Characterization of TiO_2 deposited fabrics and their light transmittance

Nanoscale titanium dioxide(TiO_2) functional films were prepared on the surface of nonwoven polyester fabric at room temperature by DC reactive magnetron sputtering process.The surface morphology and the compositional properties of TiO_2 films were characterized by atomic force microscope(AFM) and X-ray photoelectron spectroscopy(XPS).The transmission properties of the fabrics with TiO_2 films prepared under different sputtering times were analyzed.The test results showed that the compositional properties changed little in the growing of films,but the growing rate and the surface morphology changed evidently.The increase of the sputtering time led to the increase in the continuity and compactness of TiO_2 films.The ultra-violet(UV) absorption by the polyester nonwoven fabric with TiO_2 films was enhanced by increasing the sputtering time within a proper range.
