Photocatalytic hydrophilic treatment of polyester surfaces is investigated using TiO2 as a
photocatalyst. The hydrophilicity of photocatalyzed polyester film and fabric is evaluated by
means of water absorbency, contact angles, and XPS analyses. Irradiation of uv light with an
approximate wavelength of 352 nm produces effective photocatalytic action of TiO2 on
polyester. The surface properties of photocatalyzed polyester materials significantly improve
and show high hydrophilicity. XPS analysis also indicates that the photocatalytic reaction of
TiO2 generates C—O and C==O groups on the surface of polyester.
