PHOTO-INDUCED HYDROPHILIC ARTICLE AND PRODUCTION METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a method for imparting a photo-induced hydrophilic surface to a substrate by forming a photo-induced hydrophilic coating on the substrate by spray pyrolysis, chemical vapor deposition or magnetron sputter vacuum deposition, and to provide an article obtained thereby.SOLUTION: A photo-induced hydrophilic coating can have a thickness of 50Å-500Å, a root mean square roughness of less than 5, preferably less than 2, and a photocatalytic activity of less than 3.0×10cmmin±2.0×10cmmin. The substrate includes a glass substrate containing a glass sheet and a continuous float method glass strip.
