This study involved the preparation of novel ternary PANI/rGO-Cr2O3, PANI/rGO-NiO, PANI/NiO-Cr2O3 nanocompsites using in-situ polymerization method. The resulting nanocomposites were identified using FT-IR, XRD, and FESEM measurements. The electrical properties of single PVA polymer films and PVA hybrids were studied by LCR techniques at frequency range of 1kHz -5kHz and a temperature of 25 οC. The measurements of electrical conductivity exhibited an augmentation in the magnitudes of the dielectric constant (ɛ’) and the dielectric loss factor (ε′′). The value decreases as the frequency increases. The thermal measurements showed that the thermal conductivity coefficient decreases with increasing the frequencies.
