Conducting polyaniline/nickel ferrite (PANI/NiFe₂O₄) composites are synthesized by employing interfacial polymerization method. The composite has been synthesized with 10, 30 and 50 wt.% of nickel ferrites in PANI. The prepared samples were characterized by FTIR and SEM with EDS. The dominant peaks in FTIR graph confirm the formation of PANI/NiFe₂O₄ composites. The XRD pattern, confirms the formation of composites. The surface morphology of these composites was studied with scanning electron microscope (SEM). Impedance and electric modulus of these composites was investigated in the frequency range of 10² Hz to 10⁶ Hz. It is found that Debye type relaxation has been confirmed by the Cole-Cole plot and electrical modulus is inversely proportional to the conductivity of these composites.
