The combination of polyaniline and metal oxide composites with uniform distribution is expected to facilitate wider applications of the material. In this study, Polyaniline (PANI) and Silver oxide doped polyaniline (AgO/PANI) with different molar concentration were prepared by chemical oxidation route using ammonium dichromate (NH4)2Cr2O7 (ADC) as oxidant and HCL as catalyst. The structural and surface morphology of the nanocomposites were characterized by XRD & SEM technique. The electrical properties (AC & DC) and dielectric properties were determined using impedance analyser. The AC conductivity, dielectric constant, dielectric loss and variation of tanδ of all the composites were studied as a function of frequency at room temperature and DC conductivity were analysed as function of temperature.
