▎ 摘　　要

NOVELTY - Substrate for flexible photoelectron device comprises a flexible substrate and a conductive layer, where the conductive layer is graphene film. The flexible substrate is ultraviolet (UV) photo-curable adhesive comprising a free radical type UV photo-curable adhesive, positive ion type UV photo-curable adhesive and mixed system. USE - Used as a substrate for flexible photoelectron device. ADVANTAGE - The substrate solves the problem of roughness of conductive layer, improves the bonding force between the conductive layer and the flexible substrate and blocking ability of substrate to water and oxygen. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the substrate for flexible photoelectron device, comprising (i) cleaning the rigid substrate, whose surface roughness is less than 1 nm (e.g. copper foil, iron foil or nickel foil), and blow-drying using dry nitrogen, (ii) carrying out chemical vapor deposition to prepare graphene film on the clean rigid substrate, where the carbon source utilized in preparation condition includes methane, ethane, propane, butane, methanol, and/or ethanol, and growth condition of graphene film is 700-1000 degrees C under atmospheric pressure or negative pressure, (iii) spin coating or spray coating to prepare UV photo-curable adhesive on the graphene film, (iv) carrying out UV solidification curing process to the rigid base substrate for 30 seconds, (v) stripping the graphene film and the UV photo-curable adhesive from the surface of the rigid substrate to obtain flexible conductive substrate, and (vi) testing the transmittance, conductivity of the flexible substrate, and each parameter of the surface appearance. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the substrate for flexible photoelectron device.
