In situ chemical oxidation route has been adopted to prepare polyaniline emeraldine salt (PANI) & magnesium oxide doped Polyaniline (MgO/PANI) with different molar concentration of MgO using ammonium dichromate (NH4)2Cr2O7 (ADC) as an oxidant & HCL as catalyst. Composite of PANI with 5%, 10%, 20 %, 30%, 40% & 50% of magnesium oxide (MgO) has been synthesized by adding magnesium oxide powder gradually in the polymerization solution of aniline & APS. Further these composites were characterized by XRD & SEM techniques to investigate their structural and morphological studies. As a part of electrical studies, AC conductivity, dielectric constant, dielectric loss and variation of tanδ of all the composites were studied as a function of frequency by using impedance analyser. DC conductivity was studied as a function of temperature.
