Low dielectric properties of BaTiO3/PVDF composites limit its application in modern microelectronics and high energy storage. In this work, three-phase composites with high dielectric properties were prepared based on the surface modification of BaTiO3(BT) ceramic. The results show that, after modification of BT, the dielectric constant of the BT/PVDF composite increased by 44%, and the dielectric loss decreased by 20% at 100Hz. Nickel powder was added to the modified composites for increasing dielectric constant, when the addition of nickel powder was 20%, the dielectric constant of composites was up to 441 and the dielectric loss of composite was only 0.057.
