The synergistic effects of dispersing various percentages of g-C₃N₄ nanosheets on the mechanical robustness and anticorrosion performance of epoxy resin were extensively studied. The structures, sizes, and morphologies of proposed polymeric nanocomposites and nanofillers were investigated using several characterization techniques. The epoxy/g-C₃N₄ nanocomposites were filmed as coating layers using an air-assisted spray technique. The mechanical durability was evaluated using impact, T-bending, and cross-hatch test techniques. Electrochemical experiments (in a solution of 3.5 % NaCl) and a salt spray test for 500 h (according to ASTM B-117) were conducted on the coated carbon steel to evaluate the anticorrosion performance. The results indicated that the well-distributed epoxy/g-C₃N₄ (1 wt%) nanocomposite exhibited the highest surface elasticity, mechanical durability, and corrosion-resistant properties (R_ct = 428.3 Ω cm² × 10³) with corrosion-inhibition efficiency percentage (ɳ_p) of 92.04 %. It exhibited the highest abrasion resistance (very low mg loss for 500 cycles) and outstanding pull-off measurement (12.6 MPa). The salt spray test on the coated carbon steel samples for 500 h showed minimized blister and rusting density and confirmed the corrosion-prevention of the well-distributed epoxy/g-C₃N₄ nanocomposite.

This study proposes a synergistic antifouling strategy combining both active and passive mechanisms, thereby achieving efficient and eco-friendly antifouling performance. Specifically, we designed and synthesized porous ruthenium selenide nanoparticles (P-RuSe₂ NPs) with dual enzyme-like activities (peroxidase and photoactivated oxidase), and combined them with a low-surface-energy coating to construct an antifouling system that integrates both active and passive synergistic functions. In this system, the low-surface-energy coating provides passive protection by reducing the initial attachment of biofouling organisms, while the P-RuSe₂ NPs actively kill bacteria through their excellent enzymatic catalytic activity, further enhancing the antifouling effect. After 180 days of marine immersion, the biofouling area of the coating was reduced by 86.22 % compared to the control sample, demonstrating exceptional long-term antifouling performance.

However, all microstructured surfaces face the common problem of poor durability, which limits the development of bionic microstructures. While the microstructures of plants and animals are also fragile, they are able to maintain their integrity through biological processes such as metabolism. Inspired by biological metabolism, this paper proposes a novel approach to constructing microstructured surfaces. By utilizing the differences in wear resistance between different materials in the coating, microstructures are continuously generated on the surface during friction, allowing for the continuous renewal of the microstructure during wear, ensuring the integrity of the surface microstructure and function. The coating formed by the combination of different materials not only achieves sustainable microstructure but also combines the superhydrophobicity of lotus leaves, the anti-adhesive properties of shark skin, and the “brick-and-mortar” structure of nacre, which effectively enhance the antifouling and anticorrosion performance of the coating. Based on this concept, an EP-PE superhydrophobic coating was developed using epoxy resin and polyethylene, exhibiting high mechanical properties as well as effective antifouling and anticorrosion capabilities.

Some modifiers must undergo specific activation processes to achieve their full potential. Amide waxes are chemically characterized by their long-chain fatty acid structures and amide functional groups. Upon dissolving, the wax molecules align in fibrillar forms by intermolecular forces, and the consecutive network of fibrils increases viscosity. This study aims to identify the parameters influencing the activation of amide wax and propose an optimal activation method. The impact of polar solvents on amide wax's solubility and the resulting gel's structure was examined. Ethanol emerged as one of the most effective polar solvents, although optimal concentration is necessary; excessive amounts negatively affect solubility and lead to fractal gels beyond a certain concentration. Additionally, heat significantly influences activation, as higher temperatures are required for the dissolution of amide wax. Rheological curves indicate that amide wax molecules behave differently at elevated temperatures, depending on the presence of polar solvents. The study found that using an inline disperser is the most effective activation method, as it generates high shear rates to mechanically disperse the amide wax and produces heat to facilitate dissolution. Furthermore, the sagging limit of the paint film varied between 250 and 400 μm based on the activation method, despite maintaining a constant amount of amide wax. This finding suggests that optimal activation allows for achieving the desired film thickness with a reduced quantity of rheological additives.</div></div>","PeriodicalId":20834,"journal":{"name":"Progress in Organic Coatings","volume":"204 ","pages":"Article 109278"},"PeriodicalIF":6.5,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143748480","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
