Defect-modified copolymer P (VDF-CTFE) has a high dipole density and breakdown field, and BaTiO3 (BT) has a high dielectric constants. Both their characteristics can be achieved in P(VDF-CTFE)/BT composites. The powders of BaTiO3 was manufactured by sol-gel methods and coupled in KH550. The composites which is compounded from P(VDF-CTFE) and BT exhibit high breakdown field(300 MV/m), high electric displacement(D 0.15 C/m2) and low dielectric loss. The results indicate that these composites are the potential materials for high energy density capacitors.
