【摘要】：高儲(chǔ)能密度聚合物基復(fù)合電介質(zhì)材料在電容器領(lǐng)域具有很高的應(yīng)用價(jià)值,目前很多研究集中在本身具有較高的介電常數(shù)的鐵電材料上。通過(guò)探討鐵電聚合物基納米復(fù)合電介質(zhì)材料儲(chǔ)能理論、電極化特性、充放電效率等與儲(chǔ)能密度密切相關(guān)的性能,深入分析了復(fù)合電介質(zhì)材料的儲(chǔ)能機(jī)理并提出了下一步的發(fā)展方向。并進(jìn)一步討論了目前鐵電聚合物基復(fù)合電介質(zhì)材料的主要制備策略,包括納米填料表面修飾改性、多相共混復(fù)合和多層結(jié)構(gòu)調(diào)控以及由此實(shí)現(xiàn)的介電性能和儲(chǔ)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.
