【摘要】：高储能密度聚合物基复合电介质材料在电容器领域具有很高的应用价值,目前很多研究集中在本身具有较高的介电常数的铁电材料上。通过探讨铁电聚合物基纳米复合电介质材料储能理论、电极化特性、充放电效率等与储能密度密切相关的性能,深入分析了复合电介质材料的储能机理并提出了下一步的发展方向。并进一步讨论了目前铁电聚合物基复合电介质材料的主要制备策略,包括纳米填料表面修饰改性、多相共混复合和多层结构调控以及由此实现的介电性能和储能密度的提升。
[Abstract]:Polymer-based composite dielectric materials with high energy storage density have high application value in the field of capacitors. At present, many studies focus on ferroelectric materials with high dielectric constant. The energy storage theory, polarization characteristics and charge-discharge efficiency of ferroelectric polymer based nanocomposite dielectric materials are discussed, which are closely related to the energy storage density. The energy storage mechanism of composite dielectric materials is deeply analyzed and the development direction of the next step is put forward. The main preparation strategies of ferroelectric polymer based composite dielectric materials are further discussed, including surface modification of nano-fillers, multiphase blending composite and multi-layer structure control, as well as the improvement of dielectric properties and energy storage density.
