The SiHTNR was prepared by grafting (3-mercaptopropyl) trimethoxysilane (MPTMS) to the hydroxyl telechelic natural rubber oligomers backbone (HTNR) issued from natural rubber, by thio-ene click reaction. The chemical structure of SiHTNR was confirmed by ¹HNMR and ²⁹SiNMR spectroscopy. The SiHTNR was used to successfully synthesize silane-functionalized WPU(SiWPU). The effect of nanosilica (SiO₂) content was studied on the morphology of SiWPU/SiO₂ particles and the mechanical properties, wettability and thermal properties of films. The TEM image indicated that siloxane functional group was successfully incorporated into the SiHTNR and showed interactions in silica-silica particles and the silica-SiWPU matrix, leading to a larger particle size with increasing nanosilica content. In addition, SiWPU/SiO₂ could form films and gave a more opaque yellow film with increasing nanosilica content. The tensile strength and thermal stability of SiWPU/SiO₂ films was improved and showed that single Tg and shifted toward higher temperature indicating the compatibility of nanosilica particles and confirmed stiffness characteristics of films with increasing nanosilica content. Finally, it was found that the efficacy of silver nanoparticles, chitosan, and sorbic acid to inhibit growth of <em>E. coli, S. aureus</em> and <em>V. parahaemolyticus</em> depends on the type and content of antibacterial agent. The minimum content of silver nanoparticles, chitosan, and sorbic acid to efficiently inhibit at least of 70 % of bacteria growth was 500 ppm, 200 ppm and 4800 ppm, respectively. However, the inhibition of <em>E. coli</em> growth required high contents of chitosan (600 ppm), while the inhibition of <em>S. aureus</em> required 8000 ppm of sorbic acid<em>.</em> Additionally, the release of these three types of antibacterial agents was investigated in the artificial seawater for 28 days. The behavior of silver nanoparticles and chitosan release showed increasing slope lines until day 14 while sorbic acid release showed increasing slope lines until day 7. After 28 days, the ratio of releasing content to antibacterial agent were 0.438:500Ag, 0.277:1600SB and 0.504:200CS. Comparatively, chitosan exhibits effective inhibiting <em>E. coli, V. parahaemolyticus</em> and <em>S. aureus</em> bacteria growth with a lower dose content, which is suitable for coating.

To address these issues, we propose a natural composite coating system integrating hyaluronic acid (HA), glycerol (Gly), FeCl₃, and zinc oxide nanoparticles (ZnO-NPs) via a facile mixing strategy. Inspired by the mucin-mediated hydration dynamics of tear films, the HA framework constructs a self-replenishing layer to inhibit fogging while achieving underwater oleophobicity through surface hydration, effectively repelling oily contaminants. Glycerol maintains flexibility and hydration equilibrium through hydrogen-bonded water retention, whereas FeCl₃ crosslinking enhances mechanical strength and water stability via dynamic coordination bonds emulating tear film's ion-modulated self-repair, thereby resisting hydration-induced degradation. ZnO-NPs further endow the coating with photo-induced hydrophilicity. The optimized coating exhibits exceptional water resistance, weathering durability, and mechanical robustness, retaining high transmittance and stable hydrophilicity after 120 h of water immersion, 120 h of xenon lamp irradiation, 40 adhesion cycles, and 300 abrasion tests.

However, the inherent hydrophilicity of this polymer results in moisture absorption, which leads to performance degradation in humid environments. Furthermore, the whitening of EVOH films often occurs during solution casting, which limits their applicability. To address these drawbacks, EVOH films were chemically modified by crosslinking with boric acid (BA). The introduction of BA controlled the crystallinity and promoted polymer chain rearrangement, thereby reducing the degree of structural heterogeneity and enhancing the barrier, mechanical, and optical performances. Additionally, EVOH/BA films were fabricated with different BA concentrations (0, 1, 3, and 5 wt%). In the absence of BA and at a low BA concentration of 1 wt%, the film exhibited significant whitening owing to mesophase accumulation and the formation of porous structures. Upon increasing the BA content, the degree of film whitening progressively diminished, with a fully transparent film being obtained at a BA concentration of 3 wt%. The enhanced crosslinking density at this concentration also contributed to an improved barrier performance, thermal stability, and mechanical strength. However, a slight decline in performance was observed at a higher BA concentration of 5 wt% owing to excessive crosslinking. Based on these results, a 3 wt% BA concentration was considered optimal. This work represents a simple yet effective strategy for improving the structural integrities and functional performances of solution-cast EVOH films, offering practical potential for advanced packaging applications.</div></div>","PeriodicalId":20834,"journal":{"name":"Progress in Organic Coatings","volume":"208 ","pages":"Article 109533"},"PeriodicalIF":6.5,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144678832","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 durable superhydrophobic photothermal anti-icing (SPAI) surface was fabricated on aluminum (Al) using SiC and carbon particles (CS) via a two-step spraying process. The SPAI surface was fabricated by applying an epoxy resin layer on aluminum surface, followed by spraying a mixture of modified SiC, and CS with polydimethylsiloxane (PDMS).
