高介电常数的柔性复合材料长期以来一直是提高嵌入式电容器性能所期望的。提高柔性聚合物介电常数最有前景的方法之一是添加具有特定纳米结构的填料。先前的报道显示，含有10 wt%定向排列的钛酸钡颗粒的纳米复合材料在厚度方向上的介电常数显著提高。在此，一种实现超低石墨烯添加量的简便策略（
High dielectric permittivity flexible composites have long been desired for enhancing the performance of embedded capacitors. One of the most promising approaches to improve the dielectric permittivity of flexible polymer is the addition of fillers with specific nanostructures. Previous reports revealed that nanocomposites with aligned 10 wt% barium titanate particles showed substantially enhanced dielectric permittivity in the thickness direction. Herein, one facile strategy toward ultralow addition of graphene (
