Electrical and mechanical properties of conducting polymer composites

The method of chemically initiated oxidative modification of polypropylene particles in suspension by pyrrole was used for preparation of conductive polypropylene/polypyrrole composites. Their properties were compared with either polypropylene/polypyrrole composites prepared by melt mixing of virgin polypropylene with chemically synthesized polypyrrole or with polypropylene/carbon black composites prepared also by melt mixing. The composites were characterized by elemental analysis and by mechanical testing. The influence of the processing conditions on the properties of composites is shown. The antistatic properties of prepared composites were demonstrated.
