Fe3+-doped TiO2 films with the pattern surface were fabricated onto glass substrates by a facial photosensitive sol-gel method. The patterned TiO2 film has anatase crystallites and a micro-and nanometer-scale hill-to-valley hierarchical surface structure. The hydrophilicities of all TiO2 films stored in the dark for a long time were evaluated by measuring the water contact angle (CA) without being illuminated by ultraviolet (UV) light in advance. The results demonstrated that water droplets could quickly spread onto the surface of the patterned TiO2 film, resulting in a low CA. The patterned TiO2 film with the lowest period of 2 mu m showed the lowest CA of 2 degrees within 3 s. This indicated that the patterned TiO2 film had the good superhydrophilicity without any UV activation. The wetting behavior of the patterned TiO2 film followed the Cassie impregnating wetting regime, and the dynamic to hydrophilic state was attributed to the capillary effect. The patterned TiO2 film also had the non-UV induced anti-fogging performance and exhibited a good photocatalytic activity to decompose methyl orange pollutant. (C) 2018 Elsevier B.V.
