Abstract
A novel titania sol for the preparation of hydrophilic TiO2 films was synthesized
from TiCl4. TiO2 films were prepared by spraying the sol on glass substrates and
the hydrophilic properties of the films were investigated with illumination of UV
light. The contact angle of a water drop on the films decreased to less than 7°,
which indicates the excellent hydrophilicity of the TiO2 films.
