▎ 摘　　要

NOVELTY - Manufacturing flake graphene by liquid phase exfoliation of graphite particles, comprises preparing a suspension of graphite particles in a solvent, and mixing it until a suspension of graphene flakes in the solvent is obtained from which unexfoliated graphite particles are then removed, where oil having a surface tension of 39-42 mN/m at room temperature is used as the solvent. USE - The method is useful for manufacturing flake graphene. ADVANTAGE - The method provides flake graphene which exhibits long-term stability (over 6 months) and good quality.
