Fabrication of non-wettable film by controlling the surface morphology of silica by sol-gel method |
| 초록 |
Solar cells or high-performance organic electronic devices exposed to extreme external environments are required to have high barrier properties. Films made by combining particles containing fluorine components can realize a non-wetting device for water. TEOS was used as precursors and silica surface was synthesized by adding 1H, 1H, 2H, 2H, 2H-perfluorooctyltriethoxysilane which was a fluorosilane to lower the surface energy to form mopolroge. By the molecular weight using a larger alkoxy group as solvent changing the ratio to adjust the particle size. Dispersing the obtained particles of the polysilazane was produced in a film of excellent properties by improving the hardness and optical transmission properties. As a result of measuring the water contact angle of the film in which the fluorine particles were dispersed, the superhydrophobic surface having a contact angle characteristic of 150 degrees or more was confirmed. |
