| 제목 | Bionic Superhydrophobic Surface with Nanoparticle-Stabilized Triblock Copolymer Micelles |
| 초록 | Herein we describe the fabrication of a bionic superhydrophobic surface by castting the poly(t-butyl acrylate)-b-poly(dimethylsiloxane)-b-poly(t-butyl acrylate) triblock copolymer micelle solution. This micelle solution was stabilized by adding a small amount of nanosilica particles (size=11nm), which inhibit the severe aggregation of micelles during film formation process. Micro-nanoscale binary structured (MNBS) surface could be made by the casting and drying of block copolymer micelle/nanosilica solution at room temperature. The micelles were surrounded with nanosilica particles, and the top surface of coating is covered with nanosilica particles having hydroxyl groups. Therefore, two kinds of fluorination of the MNBS surface for the superhydrophobicity; one is the chemical vapor deposition (CVD) of perfluorosilane, another is the dipping in hexane/perfluorosilane solution, resulting in successful formation of a multilevel-structured superhydrophobic surface. 그림1.
