Disclosed is a method for mass-producing densified carbon nanotube fiber. The method includes preparing carbon nanotube fiber, swelling the carbon nanotube fiber by applying an acid solution thereto, and stretching the carbon nanotube fiber, coagulating the stretched carbon nanotube fiber so as to remove the acid solution present therein, and drying the coagulated carbon nanotube fiber.

Method for producing densified carbon nanotube fiber

The present disclosure provides an apparatus capable of continuously producing carbon nanotubes having high crystallinity, a low residual catalyst content and a high aspect ratio. The apparatus for producing carbon nanotubes includes: a reaction unit configured to synthesize carbon nanotubes (CNTs), a supply unit configured to supply a carbon source to the reaction unit through a supply pipe; and a collection unit configured to collect carbon nanotubes discharged from the reaction unit, wherein the reaction unit may include a chemical vapor deposition reactor.

Apparatus for continuously producing carbon nanotubes

Provided is a method for continuously manufacturing carbon nanotube fibers with high strength and high conductivity, which includes synthesizing carbon nanotube fibers by direct spinning; treating the carbon nanotube fibers with a strong acid while applying tension thereto; and washing the carbon nanotube fibers treated with the strong acid.
