▎ 摘  要

NOVELTY - Extracting graphene particles in graphene regenerated cellulose fiber involves using sodium hypochlorite solution or copper ammonia solution as dissolving reagent to dissolve graphene regenerated cellulose fiber, and separating insoluble graphene solid particles by centrifugal effect. USE - The method is used for extracting graphene particles in graphene regenerated cellulose fiber. ADVANTAGE - The method has simple operation, low cost, common chemical reagent, simple configuration, proper reagent concentration, small viscosity, convenient centrifugal separation and complete fiber dissolution, and no flocculent fiber macromolecule precipitation during dissolution and centrifugation process. The product has no fiber impurities.
