THIN FILM MATERIAL AND METHOD FOR PREPARATION THEREOF

摘要

A thin film material which comprises a polymer thin film layer having a hydroxyl group or a carboxyl group on the surface thereof and a metal oxide thin film layer or an organic/metal oxide composite thin film layer which is bonded with the polymer thin film layer through said hydroxyl group or carboxyl group by a coordinate bond or a covalent bond, and has a whole thickness of 300 nm or less. The thin film material is suitable for general use, can have a structure precisely designed, can be prepared with case and simplicity, has high strength and exhibits self-supporting property.
