摘要
(KR10-1982572) According to a method for manufacturing a carbon nanotube pellet, a pellet having improved dispersion properties with respect to a solvent can be manufactured by decreasing the grain size of carbon nanotube included in a pellet through repeated extrusion processes. By providing not carbon nanotube in a powder form but carbon nanotube in a pellet form, various problems generated as powder is scattered can be solved. Also, since carbon nanotube in a pellet form has higher density than the carbon nanotube in a powder form, transfer, delivery and improvements can be performed more easily and the carbon nanotube in a pellet form can be effectively applied for manufacturing composite materials.
