However, these multi-layer systems involve complex application and curing processes that generate more by-products, consume extra energy, and extend processing times which are impractical for industrial applications such as aeronautics and lead to increased environmental impacts. Furthermore, issues such as interlayer adhesion failure and aging may arise due to the distinct chemical nature of the layers, that can lead to severe defects and induce corrosion on airplanes. Reducing the number of layers while maintaining or enhancing performance is therefore critical. Self-stratifying coatings offer a promising solution by forming multilayer structures in a single application and curing step directly on various substrates. This approach simplifies the process and improves eco-efficiency by lowering material waste, energy consumption, and production time. In this paper, a self-stratified epoxy/thermoplastic polyurethane coating is designed for the first time. The use of a sulfur-containing compound as curing agent in the system leads to a less energy consuming process thanks to the reduction of the curing temperature compared to traditional amine curing agents. The presence of sulfur atoms also facilitates the layers differentiation in the self-stratified coating. Finally, excellent adhesion and mechanical properties are obtained, outperforming a conventional step-by-step bi-layer system. This self-stratifying coating is therefore very promising for aeronautical applications.</div></div>","PeriodicalId":20834,"journal":{"name":"Progress in Organic Coatings","volume":"208 ","pages":"Article 109478"},"PeriodicalIF":6.5,"publicationDate":"2025-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144471227","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}

Inspired by the general concept of natural superhydrophobic surfaces, a highly transparent superhydrophobic anti-icing composite coating based on a Polyvinylidene fluoride-trifluoroethylene (PVDF-TrFE)/Polydimethylsiloxane (PDMS) blend polymer via electrospinning technology has been developed. By constructing a PVDF-TrFE/PDMS nanofiber network on a silanized trimethylsilane (TMS-s) /polydimethylsiloxane (PDMS) promoter layer (which acts as an interface-strengthening layer), the gradient structure design of the functional coating on the glass substrate was successfully realized. Experimental results demonstrate that the TMS-s/PDMS promoter layer significantly enhances the interfacial bonding strength between the PVDF-TrFE/PDMS nanofibers and the glass substrate, achieving a water contact angle of 154.1° ± 4°, a sliding angle of 3° ± 1°, and approximately 92.6 % transmittance. The adhesion-enhancing mechanism is further investigated through molecular dynamics simulation analysis. Results reveal that the introduction of TMS-s increases interfacial adhesion, attributed to strong siloxane bonds formed between TMS-s and the glass surface, as well as Si-O-C bonds between TMS-s and PDMS.

To extend the repair capability of PANI fibers to large damaged areas, we propose entrapping neutral corrosion inhibitors within the PANI fibers.

A comprehensive release experiment examined unwashed and washed BTA-entrapped HCl or SSA-doped PANI fibers, confirming their pH-responsive controlled release capabilities. The results indicated that incorporating these fibers into polyvinyl butyral (PVB) coatings significantly enhances anti-corrosive performance compared to coatings without entrapped neutral corrosion inhibitors. Specifically, the low frequency impedance magnitude for PANI-SSA-BTA/PVB and PANI-HCl-BTA/PVB coatings increased by sixfold and elevenfold, respectively, over the pure PVB coating. This enhanced performance is attributed to the synergistic effect of the passivation of PANI fibers and the controlled release of BTA.

In this study, zinc oxide nanoparticles were synthesized using a green method involving mangrove plants and evaluated as a paint additive to control marine fouling on fish farming cages. The size and characteristics of zinc oxide nanoparticles were evaluated using XRD, FTIR, and TEM analyses. The effectiveness of the nanoparticles was assessed through antibacterial and antialgal tests, as well as by examining their lethal effects on two species, <em>Amphibalanus amphitrite</em> and <em>Artemia salina</em>, in laboratory settings. The minimum inhibitory concentration (MIC) of zinc oxide nanoparticles against the bacteria <em>Staphylococcus aureus</em> and <em>Escherichia coli</em> was determined to be 6.25 and 25 mg/L, respectively, after 48 h. At a concentration of 800 mg/L, zinc oxide nanoparticles inhibited the growth rates of the algae <em>Spirulina platensis</em>, <em>Dunaliella salina</em>, and <em>Chaetoceros muelleri</em> by 90.88 %, 94.06 %, and 92.49 %, respectively, demonstrating their high potential as an effective inhibitor. An epoxy resin paint containing 2 %, 4 % or 8 % zinc oxide nanoparticles was used as an antifouling solution. The tests were conducted in a sea environment at depths of 1 m, 5 m and 10 m below the surface, with the samples left for 90 days to evaluate their performance over time. Increasing the concentration of zinc nanoparticles in the paint enhanced its the antifouling performance of the paint increases. By the end of the experiment, seven groups of organisms were identified: Ascidiacea (1 species), Polychaeta (1 species), Gastropoda (2 species), Globothalamea (1 species), Tubothalamea (1 species), Thecostraca (1 species), and Bivalva (9 species).
