Full Article:

The present paper is concerned with heterogeneous materials in which the mor-phology is specifically designed to achieve functional properties. These materials, or mate-rial systems, are found in energy systems such as fuel cells and batteries, but also in aeronau-tical structures such as the conductive skins of commercial airplanes which have polymer composite primary structures. Many of these heterogeneous materials are dielectric and, under certain conditions, conductive. Charge transport and storage in such materials is typi-cally discussed in terms of equivalent (electrical) circuits, without recourse to first principles physics or mechanics. The present paper discusses the transport and storage properties of several examples of such materials from a computational standpoint, and compares some critical predictions with experimental data. Opportunities and needs for improving our un-derstandings and computational capabilities for this class of problems will also be discussed.
