Abstract:

The formation of a massive quantity of single-wall carbon nanotube (SWCNT) superbundles has been introduced through sonicating SWCNTs in tetramethylene sulfone/chloroform solution in which nitronium hexafluoroantimonate (NHFA) is dissolved. Most SWCNT bundles with the NHFA treatment are enlarged by about 10 times compared with those of the pristine sample. It is proposed that the formation of SWCNTs can occur in solution by formation of an SWCNT-intercalant charge complex. The specific surface area of the superbundle is almost doubled, while its micropore surface area is amplified by about 7 times. This development of microporosity results from the enhanced interstitial sites in the SWCNT superbundles.
