▎ 摘　　要

NOVELTY - Graphene composite barrier film comprises an organic thin film (30) provided on an inorganic thin film (20), a graphene film, and a primer layer (40) provided between the organic thin film and the graphene film. USE - The graphene composite barrier film is useful for organic light emitting diode display. ADVANTAGE - The graphene composite barrier film has water permeability of less than or equal to 5x 10-5 g/m2/day with improved moisture barrier properties, high optical transmittance of greater than or equal to 85% and haze of less than or equal to 2%. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for manufacturing graphene composite barrier film, comprising forming the inorganic thin film on a substrate, forming an organic thin film on the inorganic thin film, forming a primer layer including at least one of a urethane resin and an epoxy resin on the organic thin film, and transferring the graphene film to the primer layer. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the cross-sectional view illustrating the method of manufacturing the graphene composite barrier film.
