NOVELTY - A graphene/polypyrrole/manganese dioxide ternary complex electrode material preparing method involves taking graphite oxide and potassium permanganate, dissolving graphite oxide with deionized water and ultrasonic dispersing to obtain oxidation graphite alkene solution. The obtained solution is added with potassium permanganate, stirred and added hydrochloric acid to obtain mixed solution, followed by adding pyrrole, dissolving with chloroform, performing interfacial polymerization, filtering, adding alcohol, dispersing with deionized water, adding hydrazine hydrate, stirring and filtering. USE - Method for preparing graphene/polypyrrole/manganese dioxide ternary complex electrode material for use in supercapacitor electrode material. ADVANTAGE - The method enables preparing graphene/polypyrrole/manganese dioxide ternary complex electrode material with better circulation property and specific capacitance and in a simple and reliable manner. DETAILED DESCRIPTION - A graphene/polypyrrole/manganese dioxide ternary complex electrode material preparing method involves taking graphite oxide and 0.0474 g potassium permanganate, dissolving graphite oxide with 50 ml deionized water and ultrasonic dispersing for 1 hour to obtain oxidation graphite alkene solution. The obtained solution is added with weighed potassium permanganate, stirred, added dropwise 1 mol/l diluted hydrochloric acid solution and adjusted pH value equal to 1 to obtain mixed solution. The obtained solution is added with 1 ml pyrrole, dissolved with 50 ml chloroform, followed by performing interfacial polymerization at 0-4 degrees C for 48 hours, filtering, adding alcohol, cleaning with deionized water, adjusting pH value equal to 7 to obtain intermediate product, dispersing with 50 ml deionized water, adding 66 microliters hydrazine hydrate, stirring at 98 degrees C for 24 hours, filtering, washing with acetone, adding alcohol, washing with deionized water, adjusting pH value equal to 7 and drying at 60 degrees C for 24 hours to obtain finished product.
