Progress on improving energy storage performance of polymer dielectrics by constructing trap energy level strategy

本文系统阐述了空间电荷形成机理及空间电荷效应,重点综述了填充无机纳米粒子、掺入小分子半导体和分子结构设计3种构建陷阱能级的方法,深入探讨了提高电介质材料储能性能的设计策略,并对高性能聚合物电介质材料的制备方法进行展望。

In this paper,the space charge formation mechanism and space charge effect were systematically described.Three methods of constructing trap energy levels,including filling inorganic nanoparticles,doping small molecule semiconductors,and molecular structure design,were emphatically reviewed.The design strategy to improve the energy storage performance of the dielectric material were deeply discussed,and the preparation methods of high performance polymer dielectric materials were prospected.
