- Abstract
- Recently there is an increasing demand for the application of hydrophobic surface in industrial and biological processes. It has been found that the contact angle with liquid, closely related to hydrophobicity of a solid surface, is largely determined by micro/nano-geometrical structure and chemistry of the solid surface. In this research, we studied the change of contact angle on stainless steel surface after the formation of micro patterns by using photolithography, electro chemical fabrication (ECF) and FeCl3 wet etching process. Based on the models built by Wenzel and Cassie- Baxter, the depth of etch, (h), width of pattern (a), space of pattern, (b) were optimized to obtain the largest contact angle. As a result the contact angle was increased by the increase of ratio value. And it was observed that the contact angle was increased by the increase of the surface roughness by using FeCl3 wet etching. It is expected that the hydrophobicity of the stainless steel surface can be controlled by using these methods.
