Abstract
The method for producing carbon nanotube pellets according to the present invention can reduce the particle size of the carbon nanotubes contained in the pellet by a repetitive extrusion process to produce pellets having improved dispersion characteristics in a solvent. The present invention can improve the problems of the change of the content generated by scattering of powders and safety issues by using carbon nanotubes in the form of pellet. And since the density of the pellet form is higher than that of the powder form, transport, transfer and improvement become easier. Therefore, it can be more effectively applied to the manufacturing of composite materials.
