Modelling the DC electrical conductivity of polymer/carbon black composites

Modelling the DC electrical conductivity of polymer/carbon black composites Several DC electrical conductivity models have been proposed to explain the properties of composite materials.

Abstract

Several DC electrical conductivity models have been proposed to explain the properties of composite materials. In particular, generalized effective medium model was used, but, in many cases, the obtained parameters do not fit accurately the data. In this paper, we extended the study to Mamunya model, with adjustable parameters. Using different carbon black nanocomposites, we obtained a good agreement with the experimental results, but only for concentrations above the percolation critical concentration. Below this point, the fit is not accurate.
