▎ 摘　　要

NOVELTY - The method involves dissolving aramid fiber into aramid nanometer fiber solution by utilizing a dimethyl sulfoxide/potassium hydroxide system. The aramid nanometer fiber solution is mixed with dimethyl sulfoxide dispersion of graphene oxide. An aramid nanometer fiber/graphene oxide composite film is placed in hydroiodic acid to perform reduction reaction. The aramid nanometer fiber/graphene oxide composite film is soaked in ethanol to remove hydroiodic acid. The aramid nanometer fiber/graphene composite film is utilized as a working electrode to soak in sulfuric acid solution of a conductive polymer monomer by utilizing a three-electrode system, where the conducting polymer monomer is aniline, pyrrole, thiophene or acetylene. USE - Method for preparing an aramid nanometer fiber/graphene/conductive polymer flexible composite electrode (claimed). ADVANTAGE - The method enables increasing tensile strength of an invented flexible composite electrode for about 83.29 megapascal, toughness for about 1.38MJ/m3, improving cyclic charge and discharging efficiency, capacitance retention rate for about 86% and ensuring high mechanical strength, electrochemical performance and cycle stability in an effective manner. DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram illustrating a method for preparing an aramid nanometer fiber/graphene/conductive polymer flexible composite electrode.
