▎ 摘  要

NOVELTY - A graphene-based fiber is manufactured by (a) mixing a 1st composition comprising a liquid-crystalline aromatic compound and a 2nd composition comprising a graphene-based material to prepare a blend mixture; and (b) spinning the blend mixture to obtain graphene-based fiber. USE - Manufacture of graphene-based fiber for manufacturing graphene-based carbon fiber (claimed). ADVANTAGE - The method manufactures graphene-based fiber with excellent thermal and electrical conduction characteristics, and superior mechanical properties. The graphene-based fiber and graphene-based carbon fiber exhibit a liquid crystal phase and have high crystallinity and orientation by spinning the blend mixture in which the liquid-crystalline aromatic compound is intercalated into the graphene-based material. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) manufacturing a graphene-based carbon fiber which involves further carbonizing the graphene-based fiber; and (2) graphene-based fiber comprising liquid-crystalline aromatic compound which is intercalated into graphene-based material. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the manufacture of graphene-based fiber and graphene-based carbon fiber.
