In this study, we discuss how to improve surface hydrophilicity of TiO2 film. A synthesized nanocrystalline anatase TiO2 by microwave-hydrothermal method was applied. The main advantages of microwave-hydrothermal processing of TiO2 are (a) rapid heating to temperature and (b) extremely rapid kinetics of crystallization. The deposition of the anti-fogging film was performed with a dip-coating method, where the substrate was dipped in a solution of titanium dioxide. This study was to obtain TiO2 thin films by dip-coating in TiO2 aqueous. Films have been deposited on a glass substrates and were found to be homogeneous, and about 100-nm. The obtained thin films were characterized by X-ray diffraction, contacting angle, scanning electron microscopy, UV/VIS spectophotometer, and HAZE computer.
