▎ 摘  要

NOVELTY - Graphite crystals having average layer surface interval of 0.3354-0.35 nm computed from (002) diffraction lines measured by X-ray diffraction are stirred in water and/or organic solvent. The graphite layer is peeled from the surface of the graphite crystals, to obtain graphene. USE - Manufacture of graphene used for manufacturing film (claimed) for electronic device. ADVANTAGE - The method provides thin film having excellent transparency and electroconductivity, and large area. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) manufacture of film; and (2) manufacture of thin film containing graphene.
