摘　　要：通过硬脂酸对ZnO粒子的改性,使其表面引入了疏水性的甲基,将改性后的ZnO粒子与低表面能物质聚二甲基氧烷经过混合陈化固化过程后,在钢片上形成聚二甲基硅氧烷/ZnO超疏水涂层。采用接触角分析仪、扫描电镜、红外光谱,表征涂层表面的形貌和疏水性。结果表明,改性后的ZnO粒子在聚合物上构造微/纳米双重粗糙结构表面,涂层表面具有优异的自清洁性,水的静态接触角达161°,滚动角5°。该方法简单有效有巨大的应用前景。ZnO particles was modified, then its surface was introduced to hydrophobic methyl by the stearic acid, and polydimethylsiloxane/ZnO superhydrophobic was formed on the steel sheet with modified ZnO particles and the low surface energy polydimethylsiloxane by mixing and curing methods. The surface morphology and the superhydrophobicity was characterized by the contact angle measurement, scanning electron microscope and Fourier transform infrared spectrometry characterize. The results showed that modified ZnO particles on the polymer had elaborate micro/nano double roughness structure, and the coating surface exhibited self-cleaning property with a water static contact angle of 161° and sliding angle of 5°. This method had good prospect for applications.
