摘　　要：本文从仿生学的思路出发,分别采用化学腐蚀和阳极氧化的手段在金属表面构建出类荷叶表面的结构,并用低表面能物质(氟硅烷)对其进行修饰成膜,制备出高性能的微/纳米双尺度细观结构不粘薄膜。该薄膜最佳疏水接触角度达到163.0°,疏丁羟胶的角度也达到136.0°。The water contact angles of lotus surfaces can be up to 150° which is defined as superhydrophobicity. According to the bionics, the anti-sticky thin film coated on metal board with high performance miero/nano-struetures was prepared in this way, using strong acid corrode the metal or using anodie oxidation to process surface to form miero/nano-struetures and then decorate it with solutions of FAS which is employed as lyophobie agent. The water-contact angles of the prepared thin films can be up to 163.0° and the. angles of HTPB can also be up to 136°.
