▎ 摘　　要

NOVELTY - A graphene/polythiophene derivative composite material is prepared by ultrasonically dispersing graphite oxide and thiophene derivative monomer in dilute sulfuric acid solution (0.2 mole/l) to obtain a mixed solution of graphene oxide and thiophene derivative monomer, adding ammonium persulfate to the mixed solution and stirring, putting the stirred solution into a hydrothermal reaction kettle for 8-15 hours at 150-180 degrees C and filtering to obtain a graphene/polythiophene derivative composite material. USE - Graphene/polythiophene derivative composite material for an electrode of a super capacitor or lithium ion battery. ADVANTAGE - The material has high discharging performance, cycle life and thermal stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing a graphene/polythiophene derivative composite material. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating a method for preparing a graphene/polythiophene derivative composite material. '(Drawing includes non-English language text)'
