▎ 摘　　要

NOVELTY - Wrinkled graphene-based capacitance composite material induced by ferric cation, is formed by using graphene oxide with large number of wrinkles on the surface under the induction of Fe3+ after hydrothermal treatment, and loading polypyrrole and titanium oxide nanoparticles between the surface wrinkles, where the particle size of polypyrrole is 200-300 nm, the particle size of TiO2 nanoparticles is 10-20 nm and the capacitor composite does not contain Fe. USE - Wrinkled graphene-based capacitance composite material induced by ferric cation is used for super capacitor as electrochemical element for storing energy by polarizing electrolyte developed from seventh and eighties of last century. ADVANTAGE - The composite material has excellent specific capacitance performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparing the wrinkled graphene-based capacitance composite material induced by ferric cation.
