▎ 摘　　要

NOVELTY - Method for extracting graphene particles in graphene polyester fiber involves dissolving the graphene polyester fiber using a mixture of trichloroacetic acid and trichloromethane as a dissolving agent and separating insoluble graphene solid particles by centrifugation. USE - The method is useful for extracting graphene particles in graphene polyester fiber. ADVANTAGE - The method adopts simple operation, common chemical reagent, simple configuration and dissolving and centrifuging process without flocculant fiber macromolecule precipitate, is low in cost and provides the extracted graphene particles that are free of fiber impurities.
