METHOD FOR MANUFACTURING HYDROPHILIC COATED GLASS, WHICH CAN MAINTAIN HYDROPHILICITY DUE TO PHOTOCATALYTIC FUNCTION OF TITANIUM DIOXIDE AND HYGROSCOPIC PROPERTY OF SILICA

摘要

PURPOSE: A method for manufacturing hydrophilic coated glass is provided to show and maintain hydrophilicity resulting from a photocatalytic function of titanium dioxide and hygroscopic property of silica, and to improve the restorability of hydrophilicity. CONSTITUTION: The method for manufacturing hydrophilic coated glass comprises coating the glass surface with titanium dioxide and silica. Particularly, the method comprises the steps of: coating glass with a titanium dioxide solution and heat treating it at 400-600 deg.C for 1-2 hours; and coating the surface of glass coated with titanium dioxide with a silica solution and heat treating it at 200-600 deg.C for 20 min-1 hour. The hydrophilic coated glass has a double hydrophilic coating layer formed of a titanium dioxide layer having a thickness of 0.1-0.5 micrometers and a silica layer with a thickness of several angstroms.
