Abstract: PURPOSE: A graphene composite nanofiber and a manufacturing method thereof are provided to secure the excellent mechanical property and electrical property of a graphene. CONSTITUTION: A graphene composite nanofiber contains multiple graphenes concentrated on one side inside a polymer nanofiber or a carbon nano fiber with the diameter of 1~1,000 nanometers. The graphenes are either monolayer graphenes or multilayer graphenes. A manufacturing method of a graphene composite nanofiber comprises the following steps: preparing a spinning solution containing the graphenes; and spinning the spinning solution.
