Thermal Behavior of Raw and Purified SWNT Samples: XRD Studies
IIE Annual Conference
(2010)
Abstract
The thermal behavior of as-produced and purified single-wall carbon nanotube (SWNT) samples was investigated
using powder x-ray diffraction (XRD). XRD profiles were collected with increasing and decreasing temperatures in
air at the following steps: 25, 100, 300, and 450ºC. At room temperature, the raw SWNTs sample profile showed the
2D triangular lattice peaks associated with the SWNT bundles. However, the purified SWNTs sample profile had a
less distinct (10) peak, assumed to be due to adsorption of air into the SWNTs. The rope’s 2D lattice constant and
the SWNTs average diameter were estimated at 18.0 Å and 14.8 Å, respectively.
