摘要：
Composite films of polyaniline and synthetic rubber (cis-1,4-polyisoprene) were studied to understand the charge transport under pressure and temperature. Films of different compositions were prepared to measure current-voltage curves across the film thickness. The results reveal that these materials exhibit electrical conductivity as predicted by the classical theory of percolation. This has been discussed in the light of microscopic interaction between rubber and polyaniline aggregates. Pressure dependent electrical conductivity of these composites can be best explored to develop low cost pressure sensing materials. (c) 2008 Elsevier Ltd. All rights reserved.
