To investigate the photo-induced hydrophilicity of TiO₂ films and its durability, a series of TiO₂ films containing polyethylene glycol (PEG) 2000 with different contents are prepared. The photo-induced hydrophilicity of the films is investigated by recording the water-droplet contact angle on the films? surface under UV irradiation, and the hydrophilicity durability is monitored under dark storage conditions. The photo-induced hydrophilicity of TiO₂ films and its hydrophilicity durability are enhanced by introducing 2.0% (w) of PEG into the TiO₂ sol. From Fourier transform infrared (FTIR) spectra and ultraviolet-visible diffuse reflection spectra (UV-Vis DRS), we infer that PEG acts as an electron donor to scavenge the photogenerated holes in TiO₂ and promotes the formation of Ti³⁺ sites, which are induced by the Ti⁴⁺ sites accepting the photo-generated electrons of TiO₂. This promotes the formation of hydrophilic sites (the surface hydroxyl species). Compared with the pure TiO₂ film, the Ti³⁺ sites in the TiO₂/PEG films are more stable, which prolongs the hydrophilicity of TiO₂ films under dark conditions. This study is significant for the application of TiO₂ as a self-cleaning material, and is also a facile approach to investigate the transient behaviors of TiO₂ under UV irradiation.
