SEPARATION METHOD OF SEMICONDUCTING CARBON NANOTUBE AND METALLIC CARBON NANOTUBE

摘要

The present invention relates to a method for separating semiconducting carbon nanotubes and metallic carbon nanotubes. Specifically, the method for separating semiconducting carbon nanotubes and metallic carbon nanotubes according to the present invention uses multi-column chromatography and semiconducting carbon. A method for separating semiconducting carbon nanotubes and metallic carbon nanotubes with high purity by optimizing the concentration of the surfactant in the dispersion by using the difference in adsorption degree of the nanotubes and the metallic carbon nanotubes on the gel and surfactant. .
