TiO2 films on Al alloy (Al), anodic aluminumoxide (AAO/Al, formed at the surface of Al alloy), indium-tin oxide glass (ITO/glass) and glass were prepared by a dip coating method. The measurement of water drop contact angle under UV irradiation shows that TiO2 films on the conducting Al substrate have a higher activity for photoinduced hydrophilicity than that on the non-conducting AAO/Al substrate. Alternatively, TiO2 films on the conducting ITO/glass substrate have a lower activity for photoinduced hydrophilicity compared to TiO2 films on the non-conducting substrate glass. These observations are due to electron transfer between TiO2 and substrates. Al acts as an electron donor and donates electrons to TiO2, which results in an increase in the photoinduced hydrophilicity of TiO2 film. ITO accepts the photogenerated electrons, which results in a decrease in the photoinduced hydrophilicity of TiO2 films.
