▎ 摘　　要

NOVELTY - A method of manufacturing a graphene fiber, involves: forming a supporting fiber; forming a graphene oxide-containing solution; coating the supporting fiber with the graphene oxide-containing solution to form a graphene oxide composite fiber; and separating the supporting fiber from the graphene oxide composite fiber. USE - For manufacturing graphene fiber (claimed) applicable in various fields including an environment field and an energy field, for display, cathode material of lithium-ion battery, electrode material of electric double-layered capacitor, environmental filters, and biomaterials. ADVANTAGE - The method easily manufacturing a large-area graphene fiber having high strength, high flexibility, and high porosity.
