Abstract In the present work we report the synthesis of PANI-Fe2O3 composites by in situ polymerization technique. The Fe2O3 content in the composites was varied from 10 to 50 wt%. Morphological and structural characterization of the as synthesized composites was carried out using scanning electron microscope and X-ray diffraction technique. The AC conductivity and dielectric constant of composites were studied as a function of frequency. With the increase in Fe2O3 content in composites from 10% to 50% the conductivity is found to increase at higher frequencies. The dielectric constant measurements showed that with the increase in Fe2O3 concentration the dielectric constant was found to be increasing and was highest for composite with 50% Fe2O3 content.
