▎ 摘　　要

NOVELTY - Carbonized fiber or graphene composite preparation involves stripping graphene oxide chemically, and then processing the prepared graphene oxide ultrasonically to prepare graphene oxide colloid. The prepared graphene oxide colloid is coated on outer surface of the organic fiber to prepare an organic fiber or graphene oxide composite. The prepared organic fiber or graphen oxide composite is carbonized. USE - Method for manufacturing carbonized fiber or graphene composite (claimed) for use in water treatment, electrode carrier for energy storage, and supporter for all kinds of catalyst. ADVANTAGE - The method manufactures the carbonized fiber or graphene composite in a simple and cost-effective manner with excellent electrochemical characteristic and physical properties. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic scanning electron microscopic photograph of the manufactured carbonized fiber or graphene composite.
