METHOD FOR MANUFACTURING GRAPHENE OXIDE FIBER, GRAPHENE FIBER, AND GRAPHENE OR GRAPHENE (OXIDE) COMPOSITE FIBER BY USING ELECTRIC FIELD-INDUCED WET SPINNING PROCESS

摘要

The present invention provides a method for manufacturing a graphene oxide fiber or a graphene fiber, comprising the steps of: dispersing graphene oxide or graphene in a solvent so as to prepare a spinning solution; wet spinning the same in a coagulation bath in a state in which an electric field is applied in the discharge direction of the spinning solution, so as to manufacture a gel fiber; and drying the gel fiber.
