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.

Claims

1. A fluorocarbon-based polymer lamination coating film comprising an adsorbed film formed as an inner layer and a cross-linked fluorocarbon-based polymer film formed as an outer layer on the surface of a substrate, wherein said substrate surface and said inner layer are bonded together with covalent bonds, and said inner layer and said outer layer are bonded together with cross-linking bonds.

2. A fluorocarbon-based polymer lamination coating film according to claim 1, wherein said inner layer is siloxane based monomolecular adsorbed film, and said substrate surface and said outer layer are bonded with covalent siloxane bonds.

3. A fluorocarbon-based polymer lamination coating film according to claim 1, wherein said inner layer is siloxane based polymer adsorbed film, and said substrate surface and said outer layer are bonded with covalent siloxane bonds.

4. A fluorocarbon-based polymer lamination coating film according to claim 1, wherein said inner layer is at least one of reaction product of a silane-based surface material selected from the group consisting of alkyl silane halide, alkenyl silane halide, alkynyl silane halide, alkoxyl-based silane, and those fluorine derivative compounds.

5. A fluorocarbon-based polymer lamination coating film according to claim 1, wherein the substrate is made of a member of a group consisting of metals, ceramics, plastics, and glass.
