摘要： In the present invention, by dry pulverizing carbon nanotubes to control wettability index of the carbon nanotubes, the maximum concentration of the carbon nanotubes that can be added to the dispersion solvent can be increased and the workability of the carbon nanotube dispersion can be improved. Further, from this, it is possible to more easily predict the maximum concentration of the carbon nanotubes that can be added to the dispersion solvent.

摘要： 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.
