Among all the polymers, the polyaniline (PANI) is considered as a promising material due to its easy synthesis, environmental stability and high electrical conductivity on doping. The present study reports the chemical oxidative polymerization preparation of polyaniline and nickel oxide doped polyaniline composite in order to describe the variations in the polyaniline structure, morphology and conductivity upon doping and synthesis condition. The prepared samples were further characterized using -ray diffraction (XRD) and scanning electron microscope to reveal the surface morphology information and formation of crystalline domain embedded in an amorphous matrix within the polyaniline. The temperature dependent DC and frequency dependent AC conductivity of the prepared composites was carried using two probe techniques.
