摘　　要：通过全氟辛酸(CF3(CF2)6COOH)乙醇溶液一步浸泡法制备了具有微纳米复合结构的超疏水锌片,考察了反应温度、反应时间等对表面疏水性的影响.分别用SEM、XPS和FT-IR等技术对材料的表面形貌和化学成分进行表征,同时用Cassie理论对表面的润湿性进行分析.结果表明,所制备的超疏水表面对常见溶剂和食盐水都具有良好的耐受性.Superhydrophobic film on the zinc surface with micro-nanometric composite structure is successfully prepared by a simple immersion process of pentadecfluorooctanoic acid solution in ethanol,and the influences of the temperature and the reaction time on surface wettability are studied.The surface morphology and chemical composition of the superhydrophobic films are characterized by SEM,XPS and FT-IR spectra,respectively.In addition,the surface wettability is explained and analyzed using Cassie theory.The prepared superhydrophobic surface shows perfect environmental stability and durability for some solvents and NaCl solution.
