NOVELTY - A graphene/polyaniline/manganese dioxide ternary composite electrode material preparing method involves taking graphite oxide and potassium permanganate and dispersing with deionized water to obtain graphene oxide solution. The obtained solution is added with potassium permanganate, stirred and added diluted hydrochloric acid to obtain mixed solution, followed by dissolving aniline monomer with chloroform, adding mixed solution, performing ice surface polymerization, filtering, washing, dispersing with deionized water, adding hydrazine hydrate, stirring, filtering, washing and drying. USE - Method for preparing graphene/polyaniline/manganese dioxide ternary composite electrode material. ADVANTAGE - The method enables preparing the graphene/polyaniline/manganese dioxide ternary composite electrode material with better circulation property, high specific capacitance and high reliability in a simple manner. DETAILED DESCRIPTION - A graphene/polyaniline/manganese dioxide ternary composite electrode material preparing method involves taking graphite oxide and 0.474 g potassium permanganate at a ratio of 0.1-0.2:1 and dispersing with 50 ml deionized water to obtain graphene oxide solution. The obtained solution is added with potassium permanganate, stirred, added 1 mol/l diluted hydrochloric acid and adjusting pH value is equal to 1 to obtain mixed solution, followed by dissolving 5 mmole aniline monomer with 50 ml chloroform, adding mixed solution, performing ice surface polymerization for 48 hours, filtering, washing with ethanol and deionized water, adjusting pH value is equal to 7 to obtain intermediate product, dispersing with 50 ml deionized water, adding 66 micro-liter hydrazine hydrate, stirring at 98 degrees C for 24 hours, filtering, washing with acetone, alcohol and deionized water, adjusting pH value is equal to 7 and drying at 60 degrees C for 24 hours to obtain finished product.
