▎ 摘　　要

NOVELTY - Manufacture of graphene involves preparing a dispersion solution containing graphene oxide, adding an amine to the dispersion solution to prepare a mixed solution containing graphene oxide, in which functional groups other than carboxyl groups are selectively reduced, and reducing. USE - Manufacture of graphene for graphene sheet (claimed). ADVANTAGE - Graphene having low surface roughness and excellent heat resistance is prepared efficiently. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for graphene sheet.
