▎ 摘　　要

NOVELTY - Manufacturing graphene involves: preparing a carrier member on which the graphene is formed on one surface; exposing the graphene to dopant vapor to dope the graphene; transferring the doped graphene onto a target member; and removing the carrier member. USE - The method is useful for manufacturing graphene (claimed) used in a display device, an electronic device, a photoelectric device, a battery, and a solar cell. ADVANTAGE - The method produces high quality graphene with an improved electrical characteristic in large quantities. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is manufacturing a graphene film, which involves: preparing a roll-type heat-releasable film in which the graphene film is formed on one surface; exposing the graphene film to dopant vapor to dope the graphene film; transferring the doped graphene film onto a roll-type target film; and removing the heat-releasable film, where the operations are performed in one direction according to a roll-to-roll method.
