▎ 摘　　要

NOVELTY - Graphite powder and supercritical carbon dioxide are mixed to obtain slurry. The obtained slurry is pressurized to obtain micronized graphite powder. The undifferentiated graphite powder is reacted with supercritical carbon dioxide to obtain carboxylated graphene. Carboxylated graphene is then separated from carbon dioxide by dispersing in a solvent. The manufacturing method comprising the graphene. USE - Manufacture of graphene (claimed). ADVANTAGE - The method efficiently provides graphene with high productivity, without affecting the environment. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for equipment for continuously manufacturing graphene.
