Multiwall Carbon

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.

Nanotube Films

By exploiting the dispersibility and rigidity of boehmite nanofibers (BNFs) with a high aspect ratio of 4 nm in diameter and several micrometers in length, multiwall-carbon nanotubes (MWCNTs) were successfully dispersed in aqueous solutions. In these sols, the MWCNTs were dispersed at a ratio of about 5–8% relative to BNFs. Self-standing BNF–nanotube films were also obtained by filtering these dispersions and showing their functionality. These films can be expected to be applied to sensing materials.
