▎ 摘　　要

NOVELTY - A graphene based polypyrrole pseudo capacitance supercapacitor electrode material is obtained by ultrasonically dispersing graphite oxide in distilled water for 0.5-1 hour and adding polystyrene sulfonate, heating at 60-80 degrees C for 1-2 hours, followed by cooling, filtering, adding hydrazine hydrate, heating at 100 degrees C for 1 hour, and washing to obtain graphene nanosheet. USE - Graphene based polypyrrole pseudo capacitance supercapacitor electrode material. ADVANTAGE - The material has good conductivity, large surface area, good chemical stability, good pseudo capacity and excellent capacitive performance.
