Reduced damage to carbon nanotubes during ultrasound-assisted dispersion as a result of supercritical-fluid treatment
A pre-treatment method of carbon nanotubes for ultrasound-assisted dispersion in a solution is reported. Compared to untreated nanotubes, supercritical-fluid (SCF)-treated carbon nanotubes were easily dispersed in an aqueous surfactant solution by using ultrasonicanon. The nanotubes are found to be less damaged and less shortened, which was confirmed by Raman spectroscopy and dynamic light scattering, respectively. Supercritical ethane was more effective than supercritical CO(2) in treating the carbon nanotubes. (C) 2011 Elsevier Ltd. All rights reserved.
