Abstract
The Y2O3 doped polypyrrole composites has been synthesized (PPy-Y2O3) through an insitu polymerization route, to get dielectric properties for potential applications. XRD confirmed the formation of the composites. SEM confirms the flakier structure in the PPyY2O3. The impedance of pure Y2O3 ~ 14 Ω, PPy ~12 Ω to PPy-10%Y2O3 ~10 Ω compositesdecreased, signify the increase in AC conductivity of PPy-Y2O3. The temperature-dependent dielectric properties follow the Maxwell-Wagner model. AC conductivity of the PPy/Y2O3, increased with an increase in temperature depending on Jonscher’s power law. Therefore, the present study suggested that PPy-Y2O3 composites can be considered useful for device applications.
