Title: METHOD FOR PRODUCING CARBON NANOTUBE FIBER AND CARBON NANOTUBE FIBER PRODUCED THEREBY
Abstract:
The present invention relates to a method for producing a carbon nanotube fiber, and a carbon nanotube fiber produced thereby, the method comprising: a step (S1) for producing a carbon nanotube assembly from a carbon source in the presence of a catalyst and a catalyst activator; a step (S2) for bringing the carbon nanotube assembly into contact with a graphene oxide; and a step (S3) for fiberizing the carbon nanotube assembly in contact with the graphene oxide.
