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. This combination of interactions significantly improves the coating's mechanical robustness.

To extend the repair capability of PANI fibers to large damaged areas, we propose entrapping neutral corrosion inhibitors within the PANI fibers. This was achieved by preparing benzotriazole (BTA)-entrapped HCl or sulfosalicylic acid (SSA)-doped PANI fibers through a one-step chemical oxidative polymerization process. The effects of various counterions and neutral inhibitors on corrosion protection were explored. 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.
