▎ 摘 要
NOVELTY - Method for preparing twisted graphene by polymer spiral growth, involves (a) uniformly mixing oxidant, graphite and concentrated sulfuric acid in a mass volume ratio of (0.05-5)g:(0.01-1)g:10 ml, and leaving still, (b) centrifuging the mixture to obtain a solid component after separation, and adding to monomer acid solution to initiate a polymerization reaction, and (c) washing the reaction product, ultrasonically processing, centrifuging, and freeze-drying the supernatant to obtain the graphene. USE - The method is useful for preparing twisted graphene by polymer spiral growth. ADVANTAGE - The method utilizes the spiral growth tendency of polymer molecules between graphite layers to drive the rotation of graphene sheets to produce graphene with torsion structure, easily adjusts the graphene torsion angle by controlling the process conditions of the polymerization reaction, is safe and controllable, and consumes less time and energy.
