▎ 摘  要

NOVELTY - Preparing graphene involves drying graphite powder, adding organic solvent into adhesive, stirring uniformly and diluting adhesive. The drying graphite powder is added to adhesive after diluted, then stirred uniformly to prepare adhesive of graphite powder. The adhesive is bio-adhesive. The graphite powder-containing adhesive from back roll is added to middle roll to three-roll mill to adjust distance between front roll and middle roll. The adhesive containing graphite powder for grinding to obtain exfoliated graphite powder. The exfoliated graphite powder is purified to obtain graphene. USE - Method for preparing graphene. ADVANTAGE - The method enables to prepare graphene that has high efficiency, is suitable for large-scale production, and in simple manner.
