Effect of ZnO particles on structural, morphological electrical and dielectric properties of polyaniline

Abstract

In situ chemical oxidation route has been adopted to prepare polyaniline emeraldine salt (PANI) & zinc oxide doped Polyaniline (ZnO/PANI) with different additive weight percent of ZnO using ammonium persulfate (NH4)2S2O8 as an oxidant & HCL as catalyst. Composite of PANI with 10%, 20%, 30%, 40% & 50% of zinc oxide (ZnO) has been synthesized by adding zinc 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 of all the composites were studied as a function of frequency by using impedance analyser. DC conductivity was studied as a function of temperature.
