▎ 摘　　要

NOVELTY - Preparation of high strength graphene fiber involves preparing a spinning solution comprising graphene oxide and polymer in a mixed solvent, spinning the solution in a coagulation bath to produce graphene oxide fibers and heat-treating the fiber. The weight of the polymer is less than or equal to the weight of the graphene oxide. USE - Preparation of high strength graphene fiber used for composite fiber (claimed). ADVANTAGE - The method produces composite fiber having high electroconductivity and mechanical strength with reduced amount of polymer. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for high strength composite fiber.
