Abstract:
1. A carbon nanotube separation method comprising: a step of putting a separation medium for electrophoresis into a separation container, a step of putting a carbon nanotube sealed gel which comprises a gel and carbon nanotubes dispersed in the gel into the separation container, and a step of electrophoresis comprising electrifying the separation container containing the separation medium for electrophoresis and the carbon nanotube sealed gel, wherein: a semiconducting carbon nanotube region is formed in the carbon nanotube sealed gel, a mixed region of metallic carbon nanotubes and semiconducting carbon nanotubes is formed, a metallic carbon nanotube region is formed in the separation medium, and a proportion of the metallic carbon nanotubes to the semiconducting carbon nanotubes in the separation medium is larger than a proportion of the metallic carbon nanotubes to the semiconducting carbon nanotubes in the carbon nanotube sealed gel.
