摘要
(WO2017126777) A method for manufacturing carbon nanotube pellets, according to the present invention, enables manufacturing of pellets of which the dispersion characteristic with respect to a solvent is improved by reducing the particle size of carbon nanotubes included in the pellets through repetition of an extrusion step.  The present invention provides carbon nanotubes in a pellet form rather than carbon nanotubes in a powder form thereby improving various problems which can be caused by scattering of powder, and the carbon nanotubes are more advantageous in terms of transporting, carrying, and enhancing due to high apparent density thereby allowing more effective application in manufacturing of a carbon nanotube composite material.
