Preparation and Performance Research on Antifouling Coating with Large-size Bionic Microstructure

  • 摘要: 鲨鱼、海豚等海洋生物的表皮结构具有防污功能,猪笼草的口缘区具有液膜单向传递特征,这些表面结构形貌可为船舶涂层的防污和减阻设计提供重要依据。根据鲨鱼皮表面肋条状结构、猪笼草口缘区单向沟槽和弧形结构,设计简化单向V型沟槽微结构形貌,并结合CFD模拟计算分析V型沟槽减阻性能,确定了仿生微结构的形貌及尺寸。利用皮秒激光刻蚀技术,在铝合金基材表面刻蚀微结构形貌模板,然后在未完全固化的防污涂层表面压印,通过对软/硬模板、固化时间、压印压强等工艺条件参数的考察及优化,制备出较大尺寸的仿生微结构表面涂层。使用三维形貌测试仪、接触角测试仪等表征仿生微结构涂层表面,并进行多海域实海浸泡性能实验。结果显示,该仿生涂层表面微沟槽间距为90.8 μm,深度为60.3 μm,其表面接触角为121.7°,微结构形貌均匀,具有良好的实海防污性能。
