Abstract Biofouling has been a great challenge for the exploitation of marine resources and could be generally avoided by decorating with protective coatings on the ships or equipment, while the process will produce a great amount of volatile organic compounds (VOC) and lead to or even aggravate environmental hazards. A high-performance water borne antifouling coating (WBAC) composed of self-polishing emulsion and bioactive ingredient was prepared, in which triisopropylsilyl ester acted as the self-polishing matrix and zwitterionic complex with cupric ion was used as the main antifoulant. The surface wettability, self-polishing rate, essential mechanical properties and the broad-spectrum antifouling capability were characterized in the lab. The experimental results indicated that the designed fully solvent free coating was capable of adjustable polishing rate and possessed robust stability and excellent antifouling performance for the settlement of green algae, red algae and diatom. Moreover, the long-term but robust performance of the engineered WBACs has been proved in the marine field test. Considering its solvent-free character and excellent antifouling behavior, this research would provide insights into the design of the next-generation of the eco-friendly and sustainable marine antifouling coating.

自抛光乳液平台：面向水性海洋防污涂料的环保表面工程

摘要 生物污垢是海洋资源开发面临的巨大挑战，一般可以通过在船舶或设备上涂装防护涂料来避免，但在此过程中会产生大量的挥发性有机化合物（VOC），导致甚至加重环境危害。以三异丙基甲硅烷基酯为自抛光基体，以铜离子的两性离子络合物为主要防污剂，制备了一种由自抛光乳液和生物活性成分组成的高性能水性防污涂料(WBAC)。在实验室中表征了表面润湿性、自抛光率、基本机械性能和广谱防污能力。实验结果表明，所设计的全无溶剂涂层抛光速率可调，对绿藻、红藻和硅藻的沉降具有较强的稳定性和优异的防污性能。此外，工程 WBAC 的长期但稳健的性能已在海洋现场测试中得到证明。考虑到其无溶剂特性和优异的防污性能，这项研究将为下一代环保和可持续海洋防污涂料的设计提供见解。
