中文摘要: 为减少生物污损给海洋装备带来的危害,开展长效、环保防污技术研究势在必行。单一功能涂层很难应对复杂海洋生物环境,开展不同机制协同防污涂层与技术研究尤为重要。 本项目将界面滑移与无毒接触杀菌机制相结合,利用环保型接触杀菌剂强于杀灭微生物,以及滑移界面高剪切特性善于释放大型生物各自优势,实现两种机制协同作用、互补增强。通过界面滑移机制分子动力学理论模拟,提出污损界面滑移理论模型和高界面滑移最佳条件;基于模拟结果,在接触杀菌组分的聚氨酯基础上设计和制备高滑移表面的双功能材料;通过不同组分涂层防污性能表征和对比,掌握双机制耦合参数、涂层最优化设计与制备方法,揭示协同防污机理。 本研究将为复合涂层机制协同的深入研究及工程应用提供理论依据及技术指导,突破环保型防污涂层技术应用瓶颈。

英文摘要: Building powerful nation of the ocean has been promoted to national development strategies. Biofouling has taken disastrous consequences to marine materials and facilities, so related research about the mechanisms of biofouling and environmentally friendly anti-fouling technology are necessity and importance. Organic coating is economical, simple, and effective for anti-fouling, but the requirements about long-lasting and environmentally friendly restrict its development. Single functional coatings are difficult to cope with the complexity of the marine biological environment, while studying the synergy mechanism of different types of anti-fouling technology is particularly important to perfect new techniques. With the target of developing a long-lasting, environmentally friendly anti-fouling coating, this research propose a novel anti-fouling coating idea. According to molecular modification and assembly, molecular dynamics simulation, microbial experiments and characterization,we attempt to make the environmentally friendly interfacial slip surface coating and nontoxic contact-killing coating complementary. And the contents include slip mechanism between the solid surface and fluid interface, optimization preparation process of high shearing-surface, preparation of dual mechanism coating, activity and stabili
