Frequency and Temperature Dependence of AC Electrical Conductivity of Cadmium Iodide Doped Polyaniline

This paper focuses on investigation of the effect of frequency and temperature on ac electrical conductivity of cadmium iodide doped polyaniline synthesized by simple chemical oxidative polymerization method. The ac electrical conductivities as a function of temperature (308-338 K) and frequency (20 Hz- 1 MHz) was measured. The ac conductivity is temperature dependent and it follows the equation ac = A s. The value of the frequency exponent S was calculated for all the investigated samples. The synthesized material was subjected for structural characterization using FTIR, XRD and SEM.
