Study some Electrical Properties of (PS-Tio2-Al2O3) Nanocomposite Films Injected with Air Nanobubbles for Antibacterial Applications

Abstract

From the studied properties, the prepared films were suitable for optical devices and antibacterial application. The electrical properties of (PS-TiO2-Al2O3) nanocomposites films prepared by casting method have studied. To use in Optical applications and electronic devices. The TiO2 and Al2O3 nanoparticles added with different weight percentages are (1, 2, 3 and 4) wt% were injected air bubbles to generate Nano bubbles in the (PS-TiO2-Al2O3) nanocomposites. The dielectric characteristics of films were investigated, and the results revealed that as the concentrations of Al2O3 and TiO2 nanoparticles rises, the dielectric loss, dielectric constant, and a.c electrical conductivity rises. The dielectric loss and dielectric constant decrease with frequency for the applied electric field rises, while electrical conductivity rises.
