| dc.description.abstract | 奈米級TiO2光觸媒鍍膜液製備，主要分為物理法及化學方法2大類，各有其優缺點(詳見2-4)。本實驗室採用「溶膠凝膠法(Sol-Gel method)」，前驅物為金屬鹽類「四氯化鈦(TiCl4)」，製作出奈米級TiO2光觸媒鍍膜液，主要原因是成本較低且製備簡單。奈米級TiO2光觸媒鍍膜液製備完成後，使用旋轉塗佈儀製備奈米級TiO2光觸媒薄膜。
晶相分析採用X光粉末繞射儀X-Ray Powder Diffractometer(XRD)。粒徑大小採用場發射式掃描電子顯微鏡Field Emission Scanning Electron Microscope (FESEM)。
奈米級TiO2光觸媒薄膜的基本性質確定後，接續做了接觸角實驗、除霧實驗，所得的實驗結果也與理論相當符合。
相較於其他文獻，此實驗除了做接觸角實驗之外，特別加入了自行設計的除霧實驗，以直接的實驗方法證實「具有超親水性，確實具有良好的除霧效果」。 | zh_TW |
| dc.description.abstract | 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. | en_US |
