▎ 摘  要

NOVELTY - A compressible graphene/conductive polymer composite electrode material preparing method involves selecting graphene oxide as basic raw material, preparing 1-5 mg/ml graphene oxide solution, stirring with a reducing agent for 5-10 minutes and reducing at 80-150 degrees C for 24-40 minutes to obtain a treated material. The treated material is placed in a refrigerator to freeze for 4 hours after taking out, followed by thawing continuously, reducing at high temperature for 5 hours, washing with water for many times, drying, preparing 0.05 M conductive polymer monomer and 1 M sulfuric acid solution as electrolyte solution by electrochemical cyclic voltammetry under three-electrode system having voltage range of -0.2-0.8 V, scanning rate of 40 mV/s and cyclic voltammetry circulation of 30-500 cycles, washing with deionized water, and drying to obtain the finished product. USE - Method for preparing a compressible graphene/conductive polymer composite electrode material that is utilized in super capacitors and other energy storage devices. ADVANTAGE - The method enables preparing the compressible graphene/conductive polymer composite electrode material with better effect of controlling growth of polymer, improved specific capacity, better superelastic property and better supercapacitive energy, in a simple and rapid manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a compressible graphene/conductive polymer composite electrode material is prepared by the method.
