摘　　要：将N-(羟甲基)丙烯酰胺(NMA)引入丙烯酸自抛光树脂体系制备了具有自交联特性和防污性能的RZn-NMA-X自更新涂层。通过将自抛光树脂与亲水性交联网络相结合,在60 d的静态泡水实验中,RZn-NMA-X涂层在海水中展现出稳定的水解速率和稳定的成膜表面。实验室生物测定和150 d海洋现场测试表明,RZn-NMA-X聚合物具有良好的防污性能,最佳含量为5%NMA。研究表明,适量NMA的引入不仅增强了涂层防污性能,而且较好的表面特性为其逐步抛光,抵抗生物污损提供保障,有利于增加海洋设备服役时长。本工作所提制备方法简单,原料廉价易得,可用于防污应用的规模化生产。A novel self-renewable coating RZn-NMA-X with self-crosslinking properties and antifouling performance was prepared by introducing N-Methylol acrylamide(NMA)into a self-polishing acrylic resin.The coating formed by the combination of a self-polishing resin with a hydrophilic crosslinking network referred to as RZn-NMA-X,exhibited a stable hydrolysis rate and stable film-forming surface in seawater in a 60 d static soaking test.The laboratory bioassay and 150 d marine field test showed that the RZn-NMA-X polymer has good antifouling properties with an optimal content of 5%NMA.In conclusion,the incorporation of an appropriate amount of NMA not only enhances the antifouling performance of the coating,but also provides assurance for its gradual polishing and resistance to biofouling due to its favorable surface characteristics,which is beneficial for enhancing the longevity of marine antifouling in coating applications.The preparation method suggested in this study is straightforward,and the raw materials are affordable and readily available,making it suitable for large-scale production in antifouling applications.
