Method for producing laminated nano thin film of metal oxide film and polymer compound film, method for producing metal oxide nano thin film, and laminated nano thin film of metal oxide film and polymer compound film

摘要

A laminated nano thin film of a metal oxide film and a polymer compound film is obtained by hydrolyzing a metal alkoxide by adding water in a metal alkoxide solution in an amount 0.01 to 6 times the molar amount of the metal in the metal alkoxide solution. 2) The hydrolyzed metal alkoxide solution is spread on the surface of a non-aqueous solvent to obtain a metal oxide gel film. A solution of a polymer compound that reacts with or adsorbs to the gel film is developed on the surface of the aqueous solvent, 4) a laminated film of the gel film and the polymer compound film is formed, and 5) on the surface of the non-aqueous solvent. The laminated film of the gel film and polymer compound film to be formed is taken out and dried to obtain a laminated nano thin film of the gel film and polymer compound film.
