DC conductivity study of polyaniline and poly(acrylonitrile-butadiene-styrene) blends

In this study, conducting blends of poly(acrylonitrile-butadiene-styrene) and polyaniline doped with dodecylbenzene sulfonic acid were prepared by solution blending. In order to understand the electrical conduction mechanism of the samples, DC electrical conductivity measurements of the blends were carried out in the temperature range of 80–320 K. The experimental results fit well with Mottʹs model of three-dimensional variable range hopping conduction. The values of Mottʹs temperature, density of states at the Fermi energy, average hopping distance and barrier height for the composites were calculated and presented.
