METHOD FOR MANUFACTURING BLOCK COPOLYMER USING GRAPHENE FILM AND BLOCK COPOLYMER MANUFACTURED BY THE SAME

摘要

PURPOSE: A manufacturing method of a block copolymer film is provided to manufacture a block copolymer film in which a nano area is arranged to be perpendicular to a surface even on a non-flat substrate, because of mechanical flexibility and elongation, etc which are inherent properties of a graphene film. CONSTITUTION: A manufacturing method of a block copolymer film comprises: a step of laminating the graphene oxide film on a substrate; a step of manufacturing a graphene film by reducing the laminated graphene oxide film; a step of laminating a block copolymer on the graphene film, and self-assembling the block copolymer. The lamination of the graphene oxide film is conducted by spin-casting the graphene oxide solution on the substrate. The reduction of the graphene oxide film is conducted by heat treatment or chemical treatment.
