聚合物纳米复合材料只要制备和制备得当，就具有良好的工程性能。最近在介电材料和电绝缘等聚合物纳米复合材料方面做了一些工作。2004年，根据截至2003年发表的文献，对此进行了回顾。自那以后，又有了新的重大发现。此外，从有限厚度界面电化学结构的细观分析出发，提出了一个与“相互作用区”密切相关的具有远距效应的多核模型。文中推测性地考察了该模型如何适用于纳米复合材料中已发现的各种特性和现象，如电学特性、耐高压环境和热学特性。
Polymer nanocomposites possess promising high performances as engineering materials, if they are prepared and fabricated properly. Some work has been recently done on such polymer nanocomposites as dielectrics, and electrical insulation. This was reviewed in 2004 based on the literatures published up to 2003. New significant findings have been added since then. Furthermore, a multi-core model with the far-distance effect, which is closely related to an "interaction zones", has been proposed from consideration of mesoscopic analysis of electrical and chemical structures of an existing interface with finite thickness. It is speculatively examined in the paper how the model works for various properties and phenomena already found in nanocomposites as dielectrics focusing on electrical characteristics, resistance to high voltage environment, and thermal properties.
