▎ 摘  要

NOVELTY - A graphene/conductive polymer composite electrode material preparing method involves mixing diluted hydrochloric acid, absolute ethyl alcohol and ammonium persulfate to obtain a solution-A, and stirring diluted hydrochloric acid, anhydrous ethanol, conductive polymer and graphene oxide ultrasonically to obtain solution-B. The solution-B is mixed with solution-A, followed by freezing resultant mixture, carrying out low temperature standing reaction, vacuum filtering, eluting with de-ionized water, absolute ethyl alcohol and n-hexane, vacuum drying, and grinding to obtain the finished product. USE - Method for preparing graphene/conductive polymer composite electrode material that is utilized in super capacitor. ADVANTAGE - The method enables preparing the graphene/conductive polymer composite electrode material with better effect of solving easy agglomeration due to large specific surface energy resulting in electrochemical performance lower than the theoretical value, large specific capacitance of conductive polymer, better circulation stability, high degree of polymerization and small agglomeration degree.
