▎ 摘　　要

NOVELTY - A graphene nanoplate (GNP) is prepared which involves preparing expanded graphite (EG); and exfoliating, grinding, or cracking the EG by colliding between the expanded graphite by a gas-phase high speed to crack the EG induced by gas-phase-collision. USE - The method is useful for preparing GNP used for preparing GNP paste (all claimed). ADVANTAGE - The method can prepare good quality of GNP. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a GNP prepared by preparing EG; and exfoliating, grinding, or cracking the EG by colliding the expanded graphite by a gas-phase high speed to crack the EG induced by gas-phase-collision; and (2) a GNP paste comprising GNP prepared by preparing EG; and exfoliating, grinding, or cracking the EG by colliding the expanded graphite by a gas-phase high speed to crack the EG induced by gas-phase-collision.
