摘要

This study describes the preparation of blends between an amorphous polymer (PVC) and a crystalline polymer (PEO), with a third polymeric part that presents electronic conduction capacity (PEDOT-PSS). Binary (PEO/PVC, PEO/PEDOT-PSS, PVC/PEDOT-PSS) and ternary (PVC/PEO/PEDOT-PSS) blends were prepared by changing the concentrations of the constituents and were analyzed by electronic conductivity, Raman spatial resolution, infrared spectroscopies, and thermogravimetric analysis. The Raman and FTIR analyses showed the incorporation of PEDOT-PSS within the blends. The higher conductivity presented by the ternary blend was 8.6 x 10(-6) Scm(-1), composed of 24% of PVC, 16% of PEO, and 60% of PEDOT-PSS. For binary blends the conductivity was proportional to the PEDOT-PSS content. The thermal stability could be observed through the TG curves of the blends that presented an increase of 19 K in the weight loss temperature at the 10% level when compared to the pure components.
