| Popis: | 96 The two main methods to prepare nano scale TiO2 photocatalysis coating liquid are chemical and physical methods. The different methods have its advantage and demerit. Our experiment uses Sol-Gel method and the TiCl4 forerunner to manufacture TiO2 coating liquid. The method of our experiment is cheap and simple. We use spin coating to manufacture nano scale TiO2 photocatalysis thin film. We use XRD (X-Ray Powder Diffractometer) instrument to do crystal analysis. Field Emission Scanning Electron Microscope (FESEM) analyzes the grain size. After the nature of TiO2 thin film is determinated, we continue to do contact angle experiment and the defogging experiment. The results of our experiment conform to theory. In contrast to other literatures, we add defogging experiment. We confirm that super-hydrophilic ensure perfect effect of defogging. |
