Abstract The physico-chemical properties of polymer ceramic composites highly depend upon the nature of ceramic, polymer and their interface. Among other interesting features, they have potential for flexible electronics and energy storage devices. Especially, graphene based polymer ceramic composites are unique for their high dielectric characteristics. In this regard, we synthesized a three constituent novel nanocomposite with polymer matrix to check their potential for energy storage applications. Here in, the polypyrrole has been exquisitely decorated with graphene oxide and manganese ferrite nanoparticles with their different concentrations. The development of spherical grains and their transformation into rod like morphology with a significant change in their dimension is noticed. The weight percentage of all elements according to their stoichiometric formula and the finger prints of different constituents in the form of their functional groups are also identified before their dielectric and ferroelectric analyses. The highest value of dielectric constant (121449) has been noticed at 100 Hz frequency, which reduced to 1066 at 1 MHz. The dielectric loss was also quite high at lower frequency which decreased to 1.2 at same high value of frequency (1 MHz). The calculations for recoverable energy density and energy loss density are performed using PE hysteresis loops and the highest value of recoverable energy density is recorded as 4.7 × 10−8 mJ/cm3. Thus, high values of dielectric constant and low dielectric loss of these nanocomposites make them attractive dielectric material in electrical appliances for capacitive applications.

确定 GO/MnFe2O4/PPy 纳米复合材料中电荷载流子短程和长程迁移率的频率范围

摘要 聚合物陶瓷复合材料的理化性能很大程度上取决于陶瓷、聚合物及其界面的性质。除了其他有趣的功能外，它们还具有用于柔性电子和储能设备的潜力。特别是，石墨烯基聚合物陶瓷复合材料因其高介电特性而独树一帜。在这方面，我们合成了一种具有聚合物基质的三组分新型纳米复合材料，以检查它们在储能应用中的潜力。在这里，聚吡咯用不同浓度的氧化石墨烯和锰铁氧体纳米颗粒进行了精美的装饰。注意到球形晶粒的发展及其向棒状形态的转变，其尺寸发生显着变化。在进行介电和铁电分析之前，还可以根据化学计量公式确定所有元素的重量百分比以及以官能团形式存在的不同成分的指纹。介电常数的最高值 (121449) 在 100 Hz 频率下被注意到，在 1 MHz 下降至 1066。较低频率下的介电损耗也相当高，在相同的高频率值 (1 MHz) 下降至 1.2。可恢复能量密度和能量损失密度的计算是使用 PE 磁滞回线进行的，可恢复能量密度的最高值记录为 4.7 × 10−8 mJ/cm3。因此，
