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.

PPY/Y2O3 复合材料随温度变化的介电特性

通过原位聚合路线合成了掺杂 Y2O3 的聚吡咯复合材料（PPy-Y2O3），以获得潜在应用的介电性能。XRD 证实了复合材料的形成。扫描电镜证实 PPyY2O3 具有更薄的结构。从纯 Y2O3 ~ 14 Ω、PPy ~ 12 Ω 到 PPy-10%Y2O3 ~ 10 Ω 复合材料的阻抗降低，表明 PPy-Y2O3 的交流导电率增加。随温度变化的介电性能遵循 Maxwell-Wagner 模型。PPy/Y2O3 的交流电导率随着温度的升高而增加，这与 Jonscher 的幂律有关。因此，本研究认为 PPy-Y2O3 复合材料可用于器件应用。
