Abstract: Provided is a manufacturing method of a graphene-based liquid crystal fiber including: polymerizing a first aromatic monomer on a graphene-based compound to prepare a graphene composite in which a first aromatic polymer is surface-polymerized on the graphene-based compound; wet-spinning the graphene composite to manufacture a hydrogel fiber; and polymerizing a second aromatic monomer on the hydrogel fiber to fill pores of the hydrogel fiber with a second aromatic polymer.
