摘要：

A four probe method was used to measure the electrical conductivities of poly(styrene-co-acrylonitrile)/expanded graphite composites. The composites showed excellent electrical conductivities in both a- and c-axes. The different effects of temperature and the applied current on the conductivities in a-axis and in c-axis were observed. It was found that the conductive behaviors of the composite were different from those of semiconductor and carbon black loaded polymer composites. All these differences and excellent conductivity were considered to be related to the structure of the composites. (c) 2005 Elsevier Ltd. All rights reserved.
