Abstract

Persistence length of multiwalled carbon nanotubes (MWCNTs) is studied using three-dimensional analysis of MWCNT individual particles, employing scanning electron microscopy with various view angles and a capillary viscometer. The root-mean-squared end-to-end distance of MWCNTs follows random-coil scaling in spite of their static bending points. The static bending persistence length (l_sp) of the MWCNTs is estimated to be 271 nm. The intrinsic viscosity of the MWCNTs follows the wormlike coil model when the dynamic bending persistence length (l_p) is replaced by the static bending persistence length (l_sp).
