• Associated context:

  As seen in Table 1, the measured BET surface area for cut  SWNTs of 1180 m2‚g-1 is approximately double that of uncut  SWNT (and charcoal). Our value of 675 m2‚g-1 for the surface area of uncut SWNT is within the range of previous results in the literature.4,5 It is tempting to speculate that the increase in surface area from “cutting” SWNTs into shorter lengths arises from greater access to the interior walls of the cut tubes because of side-wall damage (and possibly end opening) during the fluorination/pyrolysis procedure.
