dc.description.abstract | We report here scission of bamboo-shaped multi-walled carbon nanotubes (BS-MWCNTs) under ultrasonication. As the applied sonication energy increases, mean length of BS-MWCNTs decreases. When sonication energy increases over 500 J/mL, the length of BS-MWCNTs no longer decreases; the limited scission length (L-0) is about 1.7 mu m for BS-MWCNTs with diameter between 50 and 100 nm. From the L-o of BS-MWCNTs, their tensile strength (sigma*) is calculated and found to be smaller than that of multi-walled carbon nanotubes (MWCNT5). In addition, exponential decrease of the length of BS-MWCNTs with increasing sonication energy is observed, which is distinguished from typical power law dependence of sonication-induced scission of MWCNTs. These exclusive characteristics in the scission of BS-MWCNTs under ultrasonication are regarded to result from weak binding at discontinuous graphene sheets obtained from forming compartment structures of BS-MWCNTs during growth.
