▎ 摘　　要

NOVELTY - Production of graphene oxide/graphene/carbon nanotube composite fibers involves preparing a graphene oxide/carbon nanotube dispersion solution, a graphene oxide/graphene dispersion solution or a graphene oxide/graphene/carbon nanotube dispersion solution, producing gel fibers by spinning the dispersion solution into a coagulating bath including coagulation component(s) (a) e.g. cetyltrimethylammonium bromide, sodium hydroxide and potassium hydroxide, and coagulation component(s) (b) e.g. polyvinyl alcohol, polymethylmethacrylate and polyethylene oxide, and drying the gel fibers. USE - Production of graphene oxide/graphene/carbon nanotube composite fibers. Uses include but are not limited to electronic material, heat-dissipating material, electrode of super capacitor, sensor, electrode of secondary battery, actuator, touch panel, flexible display, highly-efficient solar cell, heat-radiating film, coating material, seawater desalination filter, high-speed charger, etc. ADVANTAGE - The method enables production of graphene oxide/graphene/carbon nanotube composite fibers having excellent electroconductivity, thermal conductivity, insulation property and mechanical characteristics. DETAILED DESCRIPTION - Production of graphene oxide/graphene/carbon nanotube composite fibers involves preparing a graphene oxide/carbon nanotube dispersion solution, a graphene oxide/graphene dispersion solution or a graphene oxide/graphene/carbon nanotube dispersion solution, producing gel fibers by spinning the dispersion solution into a coagulating bath including coagulation component(s) (a) chosen from cetyltrimethylammonium bromide, chitosan, calcium chloride, sodium hydroxide and potassium hydroxide, and coagulation component(s) (b) chosen from polyvinyl alcohol, polymethylmethacrylate, polyethyleneimine, polyvinyl pyrrolidone and polyethylene oxide, and drying the gel fibers.
