The composite films were synthesized with various weight percentages of pyrrole, and characterized by FT-IR spectroscopy, conductivity measurement. The FT-IR result shows the successful incorporation of PEG into the PPy structure forming PPy-PEG composite films. The dc electrical conductivity of the films, at 318K, first increases with wt% of pyrrole and attains the maximum value (& Copyright@ International Science Community Association 963; = 2.55 X 10-8 S/cm) at 40 wt% of pyrrole. However further increase in wt% of pyrrole decreases the conductivity of the films. Temperature dependence of dc electrical conductivity showed that PPy-PEO composites with different pyrrole wt% samples follow Arrhenius law. The linear nature was observed because of charge carriers created and their increased mobility.
