基于仿生的非光滑表面防污减阻技术发展现状分析

基于船舶防污减阻的必要性,从仿生角度出发,介绍了仿生表面防污减阻这种新型环境友好型防污方法。重点分析了鲨鱼、海豚、贝壳和甲鱼壳等仿生原型的表面微结构,探索了这些生物表面微结构的防污减阻机理。基于生物表面微结构的防污减阻效应,阐述了现有的水生生物非光滑表面防污减阻技术,最后对仿生表面防污减阻方法进行了展望。

Analysis of present development on technologies of antifouling and drag reduction based on bionic non-smooth surfaces

The antifouling and drag reduction on ship surface are known to be necessary. In this article a novel environmental friendly method inspired by biology is introduced. The micro structure on the surface of shark, dolphin, shell and turtle is described in detail. In addition, the mechanism of micro structure which has the ability of antifouling and drag reduction is analyzed. The antifouling and drag reduction theories of nonsmooth surface extended from the skin of aquatic creature are introduced. It is expected that the application of micro structure surface will alter the transportation in some way beneficial to the goals of increased drag reduction.
