  • Surfactant-based purification of nanotubes
    Patent number: 7781635
    Abstract: A mixture and method of using such mixture is provided for purifying carbon nanotubes. A substituted imidazolium cation is utilized to suspend carbon nanotubes in a nonpolar liquid. A polar solvent immiscible with the nonpolar liquid is mixed in to remove soot from the suspension, allowing recovery of the nanotubes. The relative gentleness of the separation provides nanotubes that are undamaged and unoxidized. The components of the mixture are economically advantageous for this use and the method is simple compared to other nanotube purification methods.
