Method for preparing non-oxidized carbon nanotube dispersion through mechanical impregnation, and non-oxidized carbon nanotube dispersion prepared thereby

A method of preparing a non-oxidized carbon nanotube dispersion solution using mechanical impregnation, the method comprising:

• preparing a carbon nanotube dough by kneading carbon nanotubes in a bundle shape and alcohol so that the surface of each of the carbon nanotubes in the bundle shape is wet;
• preparing a carbon nanotube-binder mixture by mixing the carbon nanotube dough with a binder and applying a shear force to the mixture;
• and
• preparing a carbon nanotube dispersion solution in which each of the carbon nanotubes is debundled and dispersed by sonicating the carbon nanotube-binder mixture,
• wherein, after the alcohol penetrates between each of the carbon nanotubes during kneading, the binder penetrates between each of the carbon nanotubes during the preparation of the carbon nanotube-binder mixture, thereby causing mechanical impregnation.
