摘　　要：通过模仿荷叶表面微观结构和表面化学成分的方法,以玻璃为基底在溶液中生长ZnO纳米棒并经表面低自由能化修饰,从而成功制备了ZnO纳米棒阵列超疏水表面.经接触角测量仪表征,该超疏水表面静态水接触角为156°,扫描电镜分析表明所制备的ZnO纳米棒均具有100 nm左右的直径,这种微纳米的复合结构是赋予材料表面超疏水性能的主要因素.最后采用Cassie模型对该超疏水表面的超疏水性能进行了理论分析.A superhydrophobic surface was successfully prepared on glass substrate by mimicking the micro- structure of the lotus and was fabricated of ZnO nanorod array followed by surface fluorination. The contact angle meter showed the surface had a water contact angle of 156 °. Scanning electron microscopy （SEM） demonstrated that all of the nanorods had a uniform diameter of about 100 nm and the structures at the micro and nanometer scale bestowed the prerequisite roughness on the surfaces. The Cassie model was applied to an analysis of the theoretical superhydrophobicity.
