ABSTRACT
We demonstrate the functionalization of single-walled carbon nanotubes (SWNTs) using a glow discharge for generating atomic or molecular radicals. A 30-s exposure to a cold plasma of H[sub 2] results in near-saturation coverage of SWNT with atomic hydrogen. Functionalization of SWNTs with atomic hydrogen is confirmed by an infrared band at 2924 cm[sup -1], characteristic of C-H stretching mode. A corresponding decrease in the ultraviolet absorption is also observed which is due to a loss of some conjugated C-C π bonds in hydrogen covered SWNTs.
