Abstract
The Sonication method is widely used with surfactants to suspend individual single walled nanotubes in solution, and it is well known that sonication-induced tube cutting occurs. Recently, it is found out that ultrasonicated nanotubes yield simultaneous separation by tube length and diameter. Nanotubes that have been cut shortest possess the greatest enrichments of large-diameter species. In this study, we cut single walled carbon nanotubes using a ball milling method and find out similar behavior compared to the sonication process Cutting mechanisms are also investigated using continuum approaches.
