▎ 摘　　要

NOVELTY - Preparation of carbon nanotube fibers involves preparing a carbon nanotube aggregate from a carbon source in the presence of a catalyst and a catalytically active agent, contacting the carbon nanotube aggregates with graphene oxide, and fiberizing the resultant carbon nanotube aggregates. USE - Preparation of carbon nanotube fibers (claimed) used as reinforcing agent for composite, and used in production of transparent conductive film. ADVANTAGE - The method provides carbon nanotube fibers having improved tensile strength within short time and without requiring any special equipment.
