摘要
新型高储能密度聚合物基绝缘材料由于应用潜力巨大,在近些年来发展速度很快。本文简单介绍该材料的重要性,解释电介质材料的储能机理、介电常数、电位移、击穿场强与储能密度之间的关系,以及计算储能密度和充放电效率的方法,然后分别对聚合物电介质和复合电介质材料研究进展进行概述,重点讨论材料的制备策略、加工工艺、微观/宏观机理分析和性能表征,并在文章最后对高储能密度聚合物基绝缘材料进行总结和展望。
Due to the huge potential of application,the advanced polymer-based insulating materials with high energy storage density have developed fast in the recent years.This paper briefly introduced the importance of these materials,and explained the mechanism of energy storage for dielectrics.The connections between energy density and the properties of these materials were also introduced,such as dielectric permittivity,electric displacement and breakdown strength.The ways to calculate energy density and charge-discharge efficiency were discussed too.Then the recent research developments of dielectric polymers and the dielectric nanocomposites were summarized respectively,focusing on the strategies of fabrication,processing procedure,the microcosmic and macroscopic mechanism analyses and the characterization of materials.Finally,the progress and future perspectives of the polymer-based insulating materials with high energy density were summarized.
