摘　　要：通过柠檬酸盐法合成超细锆钛酸钡(BZT)粉体,采用涂刷法制备BZT/PVDF(聚偏四氟乙烯)复合体系电介质厚膜,研究了不同BZT含量的电介质厚膜样品的结构与储能性能。结果表明,经过表面改性的陶瓷粉体,与聚合物PVDF混合均匀。在不同BZT含量样品中,27%BZT/PVDF复合电介质厚膜具有优异储能性能,储能密度为0.4 J/cm^(3),储能效率为65%。In this work,superfine BZT powders were synthesized by the citrate method.BZT/PVDF dielectric composite thick films were prepared by coating method.The structure and energy storage performance were investigated on the samples with different BZT contents.The results indicated that BZT powders could uniformly disperse in the PVDF matrix after surface modification.Among the investigated samples,27% BZT/PVDF displayed excellent energy storage properties.The sample showed an energy storage density of 0.4 J/cm^(3) and energy efficiency of 65%.
