In the present work we report the development of PANI/NiO composites with varying NiO content by in situ polymerization technique. The developed composites were subjected to morphological characterization by scanning electron microscope and structural characterization by X-ray diffraction technique. The AC conductivity and dielectric constant of composites were studied as a function of frequency. All the composites displayed increase in conductivity and dielectric constant with the increase in NiO content. Uniform dispersion of NiO and increase in number of interfaces was attributed to increase in conductivity and dielectric constant of composites respectively.
