MANUFACTURING METHOD OF SUPER HYDROPHILIC TITANIUM OXIDE THIN FILM AND TITANIUM OXIDE THIN FILM MANUFACTURED BY THE METHOD

摘要

PURPOSE: A manufacturing method of super hydrophilic titanium oxide thin film and a titanium oxide thin film which is manufactured by using thereof are provided to improve light transparency and to have super hydrophilicity by using sol-gel process. CONSTITUTION: A manufacturing method of super hydrophilic titanium oxide thin film comprises the following steps: mixing titanium tetraisoproxide, isopropyl alcoho, acid catalyst, and ethyl alcohol in order to form sol; coating the sol on the substrate in order to form TiO2 thin film; making the sol to gel by drying the substrate on which the sol is coated; and forming a TiO2 thin film by heat treating the gelled outcome at 400-650 deg. Celsius. A molar ratio of titanium tetraisoproxide, isopropyl alcoho, acid catalyst, and ethyl alcohol is 1:10-30:2-10:0.2-3.
