Polymer nanocomposites as dielectrics have attracted a wide range of research interests due to their improved performance. One of the observed characteristics of polymer nanocomposites is the suppression on space charge injection and accumulation and the charge transport mechanism behind is also investigated based on thermally activated hopping (TAH) and quantum mechanical tunnelling (QMT) mechanisms. However, there still lacks research on the effect of moisture on charge transport characteristics and its relationship with experimental results. We herein proposed a method to re-virtualize the distribution of nanoparticles/their aggregates based on the multidimensional scaling method in the first step, and a simple numerical method is further following to estimate the contribution of TAH and QMT conductivities to the experimental ones. The results, firstly, indicate the presence of moisture could lead to significant charge injections, and for different relative humidity condition...

水分对聚合物纳米复合物中电荷迁移的影响的实验研究和数值估计

聚合物纳米复合材料作为电介质由于其性能的提高而引起了广泛的研究兴趣。聚合物纳米复合材料的观察到的特性之一是抑制空间电荷的注入和积累,并且还基于热活化跳跃(TAH)和量子力学隧穿(QMT)机理研究了背后的电荷传输机理。但是,仍然缺乏关于水分对电荷传输特性的影响及其与实验结果的关系的研究。在第一步中,我们基于多维缩放方法提出了一种重新虚拟化纳米颗粒/聚集体分布的方法,随后采用了一种简单的数值方法来估算TAH和QMT电导率对实验电导率的贡献。结果,
