Anomalous electrical behaviour of polymer-carbon composites as a function of temperature

Abstract

In the field of electromagnetic interference, there has been great interest in finding a lightweight and conductive shielding material. In this composite study, several carbon blacks and PAN carbon fibres were added to amorphous (polystyrene) and crystalline (polyethylene) polymer matrices. This effort sought to examine the electrical conduction mechanisms and the effects of temperature and processing conditions on the electrical conductivity of polymer-carbon composites. To this end, conductivity experiments were conducted in isothermal, cycled, and annealing temperature conditions.
