An exemplary method for substantially non-chemically-reactive separation of nanomorphic
carbon species (140) comprises inter alia the steps of suspending a nanomorphic
carbon sample (100) in an aqueous surfactant suspension (110), adding
nanoparticles to the sample suspension (115), sonicating the sample (120),
centrifugating the sample suspension (125) and decanting off 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 via at least partial removal
of amorphous carbon contaminants.
