Abstract

The dispersion of nanomaterials such as graphene has a major influence on the electrical conductivity in nanocomposites with a polymer matrix. For the description of this effect a continuum model is presented. Within this model, the percolation threshold is determined. Moreover, a distributional analysis is used for the purpose of taking electron hopping between graphene into account. Hence, interfacial conductivity enhanced by tunneling is also included in this study. Recent measurements of nanocomposites that are used for aerospace applications are compared with the results of the presented model and show good agreement between model and experiment.
