The Y2O3 doped polypyrrole composites has been synthesized (PPy-Y2O3) through an in- situ polymerization route, to get dielectric properties for potential applications. XRD confirmed the formation of the composites. SEM confirms the flakier structure in the PPy- Y2O3. 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.
