Abstract
A method of manufacturing a graphene fiber is provided. The method includes preparing a source solution including graphene oxide, supplying the source solution into a coagulation solution to form a graphene oxide fiber, reducing the graphene oxide fiber to form a primary graphene fiber, and Joule-heating the primary graphene fiber to form a secondary graphene fiber.
