Tuning the electrical percolation threshold of polymer nanocomposites with rod-like nanofillers
In this communication, a stochastic approach based upon Komori and Makishima's work has been used for predicting the electrical percolation threshold of cylindrical nanofillers with three-dimensional (3D) spatial orientations in a typical nanocomposite system. Specifically, the proposed model was able to predict the volume fraction based percolation threshold of nanofillers with a wide range of aspect ratios (10-1000), which was substantiated with a variety of experimental data sets obtained from the literature. The anisotropic behavior of 3D aligned nanofillers was successfully introduced via in-plane and out-of-plane orientation distributions. The percolation threshold values of nanofillers were also found to be comparable with those obtained from the stochastic model that has incorporated the excluded volume effect. (C) 2016 Elsevier Ltd.
