Polypyrrole Nanoparticles Synthesised for Advanced Optoelectronic Applications: Electrical Characterisation

Abstract

polypyrrole (PPy) nanoparticles were prepared using a low‑temperature oxidative polymerization process,  In this work, the preparation of pure poly pyyrole  and poly pyyrole doped with copper oxide and zinc oxide at different concentrations of each doping agent was studied. The effect of different doping concentrations (Cu2O and ZnO) on thermal stability, conductivity, and morphology was observed through electrical conductivity tests , Hall effect .The electrical conductivity and Hall effect characteristics of pure polypyrrole (PPy) and PPy doped with ZnO and Cu2O nanoparticles made utilizing FeCl₃ and HNO₃ synthesis techniques were examined in this work.
