  • Chirality-based separation of carbon nanotubes
    Publication number: 20100111814
    Abstract: A mixture of carbon nanotubes is separated into fractions that are enriched with a desired chirality by exposing a solution or suspension of the carbon nanotubes to a separation medium. A portion of the mixture forms complexes with, and becomes attached to, the separation medium. Exposure to other reagents results in dissociation of the complexes and release of the nanotubes from the separation medium.
