Study of Chemically Synthesized Polyindole/Poly(vinyl acetate) Conducting Composite Film

In this study, polyindole/poly(vinyl acetate) (PIN/PVAc) conducting composite film was prepared through chemical polymerization using oxidant FeCl3. As-synthesized sample was characterized by Fourier transform infrared (FTIR), X-ray diffraction (XRD) and DC conductivity measurements. FTIR spectra were supported polymerization of polyindole in presence of poly(vinyl acetate). The polymer chain separation was determined using XRD analysis. An attempt has been made to study temperature dependence of DC conductivity of PIN/PVAc conducting composite film in temperature range 308-393 K. The DC conductivity initially increases and reaches to 3.91 x 10(-7) S/cm.
