Frequency Dependent Conductivity and Dielectric Behavior Studies of Cu Doped Polyindole in Presence of Poly(Vinyl Acetate)

In this article we present results of frequency dependent conductivity and dielectric behavior investigation of Cu doped polyindole in presence of poly(vinyl acetate). As-synthesized composites were analyzed via X-ray diffractometer, fourier transform infrared spectra spectrum, dielectric behavior and ac conductivity measurements. The Cu doped PIN/PVAc composites represent semi-crystalline nature confirmed through X-ray diffraction analysis. The dielectric behavior study of prepared composites reveals that dielectric constants and dielectric loss decreases with increase in frequency. The highest ac conductivity value of composites was estimated as 2.97 x 10(-5) S/cm at frequency 1 MHz.
