摘　　要：复合材料往往由导体-绝缘体组成,当导电相含量超过临界体积分数,即逾渗阈值时,复合材料有可能出现负介电常数。由于金属陶瓷有其难以避免的局限性,同样能够展现出负介电性能的高分子/碳复合材料便应运而生。该类复合材料在传感器、隐身衣、可穿戴电子设备等方面的应用前景非常广阔。主要介绍了高分子/碳复合负介电材料的分类、性能以及应用研究。Composite materials are often composed of conductor-insulator.When the conductive phasecontent exceeds the critical volume fraction,that is,the percolation threshold,the composite material mayhave a negative dielectric constant.Due to the unavoidable limitations of cermets,polymer/carbon compositematerials that can also exhibit negative dielectric properties have emerged.The application prospects ofsuch composite materials in sensors,stealth clothing,wearable electronic devices,etc.are very broad.Theclassification,performance and application research of polymer/carbon composite negative dielectricmaterials are mainly introduced.
