Abstract
A method of providing a substrate with a thin film coating of multiple layers by a single immersion of a substrate having active hydrogens on its surface into a coating solution including two or more dissimilar hydrolyzable and condensable organometallic compounds, water, a solvent, and a base, the solution having undergone substantially no polymer growth, for a time sufficient to form in situ the film on the substrate, removing and drying the coated substrate.
