominent synergistic corrosion inhibition and antimicrobial performance based on a combination of electrochemical measurements, surface characterizations and molecular simulations. Endowed with abundant amino groups, MC-B presented high adsorption energy on steel surfaces, forming a dense protective film. At an optimal concentration of 25 ppm, it achieved a corrosion inhibition efficiency of up to 97.51% via mixed-type inhibition mechanism, and reduced both sessile and planktonic D. nigrificans cells by over two logarithmic units. This research offers a green, high-efficiency solution for the synergistic prevention and control of oilfield pipeline corrosion and microbial contamination, with considerable potential for industrial application.

Composite and multilayered forms of biodegradable packaging are manufactured in order to improve the qualities of the films. This kind of packaging has gained attention as a consequence of the problem of plastic waste. Natural pigments alter the color of packaging films as a result of pH changes due to components released during food deterioration, thus providing information about the food's status and functioning as intelligent packaging. This review covers the recent studies on the use of natural pigments for the production of biodegradable composite and multilayer intelligent packaging. In addition, a coating-design perspective is adopted to examine how layer structure, pigment incorporation, and polymer–pigment interactions shape the functional performance of multilayer and composite films. The review emphasizes structure property relationships central to coating science by summarizing key characterization techniques including mechanical, barrier, optical, and thermal analyses and explaining how natural pigment incorporation modifies the performance of multilayer and composite films. The possibilities of using biodegradable films containing natural pigments as spoilage indicators in food packaging are also summarized. The selection of appropriate biopolymers and pigments is important for the production of a high-quality film that can act as an indicator at the desired pH. Overall, this review integrates advancements in intelligent biodegradable packaging with principles of organic coating technology, outlines current challenges associated with pigment stability and coating durability, and highlights future research directions for developing scalable, high-performance functional coatings.

Wood materials are vulnerable to degradation induced by multiple biotic and abiotic factors, and surface coating serves as the most straightforward protective approach. However, traditional petroleum-derived coatings pose environmental risks and exhibit poor biodegradability. Consequently, the development of bio-based coatings has attracted extensive research attention. Lignin, the world's second most abundant organic polymer, exhibits potential to enhance coating properties such as UV resistance, mechanical strength, and durability due to its inherent chemical structure. Nevertheless, challenges in lignin application include poor dispersibility and inadequate interfacial compatibility. This review systematically summarizes progressive modification strategies to enhance lignin's hydrophobicity, environmental durability, and stability, thereby improving its utilization efficiency. Finally, it outlines recent research progress on lignin as a coating material and multifunctional filler.

Passive radiative cooling (PRC) technology offers a sustainable cooling approach for buildings without energy consumption. However, traditional polymer-based PRC materials are limited by environmentally harmful preparation techniques, poor substrate compatibility, and low recyclability. To address these challenges, this study innovatively presents an ethyl cellulose (EC)-based PRC coating prepared via an eco-friendly non-solvent-induced phase separation (NIPS) method. Owing to the hierarchical micro-nano porous structure and strong molecular vibrations, the coating demonstrates an ultrahigh solar reflectance of 0.96 and a mid-infrared emissivity of 0.96, resulting in a notable cooling effect of 8.3 °C. Importantly, the coating exhibits excellent compatibility with diverse building substrates, including wood, glass, textiles, plastics, metals, and tiles, enabling broad application across various architectural components.

This study provides a promising strategy for addressing the limitations of traditional polymer-based PRC materials and facilitates the development of energy-efficient buildings.

被动辐射冷却（PRC）技术为建筑提供了一种无能耗的可持续冷却方法。然而，传统的聚合物基PRC材料受到对环境有害的制备技术、衬底兼容性差和可回收性低等限制。为了解决这些挑战，本研究创新地提出了一种基于乙基纤维素（EC）的PRC涂层，该涂层采用环保的非溶剂诱导相分离（NIPS）方法制备。该涂层具有微纳分层多孔结构和强烈的分子振动，具有0.96的超高太阳反射率和0.96的中红外发射率，具有8.3℃的显著冷却效果。重要的是，该涂层与各种建筑基材（包括木材，玻璃，纺织品，塑料，金属和瓷砖）具有出色的兼容性，可以广泛应用于各种建筑组件。此外，涂层可以使用简单的乙醇/水溶剂系统回收，即使在多次回收循环后也能保持其冷却性能。这项研究为解决传统聚合物基PRC材料的局限性提供了一个有希望的策略，并促进了节能建筑的发展。

The development of high-performance hydrogen barrier films is crucial for ensuring the safety and integrity of hydrogen energy infrastructure. This study presents a novel strategy to significantly enhance the hydrogen barrier properties of polyvinyl alcohol (PVA) films by constructing a synergistic covalent and non-covalent bonding network. Maleic acid (MA) was employed as a dual-functional agent to crosslink PVA chains and covalently bridge them with MgAl-Layered Double Hydroxide (LDH) nanosheets via esterification. This molecular-level design resulted in a dense composite film with superior properties. The optimized PVA/0.5LDH/15MA film exhibited an ultra-low hydrogen gas transmission rate of 1.439 ± 0.027 cm³/(m²·day·atm), which is 73 % lower than that of pristine PVA. It also demonstrated excellent mechanical performance, with a tensile strength of 53 MPa and an elongation at break of 370.71 %. This work provides a promising material solution for enhancing safety in hydrogen applications and offers a new paradigm for designing high-barrier polymer composites through interface engineering.

Motivated by the demand for enhanced coating toughness and self-healing capabilities in polar low-temperature environments, a pH-responsive active filler, which was named as PDA@BTA@MOF, was synthesized through the layer-by-layer self-assembly of a metal–organic framework (MOF), benzotriazole (BTA) corrosion inhibitor molecules, and polydopamine (PDA). And then, the obtained fillers denoted as, was incorporated into an epoxy resin to prepare a composite coating (termed the PDA coating) that exhibited superior toughness and excellent low-temperature corrosion protection. Physicochemical characterization revealed that the PDA@BTA@MOF filler possesses a core-shell structure with cubic BTA@MOF as the core and PDA nanoparticles forming the shell, and the special structure ensure that the PDA@BTA@MOF filler could uniformly disperse within the PDA coating matrix. The active filler could significantly enhance the toughness, barrier properties against corrosive media penetration, and adhesion under various conditions of the PDA coating, primarily attributed to mechanisms such as the “pinning effect”. Electrochemical impedance spectroscopy (EIS) and salt spray tests reveals that the PDA coating containing PDA@BTA@MOF filler possesses more excellent anti-corrosion resistance that the pure epoxy coating (EP coating). Even under harsh alternating freeze-salt spray test conditions, where the diffusion of corrosive media through the is coating significantly accelerated and adhesion was substantially degraded, the PDA coating maintained remarkable protective efficacy. Furthermore, immersion tests and EIS analysis on scratched samples confirmed the pH-responsive release behavior of the PDA@BTA@MOF particles and the effective self-healing functionality of the PDA coating.

为了提高涂层在极低温环境下的韧性和自愈能力，通过金属有机骨架（MOF）、苯并三唑（BTA）缓蚀剂分子和聚多巴胺（PDA）的层层自组装，合成了一种ph响应活性填料，命名为PDA@BTA@MOF。然后，将得到的填料（记为）掺入环氧树脂中，制成具有优异韧性和低温防腐性能的复合涂层（称为PDA涂层）。理化表征表明，PDA@BTA@MOF填料具有以立方BTA@MOF为核心，PDA纳米粒子形成外壳的核壳结构，特殊的结构保证了PDA@BTA@MOF填料能够均匀分散在PDA涂层基体内。活性填料可以显著提高PDA涂层的韧性、抗腐蚀介质渗透的阻隔性能和在各种条件下的附着力，主要是由于“钉住效应”等机制。电化学阻抗谱（EIS）和盐雾测试表明，含有PDA@BTA@MOF填料的PDA涂层比纯环氧涂层（EP涂层）具有更优异的耐腐蚀性。即使在严酷的冻盐交替喷雾试验条件下，腐蚀介质在涂层中的扩散速度明显加快，附着力明显降低，PDA涂层仍保持着显著的防护效果。此外，对划伤样品的浸泡测试和EIS分析证实了PDA@BTA@MOF颗粒的ph响应释放行为和PDA涂层的有效自修复功能。

Anticorrosive coatings serve as the core protective measure for offshore wind power installations to resist the extreme corrosive marine environment, ensure the safe and stable operation of equipment, and control the whole-life-cycle costs. Organic coating protection is a cost-effective and convenient method. However, single-functional organic coatings are often insufficient to meet practical application requirements. Therefore, this study developed a multifunctional coating integrating self-healing properties, high mechanical performance, and corrosion resistance. By introducing bis(4-hydroxyphenyl) disulfide and furil as chain extenders and selecting bismaleimide as a cross-linking agent, a PU coating (PU-SS-DA) was successfully prepared. Additionally, a modified boron nitride filler (Mi-hBN-OH) was designed and incorporated into the PU coating to enhance its self-healing and anti-corrosion performance, resulting in the PU@BN coating. The PU-SS-DA, which combines triple dynamic bonds, exhibits outstanding tensile strength (20.88 MPa) and toughness (84.93 MJ·m⁻³), along with excellent self-healing performance. The coating achieved a repair rate of nearly 90 % after 4 h at 80 °C. Due to the synergistic effect of multiple dynamic bonds and the addition of modified boron nitride filler, the PU@BN coating with 5 % Mi-hBN-OH filler demonstrated the highest |Z|_f=0.01Hz value, reaching 3.23 × 10⁹ Ω·cm². After 28 days of immersion in saline, its |Z|_f=0.01Hz remained at 6.28 × 10⁹ Ω·cm². This study provides a new approach for designing polyurethane coatings with anti-corrosion, self-healing, and high mechanical performance properties.

防腐涂料是海上风电装置抵御极端腐蚀性海洋环境、保证设备安全稳定运行、控制全寿命周期成本的核心防护措施。有机涂层保护是一种既经济又方便的方法。然而，单一功能的有机涂料往往不能满足实际应用的要求。因此，本研究开发了一种集自愈性能、高机械性能和耐腐蚀性于一体的多功能涂层。通过引入双（4-羟基苯基）二硫化物和呋喃作为扩链剂，选择双马来酰亚胺作为交联剂，成功制备了PU涂层（PU- ss- da）。此外，设计了一种改性的氮化硼填料（Mi-hBN-OH）并将其掺入PU涂层中，以增强其自愈和抗腐蚀性能，从而得到PU@BN涂层。PU-SS-DA具有优异的抗拉强度（20.88 MPa）和韧性（84.93 MJ·m−3），并具有良好的自愈性能。在80℃下，经过4小时的修复，涂层的修复率接近90%。由于多个动态键的协同作用和改性氮化硼填料的加入，掺5% Mi-hBN-OH填料的PU@BN涂层|Z|f=0.01Hz值最高，达到3.23 × 109 Ω·cm2。在生理盐水中浸泡28天后，其|Z|f=0.01Hz保持在6.28 × 109 Ω·cm2。本研究为设计具有防腐、自愈和高力学性能的聚氨酯涂料提供了新的途径。
