| Abstract | ||
| Polyaniline (PANI) has been prepared by the oxidation method in order to fabricate it with various concentrations of copper nanoparticles (CuNPs) which produced using the reduction method. Various techniques have characterized pure PANI and PANI doped CuNPs composites, such as fourier transform infrared spectroscopy (FT-IR), X-ray diffraction spectroscopy (XRD), field emission scanning electron microscopy (FE-SEM) and energy dispersive X-ray spectroscopy (EDS), which were provided important information about the structure and morphology of the fabricated polymer nanocomposites. The properties of dielectric permittivity (έ), dielectric loss (ἔ) and electrical conductivity (σ_AC) properties were studied at room temperature versus a range of frequency (15-150) kHz. The results demonstrated that the addition of copper nanoparticles to polyaniline matrix increases the dielectric permittivity property and it decreases with increasing the frequency to reach a fixed value. So, the electrical conductivity of studied samples decrease with increasing the frequency. | ||
