Preparation of SiO2 Film by Sol-Gel


Article Preview

In recent years, the hydrophobic and self-cleaning surface has aroused extensive attention due to its special nature such as waterproof, pollution prevention, antioxidant nature, and so on. In this paper, sol-gel was used to prepare the hydrophobic coating on ceramic surface. Ethanol and TEOS were mixed to prepare the sol as 1:1 volume ratio, and the sol would be coated on the ceramic surface treated by some ways. Then the samples were dried in a certain temperature, then calcined. At last the samples were modified with a certain percentage modifier. In this article, three different factors were discussed, such as vacuuming times, modifing time, and calcining temperatures, eventually it is gotten that the optimal experimental conditions are using 20min to vacuum, 1h to modify and 550 to calcine.
