In the case of SiO₂ coated glass, even if the surface of SiO₂ coated glass is hydrophilic at first, the surface becomes hydrophobic due to the deposition of hydrocarbons in the atmosphere. In contrast, SiO₂ thin films deposited by the combination coating method developed in this laboratory have been found to have stable hydrophilicity over a long period of time. By utilizing this method to TiO₂ thin film, it is considered that the hydrophilicity of TiO₂ thin film, which is known as a hydrophilic film, can be improved. In this report, we evaluate the hydrophilicity of TiO₂ thin films deposited by the combination coating method.
