A Convenient Route to High‐Performance HDPE–CNT Conductive Nanocomposites by Control of Matrix Nucleation

Abstract

Abstract We show how styrene‐ethylene‐propylene‐styrene (SEPS) triblock copolymer uniquely reduces the electrical percolation threshold after matrix crystallization of conductive nanocomposites based on high viscosity HDPE with low amounts of pristine multiwall carbon nanotubes (CNT). Rheo‐dielectric and Flash DSC techniques are used to demonstrate that SEPS interferes with the nucleation ability of CNT on HDPE crystallization in a way that favors contacts between the nanotubes after crystallization as well as it improves CNT dispersion.
