Abstract

In this contribution we extend our previous studies on polyaniline blends to the study of some physical properties of different polyaniline polyvinylchloride (PANI-PVC) blends. Previous data on polyaniline-polyethylene (PANI-PE) blends have revealed a rapid drop of the mechanical features of the blend, as the concentration of polyaniline (PANI) is increased and a relatively slow increase in the electrical conductivity. As the blend has been prepared by mechanical mixing of components, the electrical conductivity decreases in time, probably due to a stabilisation of the blend towards oxygen accompanied by the transformation of the conducting polyaniline (emeraldine salt) into the insulating form of the polyaniline
