NOVELTY - A graphene-manganese dioxide nanosheets- polyaniline nanorods ternary material preparing method involves preparing graphene oxide, drying and filtering the resulting graphene oxide paper. The graphene oxide paper is immersed in hydroiodic acid and reduced. The paper is soaked in mixed solution of manganese acetate tetrahydrate and sodium sulfate and deposited. The nanosheets are cleaned and dried. Aniline monomer is poured into deionized water, followed by adding camphorsulfonic acid, mixing solution of aniline and ammonium persulfate and immersing the product in the obtained solution. USE - Method for preparing graphene-manganese dioxide nanosheets- polyaniline nanorods ternary material that is utilized as electrode material for super capacitor (claimed). ADVANTAGE - The method enables preparing graphene-manganese dioxide nanosheets- polyaniline nanorods ternary material with excellent electrochemical stability in simple, easy and cost-effective manner. DETAILED DESCRIPTION - A graphene-manganese dioxide nanosheets- polyaniline nanorods ternary material preparing method involves preparing graphene oxide through Hummer method, drying to a concentration of 0.5-l mg/ml suspension of 50-100 ml graphene oxide and vacuum filtering the resulting graphene oxide paper through frit funnel method. The graphene oxide paper is immersed in 40-45 mass% hydroiodic acid, reduced at 70-90 degrees C for 3-6 hours, washed with deionized water and ethanol, and vacuum dried for 2-4 hours. 0.1-0.5 M Manganese acetate tetrahydrate solution and 0.1-0.5 M sodium sulfate solution are mixed at a volume ratio of 1:1 under stirring. The graphene paper is soaked in the obtained solution, deposited with Autolab electrochemical deposition workstation through a three-electrode system at a constant voltage conditions at 0.5-I V for 200-900 seconds to obtain manganese dioxide nanosheets. The nanosheets are cleaned with deionized water and dried under vacuum for 5-10 hours. The three-electrode system is based on molybdenum film as counter electrode, silver/silver chloride as reference electrode and graphene paper as a working electrode. 1-1.5 ml Aniline monomer is poured into 60-80 ml deionized water, followed by adding 1.5-2.3 g camphorsulfonic acid, with rapid stirring for 1-3 minutes, dissolving 3-3.5 g, 30-40 ml ammonium persulfate in deionized water, stirring for 0.5-2 minutes, completely dissolving, mixing the solution of aniline and ammonium persulfate with a volume ratio of 2:1, rapidly stirring for 0.5-2 minutes, immersing the product in the obtained solution, allowing to stand for 2-5 hours and obtaining graphene-manganese dioxide nanosheets-polyaniline nanorods ternary material.
