Abstract
This research involves studying the effect of catalyst and heat treatment temperature on the coating properties of sol-gel titanium dioxide TiO2 thin films. There are several studies discussed about the effect of catalyst and the influence of heat treatment temperature on the TiO2 coating properties. Nonetheless, there is no systematic research on this title. In the sol-gel production route, titanium tetraisopropoxide (TTIP) is used as a precursor to produce TiO2 thin film. Hydrochloric acid (HCl) act as acidic catalyst and ammonium hydroxide (NH4OH ) act as alkaline catalyst are manipulated to investigate the influence of various catalyst-type on the microstructure and morphological properties of TiO2 thin films. The TiO2 thin films will then deposit on glass substrate by adapting dip-coating technique. Then, the thin film samples are heat treated at different temperatures, particularly 500℃ and 700℃ to analyze the effect of annealing temperature on the morphology and phase transformation of TiO2 thin films through different catalyst. It was found that TiO2 thin film exhibits different surface morphology when different catalysts were used (distinct pH). When there is use of alkaline catalyst, the film exhibits particle shape instead of sheet-form. In addition, it was also observed that the distribution of TiO2 particles behaved differently when different annealing temperatures were applied on the films. It was found that the agglomeration is more dispersed at higher temperature.
