ABSTRACT:
An exemplary method for substantially non-chemically-reactive separation of nanomorphic carbon species (150) comprises inter alia the steps of dissolving a crude nanomorphic carbon sample (100) in an organic solvent (110), centrifugation of the solvated sample (120) and decantation of the resulting supernatant (130). Disclosed features and specifications may be variously controlled, adapted or otherwise optionally modified to improve carbon nanospecies purification. An exemplary embodiment of the present invention representatively provides for non-oxidative cleaning of carbon nanotubes.
