▎ 摘　　要

NOVELTY - Preparation of three-layered vesicular polyaniline/graphene composite material involves preparing silica/polyaniline composite with adjustable layer using silica with adjustable layers as hard template and aniline as raw material by in-situ polymerization, etching silica of composite using hydrogen fluoride and obtaining three-layered vesicular polyaniline, and then self-assembling graphene oxide on surface of three-layered vesicular polyaniline and reducing hydrothermally at high temperature. USE - Preparation of three-layered vesicular polyaniline/graphene composite material used for supercapacitor (all claimed). ADVANTAGE - The method efficiently and economically provides three-layered vesicular polyaniline/graphene composite material by simple process with high operatability.
