Abstract

Physical properties and thermal behaviours of polymers vary by molecular weight or stereoisomers. These properties also change in the presence of polymeric and nonpolymeric additives. Conductive polymers are insoluble in original organic solvents and their processibility are limited. In this research, the processible conducting polymers are synthesized and their electrical properties and thermal behaviour are studied. The blends of polyvinyl acetate (PVAc), polystyrene (PS) and polyvinyl chloride (PVC) with polypyrrole (PPy) and polyaniline (PANi) are prepared. On the other hand, the percentages of compounds of these blends for suitable electrical properties, solubility and processability are optimized. All the samples were prepared in the smooth form and thin film. A four-point probe method is adopted to examine the electrical DC conductivity. It is found that the conductivity of the blends is decreased but their processibility and solubility are increased. Thermal stability of polypyrrole and polyaniline blends were investigated by SCANNING THERMAL ANALYSIS (STA), DIFFERENTIAL SCANNING CALORIMETRY (DSC) and thermal gravimetrical analysis (TGA). As it is evident from the results, the prepared blends are much more stable compared with polypyrrole, polyaniline and host polymers.
