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.
