Preparation and Characterization of TiO2 Film on Glass Flake

Article Preview

Abstract:

A TiO2 film was prepared on glass flake with Ti(OBu)4 as a main material by peptization and reflux method at 80°C in acidic abundant aqueous solution. The surface topography and surface phase structure were characterized by scanning electron microscope, energy spectrum, X-ray diffractometer, X-ray photoelectron spectroscope, and the bonding strength between film and glass flake was researched by ultrasonic vibration. The results indicated that the TiO2 film, the main phase was anatase and a little rutile, coated on the glass flake uniformly. Along with growth of TiO2 on surface of glass flake, the formation maybe base on two different mechanics, at the earlier stage, TiO2 coupled surface of glass flake with Si-O-Ti chemical bond, but with physical deposition at final.
