Fabrication of Transparent Superhydrophilic TiO2 Nanofilm without UV-irradiation

摘要：

A transparent phase-pure anatase TiO2 nanofilm was prepared through magnetron sputtering method, and a subsequent annealing treatment awarded it the superhydrophilic characteristic. To make clear the mechanism of the heat-induced superhydrophilicity, the chemical composition and surface morphology of the film were investigated in detail and compared before and after the annealing treatment mainly by field emission scanning electron microscopy (FESEM), X-ray diffraction method (XRD), Raman spectroscopy, and X-ray photoelectron spectroscope (XPS). The results suggest that the probable mechanism is in accordance with the UV-induced mechanism, where the heat-induced surface oxygen vacancies and hydroxyl radicals play important roles for achieving the superhydrophilicity.
