In the present research, automotive windshield samples were successfully coated with SiO2-TiO2 nanostructure layer using the sol-gel technique for self- Cleaning and photocatalytic applications. This procedure resulted in transparent, crack-free, self-cleaning, nanostructure SiO2-TiO2 films. To prevent the thermal diffusion of the sodium ions from the glass substrate to TiO2 layer, the SiO2 layer was pre-coated on the glass by the sol-gel method. The coated samples were dried for 48 hour at room temperature to allow slow solvent evaporation and condensation reactions due to rapid sol-gel reaction of titania precursor. Then, the samples were annealed at 100℃ for 30 min and at the final temperature (500℃ and 700℃) for 30 min immediately. The crystalline structure, surface morphology, photocatalytic activity and hydrophilic properties of the films were investigated using XRD, SEM, FE-SEM, UV-Vis spectrophotometer and contact angle measurement, respec- tively. The FE-SEM surface morphology results indicate that the particle size increases from 19 to 42 nm by increasing the annealing temperature from 500℃ to 700℃. Likewise, XRD illustrate the crystal anatase and rutile as main phases for SiO2-TiO2 films annealed at 500℃ and 700℃, respectively. Increasing heat treatment temperature from 500 to 700℃, de- creases the photocatalytic activity and inversely increases of the contact angle of the films.
