▎ 摘　　要

NOVELTY - Fractionating graphene material comprises preparing graphene material dispersion, where the graphene material is graphene, graphene oxide or graphene quantum dot; and subjecting the graphene material dispersion to electrophoresis; and sampling every 15 minutes once at the electrode side, to obtain different sized graphene material; where the electrophoresis voltage gradient is 8-30 V/cm, and the electrophoresis time is 2-4 hours. USE - The method is useful for fractionating graphene material (claimed).
