Abstract Poly(dimethylsiloxane) (PDMS) elastomer coatings containing an amphiphilic hydrolyzable diblock copolymer additive were prepared and their potential as marine antifouling and antiadhesion materials was tested. The block copolymer additive consisted of a PDMS first block and a random poly(trialkylsilyl methacrylate (TRSiMA, R = butyl, isopropyl)-co-poly(ethyleneglycol) methacrylate (PEGMA) copolymer second block. PDMS-b-TRSiMA block copolymer additives without PEGMA units were also used as additives. The amphiphilic character of the coating surface was assessed in water using the captive air bubble technique for measurements of static and dynamic contact angles. The attachment of macro- and microorganisms on the coatings was evaluated by field tests and by performing adhesion tests to the barnacle Amphibalanus amphitrite and the green alga Ulva rigida. All the additive-based PDMS coatings showed better antiadhesion properties to A. amphitrite larvae than to U. rigida spores. Field tests provided meaningful information on the antifouling and fouling release activity of coatings over an immersion period of 23 months.

用于船舶涂料的两亲性可水解聚二甲基硅氧烷-b-聚（甲基丙烯酸乙二醇酯-co-甲基丙烯酸三烷基甲硅烷酯）嵌段共聚物。二、防污实验室测试和现场试验

摘要 制备了含有两亲性可水解二嵌段共聚物添加剂的聚二甲基硅氧烷 (PDMS) 弹性体涂料，并测试了它们作为海洋防污和防粘材料的潜力。嵌段共聚物添加剂由 PDMS 第一嵌段和无规聚（甲基丙烯酸三烷基甲硅烷酯，TRSiMA，R = 丁基，异丙基）-共聚（乙二醇）甲基丙烯酸酯 (PEGMA) 共聚物第二嵌段组成。不含 PDMS-b-TRSiMA 嵌段共聚物添加剂PEGMA 单元也被用作添加剂，涂层表面的两亲特性在水中使用捕获气泡技术来测量静态和动态接触角进行评估。通过现场测试和对藤壶 Amphibalanus amphitrite 和绿藻石莼的附着力测试，评估了涂层上宏观和微生物的附着情况。所有基于添加剂的 PDMS 涂层对 A. amphitrite 幼虫的抗粘附性能均优于对 U.rigida 孢子的抗粘附性能。现场测试提供了有关涂层在 23 个月的浸泡期内的防污和污垢释放活性的有意义的信息。
