摘要：

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-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(-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 pi bonds in hydrogen covered SWNTs. (C) 2002 American Institute of Physics.
