Title:
NANOCARBON SEPARATION METHOD
Document Type and Number:
WIPO Patent Application WO/2018/159001
Kind Code:
A1
Abstract:
The nanocarbon separation method according to the present invention comprises: a step for preparing a plurality of liquids which are of different specific gravities and at least one of which is a dispersion liquid having a mixture of nanocarbons of different properties dispersed therein; a step for sequentially injecting the plurality of liquids into an electrophoresis tank so that the specific gravity of the resultant liquid decreases from the lower side toward the upper side in the direction of gravitational force; and a step for separating the nanocarbon mixture by applying direct current electric potential to electrodes disposed in the upper part and the lower part of the electrophoresis tank so as to cause a portion of the nanocarbon mixture to move to the side of the electrode disposed in the upper part and to cause the remainder of the nanocarbon mixture to move to the side of the electrode disposed in the lower part.
