Abstract Conductive thermoplastic nanocomposites are an interesting class of materials with various high-tech applications. The aim of this research is to investigate the effect of multi-walled carbon nanotube (MWCNT) concentration on the electrical conductivity of a thermoplastic polyurethane (TPU)/MWCNT. The electrical percolation threshold was found to be at 0.5 wt. % of MWCNT in a TPU comprised of poly(tetramethylene ether)glycol, 4,4 -methylene di(phenyl isocyanate), and butanediol. At the mentioned nanoparticle concentration, the electrical conductivity of the nanocomposite was more than 100 times that of the neat TPU. Moreover, the low-frequency plateau of electrical conductivity extended to higher frequencies at higher nanoparticle concentration.
