NOVELTY - Preparation of metal ion-doped graphene oxide/polyaniline composite electrode material involves mixing graphite powder and concentrated sulfuric acid in three-necked flask, stirring at room temperature under ice bath for 30-60 minutes, adding sodium nitrate and potassium permanganate, reacting for 2-4 hours to precipitate, stirring for 2-4 hours under water bath at 35 degrees C, standing for 24-36 hours, adding distilled water, stirring for 20-40 minutes, performing ultrasonic dispersion for 1-2 hours, and adding 30% hydrogen peroxide to obtain golden brown solution. USE - Method for preparing metal ion-doped graphene oxide/polyaniline composite electrode material (claimed). ADVANTAGE - The method has different cluster shapes, and good electrical property. DETAILED DESCRIPTION - Preparation of metal ion-doped graphene oxide/polyaniline composite electrode material involves mixing graphite powder with particle size of 30m mu m and 95-98% concentrated sulfuric acid in three-necked flask, stirring at room temperature under ice bath for 30-60 minutes, sodium nitrate and potassium permanganate, reacting for 2-4 hours to precipitate, stirring for 2-4 hours under water bath at 35 degrees C, standing for 24-36 hours, adding distilled water, stirring for 20-40 minutes, performing ultrasonic dispersion for 1-2 hours, adding 30% hydrogen peroxide to obtain golden brown solution. adding hydrochloric acid to dissolve insoluble matter, centrifuging, performing dialysis, monitoring pH value to 6.8-7.2 to obtain graphene oxide.
