| Abstract | ||
| Applying the green method in this study to synthesize the nanoparticles of zinc oxide (ZnO NPs) from reacting pomegranate peel extract with aqueous zinc nitrate in an environmentally friendly aqueous solution. The ZnO nanoparticles were characterized using various techniques: FTIR, XRD, EDX, and SEM. The results showed that the prepared particles had high purity and their sizes ranged from 24 to 44 nm, which confirmed the successful synthesis and purity of the composite produced. In order to study the electrical properties of the resulting film, the ZnO nanoparticles were embedded in polymethyl methacrylate (PMMA). Both dielectric constants, the real and the imaginary, recorded the highest values when frequencies were low and then began to gradually decrease with increasing frequency. In contrast, when the frequency is at its lowest value, the conductivity is at its lowest value but increases gradually with the frequency increase. | ||
