NiO Nanoparticles (NNP) were synthesized by a self propagating high temperature synthesis from nickel nitrate. Synthesized NiO are used to prepare Polyaniline (PANI)-NiO nanocomposites by in situ chemical oxidative polymerization at 0–50C. Different weight percentages of NiO (10%, 20%, 30% and 40%) were added during the polymerization. The nanocomposites were characterized by X-Ray diffraction (XRD) and Fourier Transform Infrared (FTIR) and UV Techniques. Crystallite strain is calculated from Williamson-Hall(WH) method using XRD data. Surface morphology was studied using Scanning Electron Microscopy (SEM) and EDAX. Frequency dependent AC conductivity and dielectric properties of PANI-NNP composites were analyzed in the frequency range 50–106 Hz at room temperature. These nanocomposites have microwave, sensor and battery applications.
