Among the key factors that affect the formation of metal oxides, which consequently influence the performance of thin film prepared via sol-gel method, are: pH of the reaction solution, hydrolysis ratio, type of solvent and reaction temperature.
Materials and Methods For the preparation of TiO2 coating, titanium (IV) isopropoxide (TTiP) (Sigma Aldrich Co.), ethanol, hydrochloric acid (HCl) and deionized water were used as titanium precursor, solvent, catalyst and hydrolysis medium respectively.
