In this paper, we verified the influence of surface energy according to the gradually changed surface roughness through the implementation of hierarchical micro-nano structure texturing. In generally, it well known that surface roughness has a very important parameter for define the surface characteristics such as hydrophobic or superhydrophobic state and these surface conditions have defined as theoretical models of Cassie-Baxter or Wenzel. In order to fabrication of hierarchical micro-nano structures, we have performed silicon anisotropic wet ... 전체 초록 보기
