Moreover, it's flame retardant and conducts electricity, which would make it useful in tiny electronic devices. Ironically, the problem with most carbon nanotubes is that they're too small, or rather, too short--on the order of tens of microns long. Short nanotubes are difficult to incorporate into existing manufacturing processes and lack the high performance properties of long carbon nanotubes. They also tend to be delivered in powder form (think of graphite pencils). By contrast, Nanocomp's tubes stretch a few millimeters and the sheets are specially treated to keep them from shedding black specks of carbon.
