Infrared Spectroscopy of Ultraviolet-Irradiated Carbon Nanotubes

Abstract

The possibility of using the UV irradiation for a functionalization of carbon nanotubes with different degrees of structural perfection is considered. In investigations, the method of infrared spectroscopy is used. A change in the number of functional groups under the short-term UV irradiation of specimens with multiwall carbon nanotubes is estimated by a change in the relative intensity of the IR spectral bands corresponding to vibrations of the functional groups in comparison with the relative intensity of the band corresponding to vibrations of the carbon atoms in graphite.
