边界结构是显著影响微藻定居的重要因素。为了研究界面结构对仿生织构涂层防污性能的影响，采用仿生复制方法制备了3种不同的界面结构，并通过记录微小尼茨藻、三角褐指藻和小球藻等污损微藻的沉降量对其进行了评价。结果表明，叠瓦状边界结构对阻垢效果较好，而凹陷边界结构和凸起边界结构对阻垢效果较差。特别是，凹陷的边界结构表现出最差的防污性能，这归因于为微藻提供了庇护所。深入揭示了微藻附着在不同边界结构仿生织构涂层上的防污机理。
Boundary structure is an important factor for significantly influencing the settlement of microalgae. In order to investigate the effect of boundary structure on the antifouling performances of biomimetic textured coatings, three different boundary structures were fabricated via biomimetic replication method and evaluated by recording the settlement amount of fouling microalgae includingNitzschia closterium f. minutissima,Phaeodactylum tricornutumandChlorella. The results showed that imbricate boundary structure was more positive for antifouling, but depressed boundary structure and raised boundary structure played a negative role for antifouling. Especially, the depressed boundary structure displayed the worst antifouling performance which attributed to providing shelters for microalgae. The antifouling mechanism of microalgae settled on the biomimetic textured coatings with different boundary structures was revealed deeply.
