A fluorocarbon-based coating film and method of manufacturing the same.

摘要

Disclosed is a step of contacting a substrate having a surface containing hydroxyl groups with a non-aqueous solution containing a material having a chrolosilyl group, a step of coating the substrate with a non-aqueous solvent containing a compound having a fluorocarbon group and a chlorosilane group or a solvent containing a compound containing a fluorocarbon group and an alkoxysilane and a step of baking the substrate after the contacting and coating steps a fluorocarbon-based polymer coating film chemically bonded to the substrate surface can be obtained. Wherein the hydroxyl groups on the substrate surface and chlorosilyl groups of the material having a chrolosilyl group are reacted to form a thin film having a large number of silanol groups (-SiOH) capable of connecting the polymer coating film to the substrate.
