抄録

Transparent and homogeneous coating films of the compositions SiO2, 98SiO2⋅2TiO2, 95SiO2⋅5TiO2 and 78.3SiO2⋅1.7TiO2⋅20CuO in mol% were prepared by immersing a sodalime glass substrate into metal alkoxide solutions, pulling it up, drying and heating. Effect of preparation conditions on the properties of films was examined. The time for hydrolysis of the solution, that is, interval between preparation of the solution and its application, and the drying time were varied from 1h to 2d and from 1min to 1h, respectively. The films of 0.1-0.3μm in thickness were transparent and homogeneous when the time for hydrolysis of the solution and drying time were short. The thickness of the films could be increased up to 0.5μm by adding a viscosity-increaseing agent to the solution. Defects such as crack, opaqueness or peeling off were observed when the film was thicker than 0.5μm. Scratch strength of the films was higher than that of the glass substrate and increased with increasing heating temperature and heating time. Adhesive strength of the SiO2 film was higher than 100kg/cm2.
