▎ 摘　　要

NOVELTY - Graphene material size fractionation involves dispersing graphene material in solvent, obtaining graphene material dispersion liquid, passing through a porous membrane by applying external force, obtaining filtrate and retentate, and separating graphene material with different size. USE - Graphene material size fractionation (claimed). ADVANTAGE - The graphene material size fractionation is carried out by effective, environmentally-friendly and economical one-step process.
