Carbon nanotubes improve in properties, purity & price.(NANOTUBES: Close-Up)
Plastics Technology, November, 2007 by Sherman, Lilli Manolis
* New suppliers and manufacturing technologies continue to emerge in the burgeoning field of carbon nanofibers (CNFs) and single-walled carbon nanotubes (SWCNTs). Recent news includes North American availability of CNFs from Austria's Electrovac Group. Also, a low-cost process for making SWCNTs has been developed by the NASA Goddard Space Flight Center and has been licensed to three start-up companies that aim to make low-cost hollow SWCNTs available within a year.

Owing to the much higher cost of SWCNTs, most of the commercial activity in carbon nano-particles has involved multiwalled carbon nanotubes (MWCNTs), which are single tubes with five to 15 layers; and the closely related CNFs. As we reported in July (see Learn More),...
