Research output: Contribution to journalArticlepeer-review


Blends of plasticized polystyrene and conductive polyaniline (PANI) were prepared by melt processing, and extruded filaments were obtained by using a capillary rheometer. The effect of flow conditions, including temperature and shear rate, on the morphology of the blends and on the resulting electrical conductivity were investigated. Under a combination of specific processing and given blend compositions, the electrical conductivity was found to be independent of shear level over a wide range of shear rates. Thus, conductive melt processible PANI-based blends can be designed, however relatively high PANI concentrations (well above percolation) are required. Blend systems can be developed to further reduce the PANI concentration in ternary component blends.
