▎ 摘　　要

NOVELTY - Preparation of graphene composite electrode involves immersing a collector in an aqueous solution of polyethyleneimine, surface-treating, sequentially immersing collector in poly(3,4-ethylene dioxythiophene):polystyrene sulfonate aqueous solution and an aqueous solution containing the dispersion of graphene and cationic surfactant, sequentially repeating the immersion processes, and drying in vacuum at 100-180 degrees C. USE - Preparation of graphene composite electrode (claimed). ADVANTAGE - The graphene composite electrode is produced by simple method.
