▎ 摘　　要

NOVELTY - A graphene-polypyrrole composite aerogel comprises graphene and polypyrrole composite. It has hole diameter of 1 nm to 4 mu m, porosity of 75.0-99.5%, density of 0.02-0.5 g/cm3, surface area of 100-900 m2/g, conductivity of 0.1-100 S/m and energy storage modulus of 2-25 MPa. USE - Graphene-polypyrrole composite aerogel used for preparing electrode material or adsorbent (claimed). ADVANTAGE - The aerogel has good comprehensive performance. The method is simple and suitable for large scale production, and has low consumption and green environmental protection. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene-polypyrrole composite aerogel comprising dispersing graphene oxide into acid or neutral water solution, forming stable graphene oxide dispersion liquid, placing at room temperature, adding pyrrole monomer, uniformly mixing, ultrasonically dispersing for more than 0.5 minute, standing at room temperature for more than 1 day to obtain graphene-polypyrrole composite hydrogel, and freeze-drying or supercritical drying.
