摘要： 固体表面的润湿性受到表面粗造度和表面微结构的影响。在分析总结几种常用表面微结构加工技术的基础上，提出使用射流掩膜电解加工方法，在不锈钢表面加工微坑阵列结构，研究加工电压对微坑尺寸影响规律和微结构对润湿性的影响。将不锈钢微坑结构作为模具，用聚二甲基硅氧烷（polydimethylsiloxane，PDMS）注塑出微凸结构，用氟硅烷修饰后测量其静态接触角为（151.7±0.51）°。

关键词: 润湿性, 掩膜电解加工, 微结构, 接触角

Abstract: The wettability of the solid surface is affected by surface roughness and surface microstructure. On the basis of analyzing and summarizing several common surface microstructure processing techniques, the jet mask electrolytic processing method is proposed to process the micro-pit array structure on the surface of stainless steel, and study the influence of processing voltage on the size of the micro-pit and influences of the wettability on the microstructure. The stainless steel micro-pit structure is used as a mold, and the micro-convex structure is injection molded by PDMS (polydimethylsiloxane). The static contact angle is measured by fluorosilane and the contact angle is (151.7±0.51)°.

Key words: wettability, mask electrochemical machining, microstructure, contact angle
