End-group and defect analysis of soluble single-walled carbon nanotubes
By use of solution phase mid-IR spectroscopy we are able to obtain an estimate for the ratio of the carbon atoms in the single-walled carbon nanotube (SWNT) backbone to the carbon atoms in the end-groups and at defect sites of the octadecylamido (ODA) functionalized soluble SWNTs (s-SWNT-CONH(CH2)(17)CH3). This analysis shows that the weight percentage of the octadecylamido functionality in the s-SWNTs is about 50%,
