The synthesis of polymer-grafted nanoparticles (PGNPs) or hairy nanoparticles (HNPs) by tethering of polymer chains to the surface of nanoparticles is an important technique to obtain nanostructured hybrid materials that have been widely used in the formulation of advanced polymer nanocomposites. Ceramic-based polymer nanocomposites integrate key attributes of polymer and ceramic nanomaterial to improve the dielectric properties such as breakdown strength, energy density and dielectric loss. This review describes the "grafting from" and "grafting to" approaches commonly adopted to graft polymer chains on NPs pertaining to nano-dielectrics. The article also covers various surface initiated controlled radical polymerization techniques, along with templated approaches for grafting of polymer chains onto SiO, TiO, BaTiO, and AlO nanomaterials. As a look towards applications, an outlook on high-performance polymer nanocomposite capacitors for the design of high energy density pulsed power thin-film capacitors is also presented.
通过将聚合物链连接到纳米颗粒表面来合成聚合物接枝纳米颗粒（PGNP）或毛发状纳米颗粒（HNP）是获得纳米结构杂化材料的一项重要技术，这些材料已广泛用于先进聚合物纳米复合材料的配方中。陶瓷基聚合物纳米复合材料整合了聚合物和陶瓷纳米材料的关键属性，以改善诸如击穿强度、能量密度和介电损耗等介电性能。本综述描述了在与纳米电介质相关的纳米颗粒上接枝聚合物链时常用的“从……接枝”和“接枝到……”方法。本文还涵盖了各种表面引发的可控自由基聚合技术，以及将聚合物链接枝到SiO、TiO、BaTiO和AlO纳米材料上的模板法。展望应用方面，还介绍了用于设计高能量密度脉冲功率薄膜电容器的高性能聚合物纳米复合电容器的前景。
