Synthesis of ZnO Nanoparticles and Electrodeposition of Polypyrrole/ZnO Nanocomposite Film

Zinc oxide nanoparticles (ZnO NPs) were synthesized by simple and efficient method in aqueous media from zinc nitrate without any requirement of calcinations step at high temperature. The ZnO NPs are studied by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Then, a hybrid material of polypyrrole (PPy)/ZnO NPs were synthesized with electropolymerization of pyrrole in an aqueous media within dispersed ZnO NPs. The particulars of PPy growth properties have been considered by continuous voltammograms. PPy and PPy/ZnO NPs microscopic images were obtained by SEM and atomic force microscopy (AFM) techniques.
