Abstract
A method of coating a substrate with a uniform, ultra-thin film of a polymer comprising immersing a substrate having active hydrogens on its surface in a solution comprising at least one hydrolyzable metal alkoxide of a polymeric network-forming cation, water, a solvent and a base, said solution having undergone substantially no polymer growth, for a time sufficient to form in situ said film on said substrate, removing and drying said coated substrate.
