▎ 摘　　要

The poly(vinylidene fluoride)-based hybrid composites with a blended BaTiO3-exfoliated graphene as filler were fabricated with the efficient method of solution casting and hot pressing and their dielectric properties were investigated in detail. In advance, both of the nanoparticles are functionalized to improve the interfacial bonding between fillers and matrix. Synergistic effects arising from blending zero-dimensional BaTiO3 and two-dimensional exfoliated grapheneare identified by the improved distribution of nanoparticles in poly(vinylidene fluoride) host and mitigating the concomitant increase in dielectric loss while maintaining the high dielectric constant values of the composites.
