A METHOD FOR PREPARING NANOCRYSTALLINE TRANSPARENT FILMS OF TUNGSTEN OXIDE

摘要

The object of the present invention is the preparation, through a sol-gel method, of a tungsten oxide (WO<SUB>3)</SUB>-based colloidal paste that allows providing transparent films on conductive glasses in an easy and cost-effective manner. Particularly, the present invention relates to a method for preparing a substrate coated with at least one thick layer of tungsten oxide, comprising at least one step of coating said substrate with a colloidal solution of tungsten oxide obtained with the sol-gel method, said colloidal solution being additioned with a thickener and a surfactant .
