Abstract
According to the present invention, a carbon nanotube structure can be manufactured by merely a simple process in which carbon nanotubes are pulverized and mixed in a dispersion solvent without a dispersant, followed by freezing, and then the dispersion solvent is removed. Such a method does not require a dispersant and a binder so that the manufactured carbon nanotube structure can be composed of only carbon nanotubes, and does not depend on the other additives to form the carbon nanotube structure so that there is little possibility of damage and contamination of the structure during the collection procedure of the structure after the formation of the structure.
