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. Building energy simulations further demonstrate Janus film's significant cooling energy savings across global climates. With superior mechanical robustness, environmental stability, and adaptive thermal management, this Janus coating film offers strong potential for building energy conservation, wearable electronics, and outdoor applications.

不断升级的全球能源危机和电磁污染对可持续性和人类健康构成双重威胁。因此，开发用于零能量冷却和有效电磁干扰屏蔽的多功能材料至关重要。本文基于高速剪切和超声分散，采用溶剂蒸发和湿度辅助相分离相结合的可扩展方法制备了可拉伸Janus涂层。该薄膜集被动辐射冷却、电磁干扰屏蔽、焦耳加热、自清洁和阻燃于一体。辐射冷却层由热塑性聚氨酯基体与BaSO4微纳米颗粒和SiO2-HA填料组成，形成多尺度多孔结构，利用Mie散射、多次反射和声子极化子共振实现高太阳反射率（90.46%）和发射率（95.71%）。它还具有超疏水性（CA > 150°）和低导热性。采用石墨烯基致密多孔梯度构建的电磁干扰层，解决了以石墨烯为填充材料结合高屏蔽效率和优异力学性能的顽固性问题。它采用吸收-反射-吸收机制，平均屏蔽效率为36.07 dB （x波段），并在7 V下快速电热加热至93.3°C。无卤磷添加剂提供自熄阻燃性，薄膜保持优异的柔韧性（应变243%）。室外测试表明，白天亚环境冷却平均为5.5°C，理论冷却功率为84.27 W/m2。建筑能源模拟进一步证明了Janus薄膜在全球气候下显著的制冷节能效果。凭借卓越的机械稳健性，环境稳定性和自适应热管理，这种Janus涂层薄膜为建筑节能，可穿戴电子产品和户外应用提供了强大的潜力。

The ability of polyunsaturated vegetable oils to form solid polymer films by oxygen-induced radical polymerization explains their major role as binders in paints and coatings. However, at large film thicknesses, the diffusion of the oxygen in the bulk is limited which induces gradients of composition and surface instabilities in the film. To avoid this effect, in industrial applications the oil is first prepolymerized, or blown, at high temperature. Here we show that millimeter-thick coatings may be produced by oxidative thermal curing of conjugated polyunsaturated free fatty acids without addition of any catalyst. These free fatty acids (FA) are produced by enzymatic hydrolysis of biobased triglycerides (TG) from Ricinodendron heudelotii oils rich in α-eleostearic acid (18:3). While both the crude oil (TG) and the free fatty acids (FA) are transformed into rubbery polyester networks insoluble in organic solvents, the FA samples show much less surface instabilities. Using infrared spectroscopy and differential scanning calorimetry, we reveal the pathway of the network formation in the TG and FA upon polymerization. By rationalizing these results in comparison with dynamic mechanical analysis of FFA polyesters, we suggest the possible network formation mechanism which may explain lower surface instabilities of the FA samples with respect to the TG ones.

多不饱和植物油通过氧诱导自由基聚合形成固体聚合物薄膜的能力解释了它们在油漆和涂料中作为粘合剂的主要作用。然而，在大的薄膜厚度下，氧在体中的扩散受到限制，这导致了薄膜中的成分梯度和表面不稳定性。为了避免这种影响，在工业应用中，油首先在高温下预聚合或吹制。本研究表明，在不添加任何催化剂的情况下，共轭多不饱和游离脂肪酸可以通过氧化热固化制备毫米厚的涂层。这些游离脂肪酸（FA）是由富含α-骨脂酸的蓖麻籽油酶解生物基甘油三酯（TG）产生的（18:3）。虽然原油（TG）和游离脂肪酸（FA）都转化为不溶于有机溶剂的橡胶聚酯网络，但FA样品的表面不稳定性要小得多。利用红外光谱和差示扫描量热法，揭示了聚合过程中TG和FA的网络形成途径。通过将这些结果与FFA聚酯的动态力学分析进行比较，我们提出了可能的网络形成机制，这可能解释了FA样品相对于TG样品表面不稳定性较低的原因。

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.

石油和天然气行业面临着CO 2腐蚀和微生物影响腐蚀协同破坏的严重风险。然而，传统的缓蚀剂和杀菌剂单独应用存在化学不相容性、成本高、环境污染等缺点。为了解决这一挑战，以低成本半胱氨酸和三聚氰胺为原料，通过流线型工艺合成了一种环保离子液体n-苄基-1-（（4,6-二氨基-1,3,5-三嗪-2-基）氨基）-3-巯基-1-氧丙基-2-胺（MC-B）。结合电化学测量、表面表征和分子模拟，MC-B表现出突出的协同缓蚀和抗菌性能。MC-B具有丰富的氨基，在钢表面表现出较高的吸附能，形成致密的保护膜。在最佳缓蚀浓度为25 ppm时，通过混合型缓蚀机制，其缓蚀效率可达97.51%，对无根型和浮游型黑木霉细胞的缓蚀效果均优于2个对数单位。本研究为油田管道腐蚀和微生物污染的协同防治提供了一种绿色、高效的解决方案，具有较大的工业应用潜力。

Marine antifouling coatings are critical for protecting ships and offshore industrial equipment from biofouling and corrosion. However, conventional coatings often fail to balance antifouling and anti-corrosion performance with mechanical stability. In this paper, a pH-responsive antibiofouling composite coating (OC-MCSX) with slippery liquid-like properties and long-term functionality was developed. The coating was fabricated by covalently grafting PDMS brushes into an epoxy matrix via thermal crosslinking, while incorporating microencapsulated 4,5-dichloro-2-n-octyl-4-isothiazolin-3-one (DCOIT) as a functional filler. The highly crosslinked network significantly enhanced the OC-MCSX's mechanical strength, whereas the pH-responsive microcapsules enabled precise controlled release of antifoulants. Furthermore, this design integrates a low-surface-energy fouling-release mechanism with a contact-inhibition antifouling strategy. Through the synergistic effects of surface interface regulation and controlled-release antifouling agents, it effectively suppresses the adhesion and accumulation of biofouling, thereby achieving stable and long-lasting antifouling performance. The experimental results showed that the composite coating with 3 wt% microcapsule loading (OC-MCS3) exhibited remarkable antibacterial efficacy, the antibacterial rates against E. coli and S. aureus are 98.25 % and 99.56 % respectively, inhibition rates of 88.22 % against chlorella and 93.13 % against diatoms, and a pseudo-barnacle removal strength of only 0.053 MPa. In addition, the coating exhibited excellent resistance to a wide range of solid and liquid contaminants, along with superior self-cleaning ability. After 60 days of marine immersion testing, the OC-MCS3 coating showed no significant biofouling coverage compared with control samples, confirming its excellent anti-fouling stability. This research proposes a prospective tactic for developing environmentally friendly and durable anti-fouling coatings for ships.

船舶防污涂料对于保护船舶和海上工业设备免受生物污染和腐蚀至关重要。然而，传统涂料往往不能平衡防污和防腐性能与机械稳定性。本文研制了一种ph响应型抗菌剂复合涂层（OC-MCSX），该涂层具有光滑的类液体特性和长效功能。该涂层通过热交联将PDMS电刷共价接枝到环氧树脂基体上，并加入微胶囊化4,5-二氯-2-n-辛基-4-异噻唑啉-3- 1 （DCOIT）作为功能填料。高度交联的网络显著提高了OC-MCSX的机械强度，而ph响应微胶囊能够精确控制防垢剂的释放。此外，该设计集成了低表面能污垢释放机制和接触抑制防污策略。通过表面界面调节和控释防污剂的协同作用，有效抑制生物污垢的粘附和积累，从而达到稳定持久的防污性能。实验结果表明，微胶囊负载量为3 wt%的复合涂层（OC-MCS3）具有显著的抗菌效果，对大肠杆菌和金黄色葡萄球菌的抑菌率分别为98.25%和99.56%，对小球藻和硅藻的抑菌率分别为88.22%和93.13%，对伪附体的去除强度仅为0.053 MPa。此外，该涂层对各种固体和液体污染物具有优异的抵抗能力，并具有优异的自清洁能力。经过60天的海水浸泡测试，与对照样品相比，OC-MCS3涂层没有明显的生物污垢覆盖，证实了其出色的防污稳定性。本研究为开发环境友好、耐用的船舶防污涂料提供了一种前瞻性策略。

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.

Introducing self-lubricating microdrops into a resin matrix is an effective strategy for developing advanced materials that combine efficient lubrication with durable impact wear resistance. In this paper, we prepared self-lubricating composite coatings (PU/LCG) by dispersing lithium composite grease (LCG) microdrops into a polyurea (PU) resin matrix. X-ray micro-computed tomography (micro-CT) revealed a three-dimensional network of PU-encapsulated LCG microdrops, which significantly enhanced lubrication efficiency and reduced oil depletion. The PU/LCG-10% coating showed dramatically improved tribological performance, with a 90.6% lower coefficient of friction and a 79.8% lower wear rate than the pure PU coating.

在树脂基体中引入自润滑微滴是开发先进材料的有效策略，该材料结合了有效的润滑和持久的抗冲击磨损性。本文将锂复合润滑脂（LCG）微滴分散到聚脲（PU）树脂基体中，制备了自润滑复合涂层（PU/LCG）。x射线微计算机断层扫描（micro-CT）显示了pu包封LCG微滴的三维网络，显著提高了润滑效率，减少了油的损耗。与纯PU涂层相比，PU/LCG-10%涂层的摩擦系数降低了90.6%，磨损率降低了79.8%。均匀分散、最佳尺寸的LCG微滴能够快速释放油，在摩擦界面形成润滑膜。PU/LCG-10%涂层还表现出高韧性（8.11 MJ/m3）和最小冲击磨损径（1.09 mm），表明其具有有效的抗操作冲击磨损能力。冲击耐磨性源于释放油过程中的能量吸收和应力分散，减轻了塑性变形。这种协同设计使PU/LCG涂层适用于各种自润滑机械系统。

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.

As the demand for flame-retardant materials grows, intumescent fire-retardant coatings (IFC) have attracted significant attention due to advantages such as ease of application, minimal impact on substrate properties, and high flame-retardant efficiency. However, conventional IFC exhibit limitations including low char strength and hygroscopic components. To address these issues, this study introduced low-melting-point glass powder (LMGP) as a ceramic-forming filler into IFCs, preparing a ceramicizable IFC (C-IFC) with higher char layer strength. Furthermore, TiO₂ was surface-modified with 1H,1H,2H,2H-perfluorodecyltriethoxysilane (PFDTS) to produce superhydrophobic PFDTS@TiO₂ powder. By combining the aforementioned coating and modified powder through a two-step process, a superhydrophobic ceramicizable IFC (C₂₀-IFC/ PFDTS@TiO₂) was successfully developed. This coating demonstrated excellent fire-retardant and thermal insulation performance on steel structures and rigid polyurethane foam (RPU).Additionally, the coating surface exhibited exceptional hydrophobicity, with a water contact angle (WCA) of 157.5 ± 0.7° and a water roll-off angle(WRA) of 4 ± 0.3°. This hydrophobic surface gives the coating excellent water resistance. This work provides a universal and efficient solution for developing high-performance, durable fire-retardant protective coatings integrating ‘fire and water non-invasion’ and self-cleaning capabilities.

随着阻燃材料需求的增长，膨胀型阻燃涂料（IFC）因其易于应用、对基材性能影响最小、阻燃效率高等优点而备受关注。然而，传统的IFC具有局限性，包括低炭强度和吸湿成分。为了解决这些问题，本研究将低熔点玻璃粉（LMGP）作为陶瓷成型填料引入到IFC中，制备了具有更高炭层强度的可陶瓷IFC （C-IFC）。然后用1H，1H,2H，2H-全氟癸基三乙氧基硅烷（PFDTS）对TiO2进行表面改性，制备超疏水PFDTS@TiO2粉体。通过两步法将上述涂层与改性粉末相结合，成功开发出超疏水可陶化IFC （C20-IFC/ PFDTS@TiO2）。该涂料对钢结构和硬质聚氨酯泡沫（RPU）具有优异的阻燃和隔热性能。此外，涂层表面表现出优异的疏水性，水接触角（WCA）为157.5±0.7°，水滚转角（WRA）为4±0.3°。这种疏水表面使涂层具有优异的耐水性。这项工作为开发高性能、耐用的防火防护涂料提供了一种通用和有效的解决方案，该涂料集“防火、防水”和自清洁能力于一体。

The development of bio-based composite coatings that balance mechanical integrity with water responsiveness remains a key challenge in sustainable material design. In this study, mineral–organic hybrid coatings were formulated using talc (lamellar inorganic filler) and eucalyptus wood powder (lignocellulosic fibrous filler) to investigate how the filler composition governs powder flowability, coating cohesion, and moisture-mediated functionality in Brassica napus L. seed pelleting. Distinct particle size distributions and hygroscopic properties of the fillers generated tunable densities and porosities across the talc–eucalyptus ratios. Increasing the organic fraction enhanced flowability and reduced apparent density. This shift was accompanied by a higher equilibrium moisture content and solubility, indicating increased hydrophilicity and improved moisture buffering. Mechanical testing showed that pure talc coatings were brittle and rapidly disintegrated, whereas mixtures containing 40–60 % eucalyptus achieved optimal compressive strength (4–5 N), high cracking resistance (>1200 s), and negligible crushing. Germination assays revealed that these intermediate formulations maintained high germination (88 %) and vigor, outperforming both mineral- and organic-dominated coatings. Cluster analysis confirmed that intermediate compositions formed coherent functional groups. Collectively, these results show that the controlled blending of mineral rigidity and organic flexibility enables the rational design of moisture-responsive, biodegradable seed coatings. All experiments were conducted under controlled laboratory conditions, and field-scale validation is required to confirm agronomic performance.

在可持续材料设计中，平衡机械完整性和水响应性的生物基复合涂层的开发仍然是一个关键挑战。在这项研究中，使用滑石粉（层状无机填料）和桉树木粉（木质纤维素纤维填料）配制了矿物-有机混合涂层，以研究填料成分如何影响甘蓝型油菜种子造粒中的粉末流动性、涂层粘聚性和水分调节功能。不同的粒径分布和填料的吸湿特性产生了可调的密度和孔隙率在滑石-桉树的比例。增加有机组分可提高流动性，降低表观密度。这种转变伴随着更高的平衡水分含量和溶解度，表明亲水性增加和水分缓冲改善。力学试验表明，纯滑石粉涂层易碎且易崩解，而含有40 - 60%桉树的混合物具有最佳抗压强度（4-5 N），高抗裂性（>1200 s），可忽略破碎。发芽试验表明，这些中间配方保持高发芽率（88%）和活力，优于矿物和有机为主的涂料。聚类分析证实中间成分形成了连贯的官能团。总的来说，这些结果表明，矿物刚性和有机柔韧性的可控混合能够合理设计水分响应，可生物降解的种子涂层。所有试验均在受控的实验室条件下进行，并需要进行田间规模验证以确认农艺性能。

The addition of corrosion inhibitors to epoxy resin coatings is an effective strategy of preventing corrosion process of the substrate. However, the anti-corrosion performance of epoxy resin coatings is not satisfactory in terms of long period of time, owing to the leaking out of corrosion inhibitors. In this paper, we present a composite epoxy resin coating with enhanced long-term anti-corrosion performance, achieved through the synergistic combination of inorganic and organic corrosion inhibitors that refer to metal-organic frameworks (MOFs) with controlled loading of benzotriazole (BTA). The complexation of the inorganic corrosion inhibitor Ce⁴⁺ within the UiO-67 structure (UiO-67-Ce) is accomplished by partially substituting organic ligands with Ce-coordinated 2,2′-bipyridine-5,5′-dicarboxylic acid (Bpydc-Ce). Then, organic corrosion inhibitor BTA is further incorporated into the UiO-67-Ce@BTA by solvent loading process. The organic and inorganic inhibitors-loaded MOFs are dispersed in the epoxy matrix to fabricate anti-corrosion coatings via spraying-coating method. The UiO-67-Ce@BTA/epoxy coating exhibits high corrosion inhibition efficiency (99.95 %), due to efficient release of the bifunctional inhibitors. Additionally, scratch test of the UiO-67-Ce@BTA/epoxy coating demonstrates active corrosion protection performance, which can effectively mitigate localized corrosion. Therefore, we establish an organic-inorganic synergistic anti-corrosion strategy using UiO-67-Ce@BTA as functional nanofillers, offering promising strategy for corrosion protection.

在环氧树脂涂层中添加缓蚀剂是防止基体腐蚀的有效方法。然而，由于缓蚀剂的泄漏，环氧树脂涂料的防腐性能在长时间内并不令人满意。在本文中，我们提出了一种复合环氧树脂涂层，具有增强的长期防腐性能，通过无机和有机缓蚀剂的协同组合，指的是金属-有机框架（MOFs）与控制负载苯并三唑（BTA）。无机缓蚀剂Ce4+通过ce配位的2,2′-联吡啶-5,5′-二羧酸（Bpydc-Ce）部分取代有机配体，与UiO-67结构（UiO-67- ce）进行络合。然后，通过溶剂加载工艺将有机缓蚀剂BTA进一步掺入UiO-67-Ce@BTA中。将负载有机和无机缓蚀剂的mof分散在环氧基体中，采用喷涂法制备防腐涂层。由于双功能抑制剂的有效释放，UiO-67-Ce@BTA/环氧涂层具有较高的缓蚀效率（99.95%）。此外，UiO-67-Ce@BTA/环氧涂层的划痕试验表明，该涂层具有有效的防腐性能，可以有效地减轻局部腐蚀。因此，我们建立了一种有机-无机协同防腐策略，以UiO-67-Ce@BTA为功能纳米填料，为防腐提供了有前途的策略。
