▎ 摘　　要

NOVELTY - Composite material comprises fluorinated graphene oxide and poly(3-(4-fluorophenyl)thiophene) which is deposited on the surface of the fluorinated graphene oxide. USE - The composite material is useful for preparing supercapacitor electrode and lithium ion battery (claimed). ADVANTAGE - The composite material can be prepared simply, and is easy to use and suitable for industrial production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method for preparing the composite material, which involves adding the fluorinated graphene oxide in dispersing agent for ultrasonic dispersion, forming a suspension with a concentration of 0.2-2 g/l, adding oxidant to the suspension, performing ultrasonic dispersion, where the mass ratio of the fluorinated graphene oxide to the oxidant is 1:5-1:50, adding the dispersing agent solution of the poly(3-(4-fluorophenyl)thiophene) to the suspension under stirring condition and stirring continuously, where the mass ratio of the fluorinated graphene oxide to the poly(3-(4-fluorophenyl)thiophene) is 1:0.5-1:15, filtering the mixed solution, washing the product, and vacuum drying the product.
