摘　　要：聚合物纳米复合材料能够发挥纳米材料在电、磁、光等方面的优越性,也具有聚合物的易成型等方面的优点,正成为电介质领域研究的热点。本文综述了聚合物纳米复合材料在介电性能方面的研究概况,主要涉及了电导、介电强度与空间电荷、介电常数、介电损耗以及局部放电等方面的研究。最后展望了今后的研究方向。Polymer nanocomposites not only exhibit advantageous electrical, magnetic, optical properties of nanomaterials but also have the advantage of easy molding of polymer and therefore great attentions are now paid to the research of them. This paper summarizes the recent advances of the researches on the dielectric properties of the polymer nanocomposites, and especially deals with the investigation results concerning the electrical conduction, dielectric strength, space charge, dielectric permittivity, dielectric loss and partial discharge. The aspect of the future research work is proposed.
