A Exploring the Synthesis of Zinc Oxide Nanoparticles Employing Different Techniques and change in Dielectric Constant in Composite (PVC/ZnO-A and PVC/ZnO-B) at Various Temperatures and Concentrations

Abstract

Two sol-gel techniques were used to create zinc oxide (ZnO) nanoparticles: nanoparticles ZnO-A were created by carefully adding a homogeneous solution of sodium hydroxide dropwise into a homogeneous solution of zinc sulphate, whereas nanoparticles ZnO-B were created by abruptly adding a homogeneous solution of sodium hydroxide into a homogeneous solution of zinc sulphate. Heat treatment was used to create powdered zinc oxide, ZnO-A and ZnO-B nanoparticles, which were then analyzed by Dynamic Light Scattering (DLS), and demonstrated that how the enhanced mobility of tiny particles affects the light scattering patterns. The stability of zinc oxide (ZnO-A) nanoparticles was evaluated using sophisticated method such as Nanoparticle Tracking Analysis (NTA) and Zeta Potential studies, which demonstrated its higher stability with a Zeta Potential of 55.98 mV as opposed to ZnO-B nanoparticles having Zeta potential 30.39 mV. The dielectric behavior of the composite (PVC/ZnO-A or PVC/ZnO-B) reveals unique performance traits, impacted by the nanoparticle properties, offering information for applications across a range of technological domains.
