具有优异加工性和高击穿强度（E-b）的聚合物电容器可用于开发高能量密度电容器。虽然通过添加高含量（>10体积%）的高K无机填料已经实现了聚合物电介质的介电常数（K）的改善，但是这种方法在可扩展的膜加工中面临重大挑战。在这里，超低比率的并入（
Polymer dielectrics with excellent processability and high breakdown strength (E-b) enable the development of high-energy-density capacitors. Although the improvement of dielectric constant (K) of polymer dielectric has been realized by adding high-K inorganic fillers with high contents (>10 vol%), this approach faces significant challenges in scalable film processing. Here, the incorporation of ultralow ratios (
