Photochromic Fabric of WO3 and its Anti-UV Properties
The color of samples changed after illumination in the light from a high pressure mercury lamp, when depositing WO3 thin film on polyester fabrics by magnetron sputtering. indicate that the fabric has discolour properties. Placed in dark room for some time, the samples recovered to pre-illumination color, show that the reaction is photochromic.
