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
