摘要: Nanodielectrics based on metal oxide nanoparticles (NPs) exhibit significant improvement in dielectric performances. This study was carried out to examine the properties of Poly vinyl chloride (PVC) with introduction zinc (ZnO) NPs synthesized by simple sol gel method. The microstructure and surface morphology ZnO were characterized X-ray diffraction (XRD) field emission scanning microscopy (FE-SEM). formation wurtzite-type verified from XRD average crystallite sizes around 35 nm. PVC/ZnO-NPs nanocomposites prepared solution-cast technique two different procedures addition. PVC/ZnO studied measuring DC strength constant 1 kV/s ramp response as function frequency 500 Hz 1 MHz. A enhancement breakdown has been observed addition NPs. values reached up 45 % (for PVC/0.14 vol% ZnO) more than obtained for pristine PVC sample. effect dispersibility due used confirmed FE-SEM. dependency real part permittivity (e ′) filler concentration results strength.
