▎ 摘  要

NOVELTY - The method involves dispersing graphene material by a dispersing device to obtain graphene dispersion, where graphite material is graphene particles or chemically modified graphene and dispersant is ethanol or Dimethylformamide. The graphene dispersion is mixed with paper pulp to obtain graphene-paper pulp mixed solution. The graphene-paper pulp mixed solution is pulped, sized, molded and dried to obtain a graphene-paper pulp based loudspeaker diaphragm. The dispersing device is used as a grinding and dispersing device. USE - Graphene-paper pulp based loudspeaker diaphragm preparing method. ADVANTAGE - The method enables using excellent characteristics of graphene and improving intensity and tone produced diaphragm. DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram illustrating a graphene-paper pulp based loudspeaker diaphragm preparing method. '(Drawing includes non-English language text)'
