摘　　要：高储能密度电介质材料是电容器储能器件的核心,对高能武器和智能电网等先进装备领域有着非常重要的影响,近年来受到了广泛关注.相较于金属氧化物和陶瓷类介电材料,聚合物基介电材料具有密度低、易成型、损耗低、击穿强度高等优点.本文结合该领域发展现状,对聚合物基介电复合材料的设计、制备及相关性能研究进行了综述,并对其未来发展进行了展望.Dielectric materials with high energy storage density were the core of the energy-storage capacitor, which had a very important influence on advanced equipment fields such as high-energy weapons and smart power grids. Compared with metal oxide- and ceramic-based dielectric materials, polymer-based ones possessed the advantages of low density, good processability, low loss, and high breakdown strength. Herein, the design, preparation and related properties of polymer- based dielectric composites were reviewed.
