Abstract

The TiO2-SiO2 optical films prepared from a sol-gel precursor were deposited on enamel surface using dip-coating techniques. The films were calcined different time from one hour till ten hours to investigate effect of calcination on self-cleaning and structural properties. Effects of film crystal structure, microstructure, photocatalytic activity and optical properties of the films were investigated using XRD, AFM and spectrophotometer and contact angle measurement. The TiO2-SiO2 dip-coating optical films calcined 1 h resulted in high structured surfaces, which were found to increase the photocatalytic activity.
