Abstract

This paper describes electrical properties such as electrical conduction characteristics and space charge distributions of polyaniline/polystyrene conducting blends. It is interesting to note that the charging current decreased as the temperature was elevated when DC voltage was applied, and also the hopping distance decreased with the increase of temperature for the PANI/HIPS blends, while generally, the hopping distance decreases as the charging current increases. It is exposed that this result is opposed to widely known phenomenon. It could be examined viewing space charge distributions by a pulsed electroacoustic (PEA) method.
