Abstract

Fractional-order capacitor (FOC) is fabricated. The dielectric of the FOC is synthesized using Graphene nanosheets (GNS) as fillers in a P(VDF) matrix. A variety of weight percentages of GNS have been employed in a total of five samples fabricated. Fractional-order behavior is observed for samples having more than 3 wt% loading of GNS in P(VDF) matrix. Nyquist and Bode plots have been provided for the samples. It has been shown that non-ideality is induced with addition of conductive material in P(VDF). FOC characteristics are evident in all the samples with maximum deviation occurring for sample with 9 wt% GNS. Beyond 13 wt% of GNS, conductivity attains constant value. This type of analysis is novel in nature and is a guide to analyze percolated polymer composites.

基于石墨烯纳米片/P(VDF)复合材料的新型单组分分数级电容器:合成与分析

制备了分数阶电容器(FOC)。采用石墨烯纳米片(GNS)作为P(VDF)基体的填料，合成了FOC的介电材料。在总共制备的五个样品中使用了不同的GNS重量百分比。分数阶行为在P(VDF)矩阵中含有超过3wt %的GNS的样品中被观察到。已经为样本提供了奈奎斯特和博德图。结果表明，在P(VDF)中加入导电材料会引起非理想性。FOC特征在所有样品中都很明显，最大偏差发生在GNS为9 wt%的样品中。超过GNS的13wt %，电导率达到恒定值。这种类型的分析在本质上是新颖的，是分析渗透聚合物复合材料的指南。
