Abstract

This research using sol gel technique of titanium dioxide thin films for self-cleaning glass production. Self-cleaning glasses were produced by dipping 5 mm thick float glasses in the titanium dioxide solution which prepared from titanium tetraisopropoxide in isopropanol under pH 2-3. The surface morphology of thin films at different withdrawal speed (3, 9, 14 cm/min), number of layers (1, 3, 5 layers) and annealing temperature (350, 450, 550ºC) were studied with scanning electron microscope (SEM) and x-ray diffraction (XRD). The optical transmittance and photocatalytic activity were carried out by UV-visible spectroscopy. Superhydrophilicity was investigated using contact angle analyzer. The results indicate titanium dioxide thin films deposited at withdrawal speed of 3 cm/min and annealed at 450ºC for 5 layers were very smooth uniform surface cover on glass with good adhesion and highest anatase phase. Transparency of the self-cleaning glass was similar to that of the uncoated glass. The photocatalytic activity of self-cleaning glass was examined with methylene blue degradation test. After 300 minute irradiation, degradation efficiency was 94.83%. After 24 hour UV illumination, the water contact angle drops were 0 degree, and the self-cleaning glass showed superhydrophilic. Chemicals cost of self-cleaning glass production were 40.87 bath/m2.
