V. Other Characterization of Nanotubes

The nanomaterial activities at NASA-Johnson Space Center focus on carbon nanotube production, processing, characterization and their applications for aerospace systems. Single wall carbon nanotubes are produced by CVD, arc and laser methods. Characterization of the nanotube material is performed using the NASA-JSC protocol developed by combining analytical techniques of SEM, TEM, UV-VIS-NIR absorption, Raman, and TGA [1]. Possible addition of other techniques, such as XPS and ICP, to the existing protocol will be discussed. Changes in the quality of the material collected in different regions of the arc and laser production chambers are assessed using the original JSC protocol. The observed variations seem to indicate different growth conditions in different regions of the production chambers.
