To tackle this issue, we propose an innovative strategy that involves surface modification of cellulose nanocrystals (CNC) using long-chain alkyl alcohols and the preparation of polyurethane composite films with excellent hydrophobicity by compounding the modified CNC (C-CNC) with waterborne polyurethane (WPU). Using a custom mold, we achieved surface hydrophobic functionalization. This study delves into the impact of CNC on the hydrophobic composite film, particularly focusing on its contribution to film morphology, thermal properties, and mechanical properties, significantly enhancing its hydrophobicity. Experimental results demonstrate that the mold with a rough surface constructs numerous rough and porous structures on the coating film surface, significantly enhancing its hydrophobicity. Notably, the C<sub>28</sub>–CNC/WPU composite film prepared using octacosanol-modified CNC exhibits the best hydrophobicity, with a water contact angle reaching 122.80°. This strategy of preparing hydrophobic coating films through a simple and effective method not only overcomes limitations of waterborne coatings in terms of water resistance and mechanical properties but also holds significant potential for environmentally friendly coatings, offering new insights for waterborne coating development.</p>\u0000 </div>","PeriodicalId":183,"journal":{"name":"Journal of Applied Polymer Science","volume":"142 27","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144244626","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Utilizing 1,2,4,5-tetracyanobenzene (TCNB) as electron acceptor (A), carbazole (CARB) and dibenzothiophene (DBZP) as electron donors (D), two charge transfer complexes (CTCs) exhibiting red and green colors were successfully assembled. Poly(urea-formaldehyde) microcapsules encapsulating either donor or acceptor components were synthesized via in situ polymerization of an oil-in-water emulsion. A systematic investigation was conducted to assess their composition, morphology, thermal stability, and self-reporting ability. The microcapsules incorporated into the poly-(dimethylsiloxane) (PDMS) matrix ruptured upon mechanical failure of the polymer coating. This rupture facilitated the release of donor and acceptor components into the matrix, where they subsequently formed CTCs, resulting in a significant color transformation. To visually indicate crack penetration depth, we developed a multilayered polymer incorporating various types of microcapsules. When subjected to scratches of differing depths on the polymer matrix, different CTCs are activated that allow for visual detection of crack penetration depth based on their fluorescence color. Furthermore, this methodology can be integrated with hexamethylene-diisocyanate (HDI), a self-healing reagent, to develop a smart coating with autonomous self-healing and self-reporting functions. The dual-function coating is achieved by integrating the HDI and CTCs components into one microcapsule in the matrix, without any external intervention.
