▎ 摘  要

NOVELTY - The method involves obtaining (S1) an adhesive opening and closing device. The adhesive opening and closing device includes one pair of adhesive plates, and one pair of the adhesive plates moves toward and away from each other, to realize the adhesive opening and closing operation. The viscous liquid and the graphite material are mixed (S2) to obtain the mixture to be peeled off. The mixture to be stripped is placed (S3) between a pair of bonding plates. A pair of the bonding plates is made (S4) to move toward and away from each other, to repeat the bonding and opening and closing operations, to realize the peeling of graphene and grapheme is obtained. The materials detached from the bonded plates during the pair-bonded opening and closing operation are recycled and transported (S5) back to between a pair of the bonded plates. USE - Method for bonding and opening and peeling off grapheme for grapheme preparation. Uses include but are not limited to optical, electrical, mechanical, micro-nano processing, energy, biomedicine and drug delivery. ADVANTAGE - The method enables recycling viscous liquid and organic reagent and repeatedly using, high efficiency and environment-friendly, low cost, and easy for industrial production. The graphene obtained by the method belongs to the graphene material, and is recycled and repeatedly used, and has high efficiency.
