▎ 摘　　要

NOVELTY - Graphene-based composite fiber is claimed. The graphene-based composite fiber is obtained by taking graphene oxide, polymer and cellulose as raw materials, and carrying out electrostatic spinning process. USE - The graphene-based composite fiber is useful as electrode material for super capacitor (claimed). ADVANTAGE - The method: solves the electrical conductivity of existing polymer fiber, which greatly limits potential as electrode material. The graphene-based composite fiber: exhibits better capacitance performance and flexibility; and utilizes flexible super capacitor which has high capacity, excellent rate performance and strong stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene-based composite fiber, comprising (i) adding polymer and cellulose into organic solvent, stirring until uniformly dispersed, (ii) adding graphene oxide, then dispersing ultrasonically to obtain spinning solution, and (iii) subjecting spinning solution to electrostatic spinning under high pressure to obtain final product.
