Most BPA alternatives enhance the toughness of the epoxy cured film but compromise the coating's properties to varying degrees. Therefore, developing a BPA alternative that toughens epoxy resins without sacrificing modulus and mechanical strength remains a significant challenge. In this study, we synthesized dicarboxylic acid compound (PNP) with a structure similar to BPA, using phthalic anhydride and neopentyl glycol. This compound serves as a substitute for BPA. We systematically explored the influence of different PNP contents on the performance of waterborne epoxy resins and coatings. The results showed that PNP is more conducive to preparing waterborne epoxy resins with smaller particle sizes and stable heat storage. Compared with BPA-modified epoxy resin, PNP significantly increases the elongation at break and tensile strength of the cured film. Moreover, different PNP contents can significantly improve the coating's impact resistance, pull-off adhesion, water resistance, salt spray resistance, and acid resistance without affecting other mechanical properties and alkali resistance. This study provides a new perspective for preparing environmentally friendly, high-performance, tough, and stable waterborne epoxy coatings.</div></div>","PeriodicalId":20834,"journal":{"name":"Progress in Organic Coatings","volume":"208 ","pages":"Article 109525"},"PeriodicalIF":6.5,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144662859","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}

While superhydrophobic surfaces offer excellent water repellency and reduced ice adhesion, their limited durability in cold conditions restricts practical use. To address this, photothermal superhydrophobic surfaces have been developed, but achieving high photothermal efficiency, exceptional anti-icing performance, and durability remains a challenge. 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). The resulting surface demonstrated (i) excellent water repellency, with a water contact angle of 161° and a rolling angle of 5°, (ii) outstanding photothermal performance, achieving a 72.3 °C temperature increase under 1 sun illumination for 300 s, and (iii) superior mechanical stability and long-term durability. The SPAI coating demonstrated excellent anti-icing, deicing, and defrosting performance at −25 °C, with a freezing delay of 492 s and deicing/defrosting times of 130 and 141 s, respectively, under 1 sun exposure. It exhibited low ice adhesion strength (45 ± 10 kPa at −20 °C) and maintained durability, with ice adhesion remaining ~99 kPa after 13 icing/deicing cycles. Durability was validated through abrasion, cross-cut tape adhesion, and freeze-thaw tests. The surface also exhibited non-wetting properties when exposed to various food liquids and demonstrated excellent long-term stability in ambient conditions. The proposed surface offers a scalable, durable solution for anti-icing and deicing.</div></div>","PeriodicalId":20834,"journal":{"name":"Progress in Organic Coatings","volume":"208 ","pages":"Article 109523"},"PeriodicalIF":6.5,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144654597","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}

Adding water and oil repellents can enhance paper's barrier properties, but traditional fluorine-containing coatings pose health risks like biotoxicity, accumulation, and migration, leading to global regulatory restrictions. Thus, developing green, biodegradable, bio-based water and oil repellent coatings is the future trend. In this study, taking advantage of the high reactivity of cyanuric chloride (TCT), a chitosan-derived coating (CHI-g-OA₂) with a double hydrophobic chain structure was successfully constructed. The formula for the preparation was optimized by the response surface method. This “molecular modification” strategy, which grafts hydrophobic oleyl alcohol chains onto chitosan molecular chains to successfully construct a hydrophobic barrier, effectively solves the problem where competitive hydrogen bonding disrupts the dense hydrogen bond network formed within and between chitosan molecules, leading to significant attenuation of barrier performance. It also achieves the synergistic improvement of the material's waterproof and oil-repellent properties while retaining the original oil and gas barrier function, which meets the standard for food packaging materials.

In this work, silanol terminated polydimethyl silicone fluid (PDMS) was introduced to modify the performance of CSO-WAR to fill the defects of CSO-WAR and achieve the purpose of expanding its application.
