Deposition Conditions

ABSTRACTBackscattering spectrometry has been used to determine the density of TiO2 sol-gel films. The density of the as-deposited films relative to that of anatase varies slightly with respect to deposition conditions and is approximately 0.5. Annealing at temperatures as high as 750°C increases the relative density to 0.7 with concomitant decreases in the O:Ti ratio and H content but it does not result in complete densification. Film densities are consistently higher for films annealed under dynamic vacuum compared to those in air.

Transparent nano- coating was prepared by Sol-Gel method from titanium dioxide TiO2 which has the ability to self-cleaning coating used for hospitals, laboratories, and places requiring permanent sterilization. Three primary colors are selected (red, blue, and yellow) as preliminary study to the effect of these colors on the nano-coating. Three traditional oil paints color were used as base, then coated by a layer of TiO2-Sol and deposited on the paints. The optical properties of TiO2-Sol were measured; the maximum absorption wavelength at (λmax=387 nm), the refractive index (n=1.4423) and the energy band gap (Eg=3.2 eV). The structure properties found by X-ray diffraction of TiO2-Sol illustrated that TiO2-Sol is polycrystalline nanoparticle have anatase phase also the morphological properties measured by Scanning Electron Microscopy (SEM) obetained the average grain size of TiO2-Sol was (50.427 nm). Self-cleaning properties measured by tensiometer dives. The best color gave the highest response to self-cleaning is the yellow color where the contact angle before exposure to UV ( = 101.47º ,at t = 0 min) and after exposure over time ( = 1.75º ,at t = 50 min), thus the water sheet of the surface and remove all contaminants.

Dip Coating Technique

The pure TiO2and SnO2-TiO2thin films on glass substrate were fabricated using a sol-gel dip coating technique. The thin films were annealed at the temperature of 700 °C for 2 h with the heating rate of 10 °C/min. The microstructures of the fabricated thin films were characterized by SEM and XRD techniques. The photocatalytic activities of the thin films were also tested by the degradation of methylene blue (MB) solution under UV irradiation. Finally, hydrophilic or self-cleaning properties of thin films were evaluated by measuring the contact angle of water droplet on the thin films with and without UV irradiation. It was found that 1 %mol SnO2-TiO2thin films shows the highest of photocatalytic activity and provide the most self-cleaning properties.
