The preparation of finely dispersed and isolated MWCNTs for their safety evaluation was investigated by use of the fluid-jet cavitation method (FJCM). The used MWCNTs had the agglomerated structures combined by nodes. FJCM could partly cut the MWCNTs at the nodes and monodispersed MWCNTs were obtained, although the complete pulverization was not possible for heavily tangled MWCNTs. The fracture surfaces of MWCNTs showed both the convex and concave morphologies. A convex end showed a sharply-peaked morphology with a thickness of 14 nm. Those MWCNTs with pointed ends will be applicable to high-performance electron field emission devices.
