Dispersion of carbon nanotubes and fullerene nanowhiskers by the liquid-jet cavitation method

摘要

A few papers suggesting the carcinogenicity of carbon nanotubes (CNTs) have been published recently. However, the CNTs are in general agglomerated and not always suited for their assessment of biological impact. In the present study, the liquid-jet cavitation method is examined for the dispersion of MWCNTs. It is shown that the liquid-jet cavitation method is useful to prepare isolated and well-dispersed MWCNTs. Further, it is also shown that the liquid-jet cavitation method is efficiently used to pulverize fullerene nanowhiskers into short and uniform pieces.
