| Summary: | 碩士 === 義守大學 === 材料科學與工程學系 === 101 === Water repellency of a solid surface is one of the most challenging subjects for both fundamental research and practical application. A surface with water contact angle in excess of 150° and sliding angle less than 10° is defined as superhydrophobic. The superhydrophobic surfaces with anisotropic wettability have received significant attention for their potential applications in biochips, cell motility studies, directional water-collecting, and microfluidic devices. In this paper, we prepared several superhydrophobic films from carbon nanotube (CNT)/polybenzoxazine coatings. A designed path line is then created on the prepared superhydrophobic surface. We achieved anisotropic wettability on the patterned superhydrophobic surface. The sliding of a ball-like water droplet traces the designed line on the patterned superhydrophobic surface. Interestingly, we have found that the patterned superhydrophobic surface exhibits good adhesion of water droplets, which can be served as a “mechanical hand” to transfer water droplets from a superhydrophobic surface to other surface.
