▎ 摘　　要

NOVELTY - A graphene-modified aniline-pyrrole copolymer electrode material comprises 1-4 pts. wt. modified nitrogen-phosphorus-co-doped graphene, 16-20 pts. wt. pyrrole, 23-32 pts. wt. aniline, and 44-60 pts. wt. ammonium persulfate. USE - Graphene-modified aniline-pyrrole copolymer electrode material for supercapacitor. ADVANTAGE - The graphene-modified aniline-pyrrole copolymer electrode material has abundant pores, three-dimensional network structure, enhanced compatibility, improved conductivity, and excellent double-layer capacitance and Faraday pseudocapacitance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the graphene-modified aniline-pyrrole copolymer electrode material, which involves using 0.5-1 mol/L hydrochloric acid solution.
