▎ 摘　　要

NOVELTY - A graphene/polyaniline spherical composite material comprises compounded graphene sheet and polyaniline sheet having spherical micron-sized structure and holes. USE - Graphene/polyaniline spherical composite material. ADVANTAGE - The method avoids agglomeration of graphene, and increases capacitance property and performance of composite material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of composite material comprising adding graphite oxide to high-temperature furnace to carry out expansion, adding to dispersant, ultrasonically-dispersing to obtain dispersed graphene, adding aniline, ultrasonically stirring, adding oxidizing agent and deionized water at - 5-5 degrees C, ultrafiltering, washing, and drying to obtain graphene/polyaniline spherical composite material; and soaking in acid solution, separating, and drying.
