▎ 摘　　要

NOVELTY - Coating of a substrate with a carbon-based material involves cleaning and activating a substrate by exposure of the substrate surface to vacuum UV (VUV) radiation and to an atmosphere comprising oxidizing radical species, coating the clean and activated substrate with graphene oxide coating, exposing the graphene oxide coating to VUV radiation under a dry atmosphere comprising inert gas(es) and forming a graphene-like coating comprising reduced graphene oxide and graphene. USE - Coating of substrate used for implant, scaffold for tissue engineering, product for biological warfare, product for corrosive environment, drug delivery, gene therapy, cancer therapy, bio-sensor, electrochemical biosensor, contact sensor, nanoelectromechanical sensor, chemical sensor and non-contact sensor, used in product e.g. electroconductive, tunable electric conductive device, lithium-ion battery electrode, energy storage device, supercapacitor, electromagnetic induction shield, transparent electronics, flexible electronics, nanoelectronics, nanoelectronics, nanogenerators, solar cells, fuel cells, hydrogen storage, photodetectors, organic LED, electronic displays, solid lubricants and diffusion barriers, method for providing corrosion protection, method for providing water-repellency to substrate, coating composition and method for providing anti-fouling properties to substrate (all claimed). ADVANTAGE - The method provides increased wettability, excellent diffusion barriers, excellent capability for corrosion protection, improved coating properties with long term stability and efficient healing-reducing VUV-assisted process for graphene oxide films. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) product; (2) method for providing corrosion protection; (3) method for providing water-repellency to the substrate; and (4) method for providing anti-fouling properties to the substrate.
