▎ 摘　　要

NOVELTY - The method involves using graphite electrode sheet as raw material, preparing expanded graphite powder by electrochemical treatment method, collecting the expanded Graphite powder prepared in step (1), placing it into a freeze-drying apparatus, freezing and drying for more than 30 hours at -40?? C, using suction filtration method to prepare graphene paper, placing the prepared graphene paper into an oven at 70-90?? C and drying overnight, taking the graphene paper as a substrate, preparing aniline solution, using three-electrode method to electrodeposit polyaniline graphene paper electrode on the graphene sheet. USE - Method for preparing a conductive polymer composite electrode based on graphene paper used in energy storage device. Uses include but are not limited to super capacitor electrode material e.g. polyaniline (PANI), polythiophene (PTH) and Faraday reaction capacitor. ADVANTAGE - The polyaniline graphene paper electrode has high doping rate, high conductivity, high specific capacitance and simple synthesis. It has simple technique, high efficiency, large capacitance, strong circulation stability, and long cycle life. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a conductive polymer composite electrode based on graphene paper.
