▎ 摘　　要

NOVELTY - A gas barrier film has a primary graphene layer formed on a macromolecular film, and a membranous polymer film. USE - Gas barrier film is used for flexible substrate (claimed) for display panel. ADVANTAGE - The gas barrier film has excellent heat resistance, illumination and physical properties, and is economically manufactured by a simple process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of gas barrier film, which involves forming the graphene layer on the membranous polymer film by spin coating, dip coating, solvent casting, chemical vapor deposition, slot die coating and/or spray coating of graphene solution on macromolecular film.
