Abstract
A substrate such as metal, ceramic, plastic, and glass material having a fluorine-based coating film having strong adhesion to a surface of the substrate wherein the substrate material comprises a monomolecular or polymer adsorption film formed on a base substrate surface and having siloxane bonds and a fluorine-based coating film provided on the adsorption film and a method of manufacturing a substrate material having a fluorine coating, which is simple and does not involve any electrolytic etching step which method comprises a step of forming a monomolecular or polymer adsorbed film having --Si-- bonds from dehydrochlorination or dealchoholation the bonded on the substrate surface and causing a silane-based surface active material, capable of reaction with an active hydrogen, to be brought in contact with the substrate surface, and laminating a fluorine-based polymer bonded by a cross-linking reaction process on the adsorbed film.
