中文摘要：

电力设备及电子器件的发展需要高性能的绝缘与功能电介质作为支撑，高储能密度聚合物绝缘材料、导热绝缘聚合物绝缘材料以及非交联型高压交／直流电缆绝缘材料等是近期绝缘与功能电介质材料领域的研究热点，本文对上述三个研究热点在国内外的主要研究进展进行了综述，并展望了未来的发展方向。

英文摘要：

The development of electric equipment and electrical devices requires high performance insulat- ing and dielectric materials. At present, dielectric polymer materials with high electrical energy density, thermally conductive and electrical insulating materials, and non crosslinked insulating materials for high voltage or DC cable are three hot topics in the field of electrical insulating and dielectric polymer materi- als. The research progress of these three hot topics at home and abroad was reviewed in this paper, and the further development direction on these materials was proposed.
