Resumen de: WO2021014896A1

The present invention addresses the problem of providing: a method for separating raw material carbon nanotubes into carbon nanotubes having fewer defects than before separation and carbon nanotubes having more defects than before separation, and recovering the carbon nanotubes; carbon nanotubes having fewer defects than before separation, obtained by said method; and a method for evaluating the crystallinity of the carbon nanotubes before separation. In the present invention, by utilizing the fact that the amount of a surfactant that is adsorbed on carbon nanotubes that include a large quantity of defects is decreased, carbon nanotubes that include a large quantity of defects are selectively adsorbed on a hydrogel including a hydrophobic group, and carbon nanotubes having few defects, which are not adsorbed, are thereby isolated. The concentration of defects included in the raw material carbon nanotubes is estimated by varying the dispersion time to determine the ratio of the carbon nanotubes having few defects and the carbon nanotubes having a large quantity of defects, obtained by the aforementioned method.
