Cutin, a natural polyester found in plant cuticle, offers promising properties such as hydrophobicity and low gas permeability, making it an appealing component to formulate paper coatings. In this study, poly(ester-urethane) (PU) coatings derived from cutin extracted from tomato peels were investigated as sustainable barrier layers. The synthesis was accomplished in two steps: cutin monomers obtained by a hydrolytic extraction were at first esterified with 1,4-butanediol and then polymerized by addition with isophorone diisocyanate. Importantly, the reaction parameters, particularly the reaction time in the first esterification step, were systematically optimized to obtain three formulations (PU30, PU38, PU50) with distinct esterification degrees (30, 38, and 50 %, respectively). The thermal stability by TGA analysis of the resulting PUx was little affected by the preparation procedure, while the glass transition temperature (Tg) was found to decrease of several degrees when the esterification degree increased. All the three formulations could be applied onto two different paper substrates: a standard paper for printing (Pp) and a single face coated paper (Gp) for packaging application. SEM analysis showed superior coverage and adhesion on Gp, and barrier tests confirmed improved resistance to water and grease, especially with PU30. Biodegradability and recyclability assessments demonstrated that PU30 maintained a favorable balance between functional performance and environmental compatibility, in contrast to PU38 and PU50, which significantly hindered these properties. Overall, the results highlight the potential of PU30 coatings as a viable, bio-based solution for enhancing paper packaging sustainability.</div></div>","PeriodicalId":20834,"journal":{"name":"Progress in Organic Coatings","volume":"213 ","pages":"Article 109946"},"PeriodicalIF":7.3,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145927833","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 superhydrophobic titanium dioxide–fluorinated graphene (TiO<sub>2</sub>@FG, abbreviated as TFG) composite coating was fabricated via a simple one-step spraying technique. Leveraging the strong particle-adsorption capability of the FG surface, the issue of metal nanoparticle aggregation within the coating was effectively addressed. The resulting TFG coating possesses ultra-low surface energy and a stable micro-nano hierarchical architecture, which synergistically confer long-term antifouling efficacy. Quantitative assessments revealed a 77.9% reduction in protein adsorption after 12 h and sustained bacterial adhesion resistance below 20% even after 120 h on the TFG surface, compared to unmodified stainless steel. Furthermore, the coating exhibited exceptional mechanical robustness, retaining a water contact angle above 150° and an adhesion force under 30 μN after repeated abrasion. Under a friction test at 12 MPa for 30 min, the low friction coefficient stabilized at 0.08.
