聚合物纳米复合材料被定义为其中少量纳米尺寸填料仅以几个重量百分比均匀分散的聚合物。仅添加几个重量百分比的纳米填料即可对聚合物的物理、化学、机械和电性能产生深远的影响。这种改变通常有利于工程目的。这种纳米复合材料技术已经从工程塑料领域兴起，并有可能将其应用扩展到结构材料、涂料和医疗/生物医学产品以及电子和光子设备的包装。近年来，这些具有优异性能的“高科技”材料开始吸引介电和电绝缘领域的研究人员。由于纳米填料与聚合物基质的相互作用会带来新的性能，因此预计会出现介观性能，这对科学家和工程师来说都是很有趣的。预计电介质和电绝缘体的特性将得到改善。一些有趣的结果表明了可预见的未来，其中一些在论文中描述了材料和加工以及基本概念和未来方向。
Polymer nanocomposites are defined as polymers in which small amounts of nanometer size fillers are homogeneously dispersed by only several weight percentages. Addition of just a few weight percent of the nano-fillers has profound impact on the physical, chemical, mechanical and electrical properties of polymers. Such change is often favorable for engineering purpose. This nanocomposite technology has emerged from the field of engineering plastics, and potentially expanded its application to structural materials, coatings, and packaging to medical/biomedical products, and electronic and photonic devices. Recently these 'hi-tech' materials with excellent properties have begun to attract research people in the field of dielectrics and electrical insulation. Since new properties are brought about from the interactions of nanofillers with polymer matrices, mesoscopic properties are expected to come out, which would be interesting to both scientists and engineers. Improved characteristics are expected as dielectrics and electrical insulation. Several interesting results to indicate foreseeable future have been revealed, some of which are described on materials and processing in the paper together with basic concepts and future direction.
