▎ 摘　　要

NOVELTY - Manufacture of graphene oxide-carbon nanotube-based conductive composite fiber involves dispersing graphene oxide in a solvent to produce a dispersion, adding a carbon nanotube dispersion to the dispersion, mixing, injecting the mixed solution into a polymer solution to form a composite gel comprising graphene oxide, carbon nanotubes and a polymer, removing the composite gel, washing, transferring the gel on a polymer film, and separating the transferred composite gel from the polymer film. USE - Manufacture of graphene oxide-carbon nanotube-based conductive composite fiber used for supercapacitor (all claimed). ADVANTAGE - The method enables efficient, simple and economical manufacture of graphene oxide-carbon nanotube-based conductive composite fiber with excellent mechanical property and electrical property.
