| Abstract: | BaTiO3/PVDF composites films, with PVDF as matrix, nanometer sized BaTiO3 as fillers, were prepared by a simple mix and casting process. The microstructure of the BaTiO3/PVDF composites were examined by SEM, the dielectric properties of samples were discussed. BaTiO3/PVDF composites (film size: 70 mm×3 mm×25 μm，electrode area: 600 mm2) were applied in film capacitors, and the key parameters of capacitor include capacitance, loss, thermal stability and breakdown voltage were tested. The results show that the BaTiO3/PVDF film capacitors have good thermal stability below 100℃ and high breakdown voltage(1.3 kV), capacitance can reach 3.4nF, while the loss is below 0.03, which demonstrate that the good application of BaTiO3/PVDF composites in film capacitor industry. |
