▎ 摘　　要

NOVELTY - Manufacture of self-supporting graphene film (FSG) involves horizontally arranging a substrate (S) provided with a through hole (H), dropping gallium droplet (LG) on the substrate such that through holes are closed, placing the substrate in a chamber, introducing a mixed gas of a carrier gas and a raw material gas, heating with a predetermined temperature profile to form graphene film (G), removing the droplets and forming graphene film as self-supporting graphene film. USE - Manufacture of self-supporting graphene film. ADVANTAGE - The self-supporting graphene film can be produced efficiently. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view explaining manufacture of graphene.
