Method for solution coating of inorganic superhydrophilic thin film

Abstract

A method of producing a silica-based superhydrophilic film. A coating formulation is provided, where the coating formulation includes an alkali metal silicate having a substantial portion of water removed therefrom, where the alkali metal silicate has a formula of M2O·nSiO2, and where M represents an alkali metal and n is a positive real number greater than zero. Furthermore, the coating formulation and an alcohol including a curing agent are mixed, where the curing agent includes an acid or an alkaline earth metal halide. Additionally, the coating formulation is dried to form the silica-based superhydrophilic film. Furthermore, a silica-based superhydrophilic film is produced according to such a method, where the silica-based superhydrophilic film includes an amine stabilizer.
