摘要 通过置换反应,在锌基底上制得银纳米涂层,经十二烷基硫醇(DDT)、十八烷基硫醇(ODT)表面修饰后表现出较好的超疏水性和抗腐蚀性,接触角达到151.8°和156.2°,滚动角接近5°.涂层表面的超疏水性受反应时间、AgNO3浓度及化学表面能的控制.本文对银纳米涂层超疏水效应的形成及其抗腐蚀性进行了分析、探讨. Silver nano coatings were fabricated on zinc substrate by a facile method of replacement reaction. The coatings enhibit properties of superhydrophobicity and anticorrosion after being modified by dodecanethiol （DDT） and octadecanethiol （ODT）. Contact angles on modified coating are 156.2° and 151.8°, respectively, and the glide angle is approximately 5°. Silver coatings＇ superhydrophobicity is dominated by reaction time, concentration of AgNO3 and surface free energy. Finally, superhydrophobic and anticorrosion mechanisms of the coatings were analyzed and discussed.
