Superhydrophilic separation materials, with their high separation efficiency, low energy consumption, and absence of secondary pollution, have emerged as an ideal solution. Within these materials, demulsification and anti-fouling strategies are central to achieving efficient emulsion separation. However, solely enhancing demulsification capability enables high-efficiency separation in the short term, yet insufficient anti-fouling capacity leads to fouling, causing sudden flux decline. Conversely, merely improving anti-fouling ability can maintain stable flux, but inadequate demulsification results in low separation efficiency. Therefore, synergistically enhancing both demulsification and anti-fouling is crucial to achieving stable and long-lasting separation. Despite extensive recent progress, comprehensive reviews integrating demulsification and anti-fouling remains relatively scarce. This review aims to address this urgent need, focusing specifically on membrane-type superhydrophilic materials. It provides an in-depth analysis of the advances in their demulsification and anti-fouling strategies. First, it introduces the fundamental mechanisms governing surface wettability regulation. Subsequently, from a performance perspective, it outlines the key factors and parameters influencing separation effectiveness. Building upon a comprehensive summary of recent strategies for enhancing demulsification and anti-fouling capabilities and their underlying mechanisms, this review objectively analyzes the prevalent challenges and limitations of current approaches. Finally, it provides valuable guidance for the future design and optimization of advanced oil-water separation materials.</div></div>","PeriodicalId":20834,"journal":{"name":"Progress in Organic Coatings","volume":"210 ","pages":"Article 109638"},"PeriodicalIF":7.3,"publicationDate":"2025-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145004984","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, a flame-retardant antibacterial multifunctional agent, AMOTP, was synthesized through the polymerization of phosphorus oxychloride and diethylenetriamine, followed by the introduction of guanidine-based antibacterial groups. Subsequently, a durable, highly efficient, halogen-free, and formaldehyde-free multifunctional cotton fabric was prepared using a one-step process. When the weight gain rate was 16.8 %, the AMOTP-treated cotton fabric (C3) demonstrated a reduction of 87.98 % and 42.97 % in the peak heat release rate (PHRR) and total heat release (THR), respectively. Moreover, the LOI value of C3 was 43.4 %, with antibacterial rates of 99.99 % against both <em>E. coli</em> and <em>S. aureus</em>.

In this work, a dual-functional slippery organogel coating was meticulously synthesized by introducing Ag(Ӏ)-imine coordination bonds into organosilicon networks, thereby endowing the coating with self-healing and antibacterial properties. A surface scratch with a width of 50 μm can be effectively repaired within 6 h at 60 °C, and the repair efficiency exceeds 85 %.

Given the limitations of current grinding and classification technologies in meeting industrial requirements, a method has been developed for narrowing PSD through modifying the classifier impeller of an air classifier mill (ACM) by installing a wire mesh. It is found that when the particle size is adjusted by individually varying the three operating parameters, the installation of wire mesh on the classifier impeller effectively reduces the particle size span and thus enhances classification accuracy in the ACM. This improvement is attributed to the mesh's increasing resistance to airflow and suppressing macro-scale vortices, generating micro-scale vortices that induce particle rotation which leads to more hydrodynamic-spherical particle characteristics, and further enhancing classification through the mesh's quasi-sieving function. Changes in mesh pore size exert the strongest influence on classification performance when particle size is controlled via impeller frequency adjustment. After mesh installation, the improvement in classification performance is more pronounced for products with larger particle sizes. By quantitatively evaluating the effects of operating parameters and mesh pore size on PSD, it is demonstrated that adjusting classifier impeller and fan frequencies is a more effective strategy for producing powders with a narrow PSD. Through investigation of the combined effects of classifier impeller and fan frequencies, an optimal operating range is identified that minimizes span for a given particle size and delineates the corresponding operating conditions. Finally, the results demonstrate that powders produced with a mesh-affixed impeller exhibit significantly enhanced flowability and improved coating-film appearance compared to powders produced with the original impeller.</div></div>","PeriodicalId":20834,"journal":{"name":"Progress in Organic Coatings","volume":"210 ","pages":"Article 109634"},"PeriodicalIF":7.3,"publicationDate":"2025-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144997494","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

TiO₂ nanoparticles were prepared by a controlled hydrolysis–condensation process using titanium tetra butoxide (TBOT) as precursor, while g-C₃N₄ was synthesized through thermal polymerization of melamine with a pre-saturation step to improve its crystallinity and surface reactivity. The resulting g-C₃N₄ nanosheets were then decorated with TiO₂ nanoparticles to form a hierarchical heterojunction, followed by surface functionalization with 3-aminopropyltriethoxysilane (APTES) via a silanization treatment. This strategy enabled excellent nanofiller dispersion, strong filler–matrix interaction, and scalable integration into an acrylic resin matrix. UV–Vis diffuse reflectance spectroscopy and Tauc plot analysis revealed a bandgap narrowing to 2.55 eV in the functionalized heterostructure, facilitating visible-light activation. The hybrid exhibited significantly suppressed photoluminescence intensity and a threefold increase in transient photocurrent density, indicating improved charge separation. Electrochemical impedance spectroscopy confirmed reduced interfacial resistance, enhancing charge transport across the coating interface. Colorimetric analysis showed superior methylene blue (MB) dye degradation under UV (Δb* = 40) and visible light (Δb* = 42), compared to neat acrylic resin (Δb*˂ 3.5). ESR and scavenger studies identified photogenerated holes as dominant species, assisted by ·OH and ·O₂⁻ radicals.

To address this issue, we have successfully developed a multifunction integrated coating (anti-reflective, light-converting coating; abbreviated to ARLC-Coating) by combining an anti-reflective layer (AR-layer) with a light conversion film (LC-layer) using a facile method.

Moreover, the nano-array structure and low surface energy of the AR-layer, combined with its strong adhesion with the LC-layer, endow the ARLC-Coating with exceptional thermal insulation, dust resistance, mechanical robustness, and all-weather durability.
