BS PD ISO/TS 11888:2017 describes methods for the characterization of mesoscopic shape factors of multiwallcarbon nanotubes (MWCNTs). Techniques employed include scanning electron microscopy (SEM),transmission electron microscopy (TEM), viscometry, and light scattering analysis.This document also includes additional terms needed to define the characterization of static bendingpersistence length (SBPL). Measurement methods are given for the evaluation of SBPL, which generallyvaries from several tens of nanometres to several hundred micrometres.Well-established concepts and mathematical expressions, analogous to polymer physics, are utilizedfor the definition of mesoscopic shape factors of MWCNTs.Cross References:ISO 9276-6:2008 Ed 1ISO/TR 12885:2008 Ed 1ISO/TS 80004-3:2010
