The current paper reports a novel model of a marine antibiofouling surface based on polymer brushes on a wrinkled silicone elastomer. Polymer brushes (POEGMA and PSPMA) were grafted via surface-initiated atom transfer radical polymerization (SI-ATRP). Successful grafting was verified with various characterization techniques including infrared spectroscopy, X-ray photoelectron spectroscopy and contact angle measurements. A series of laboratory static and dynamic bioassays as well as field immersion tests were carried out to systematically investigate the relationship between surface chemistry, surface topography and antifouling properties. The results indicated that the adhesion of marine organisms was strongly influenced by the surface chemistry composition and surface topography structure. The synergistic effect of the surface chemistry, surface topography and bulk properties of the substrates endowed the new marine coatings with excellent antifouling properties.
本文报道了一种基于聚合物刷修饰褶皱硅橡胶的新型海洋抗菌表面模型。聚合物刷（POEGMA 和 PSPMA）通过表面引发原子转移自由基聚合（SI-ATRP）接枝到表面。通过各种表征技术，包括红外光谱、X 射线光电子能谱和接触角测量，验证了接枝的成功。进行了一系列实验室静态和动态生物测定以及现场浸泡试验，以系统研究表面化学、表面形貌和抗污性能之间的关系。结果表明，海洋生物的附着强烈受到表面化学组成和表面形貌结构的影响。表面化学、表面形貌和基底的体性质的协同效应赋予了新型海洋涂层优异的抗污性能。
