使用扫描电镜和接触角测量仪，观测了蝴蝶翅粗糙表面的各向异性，进行了机理分析。结果表明，蝴蝶翅表面微观复合结构(一级结构、二级结构、三级结构)具有显著的各向异性，并由此导致液滴在蝴蝶翅表面的滚动行为及自清洁性呈现各向异性，正向滚动角<垂向滚动角<逆向滚动角。蝴蝶翅表面可作为纳米自清洁表面的仿生制备模板。翅表面的各向异性是蝴蝶长期进化的结果，对于蝴蝶的生存和繁衍具有重要意义。

Using a scanning electron microscopy and a contact angle measuring system, the anisotropic property of rough surface on but-terfly wing was investigated, and the corresponding mechanism was analyzed. According to the results, the complex microstructures of butterfly wing surface ( primary, secondary, and tertiary structures) possess remarkable anisotropic property, which result in anisotropic property of droplet sliding behavior and self-cleaning on butterfly wing surface, forward sliding angle<perpendicular sliding angle<backward sliding angle. Butterfly wing surface may be used as a bio-template for biomimetics fabrication of nano self-cleaning sur-face . The anisotropic property of butterfly wing surface is the outcome of long-term evolution and is of great significance for survival and prosperity.
