Abstract
A nanocarbon separation device includes a separation tank that is configured to accommodate a dispersion liquid including nanocarbons, a first electrode that is provided at an upper part in the separation tank, a second electrode that is provided at a lower part in the separation tank, an evaluation unit that is configured to evaluate a physical state or a chemical state of the dispersion liquid, and a fractionation unit that is configured to fractionate the dispersion liquid based on the physical state or the chemical state.
Claims11
A nanocarbon separation device, comprising:
- a separation tank that is configured to accommodate a dispersion liquid including nanocarbons;
- a first electrode that is provided at an upper part in the separation tank;
- a second electrode that is provided at a lower part in the separation tank;
- an evaluation unit that is configured to evaluate a physical state or a chemical state of the dispersion liquid;
- and
- a fractionation unit that is configured to fractionate the dispersion liquid based on the physical state or the chemical state.

A nanocarbon separation method, comprising:
- injecting a dispersion liquid including nanocarbons into a separation tank;
- separating the metallic nanocarbons and the semiconducting nanocarbons by applying a direct current voltage between a first electrode provided at an upper part in the separation tank and a second electrode provided at a lower part in the separation tank, to cause metallic nanocarbons included in the dispersion liquid to move toward the first electrode, and to cause semiconducting nanocarbons included in the dispersion liquid to move toward the second electrode;
- evaluating a physical state or a chemical state of the dispersion liquid;
- and
- fractionating the dispersion liquid based on the physical state or the chemical state.
