ABSTRACT Polyaniline pure and doped in ferro fluid was prepared in different concentration at room temperatuer. The ac electrical properties were stadied.AC conductivity,σac(ω), is found to vary as ωs in the frequency range(50Hz-15MH),s < 1and increases with the increase of ferro fluid indicating adominat hopping process. The conductivity increased two order with increasing the concentration of ferro fluid, and one order with frequency. The dielectric constant ε1and dielectric loss ε2 have been determined for bulk polyaniline. Both ε1 and ε2 decreases with increasing frequency.
