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 (
