Abstract
A nanocarbon separation method includes: preparing a nanocarbon dispersion liquid in which nanocarbons and a non-ionic surfactant are dispersed in a solvent; injecting the nanocarbon dispersion liquid into a separation tank; applying a direct current voltage to a first electrode provided at an upper part of the interior of the separation tank and a second electrode provided at a lower part of the interior of the separation tank and generating a pH gradient in the nanocarbon dispersion liquid inside the separation tank, and separating metallic nanocarbons and semiconductor nanocarbons included in the nanocarbon dispersion liquid.
