采用流延工艺，在ITO玻璃衬底上制备了不同质量分数的锆钛酸铅（PZT）／聚偏氟乙烯（PVDF）热释电复合材料。采用X射线衍射方法对复合材料极化前后的物相变化进行了对比分析，通过扫描电子显微镜分析了不同PZT质量分数复合材料的界面特征。从热释电探测器件的实际要求出发，利用介电阻抗测试仪、动态法热释电系数测试系统等仪器系统地测试了复合材料体系中PZT含量对材料热释电性能和介电性能的影响。结果显示，在PZT质量分数为50％时，制得了热释电系数p为4．1nC／（cm2·K）的性能优良的热释电复合材料。

Thick films of composites of lead-zirconate-titanate （PZT） particulate and polyvinylidene fluoride （PVDF） copolymer have been produced by casting on the indium-tin-oxide （ITO）-coated glass substrates. The phase change of composites during polarization was analyzed by X-ray diffraction and the interface of composites with different PZT mass fraction was characterized by scanning electron microscopy. For application, we used dielectric impedance tester and dynamical experimental setups to analyze the effect of different PZT mass frac- tion to the dielectric and pyroelectric properties of the PZT/PVDF composites. The results show that, the pyro- electric coefficient increases to 4. 1nC/（cm2 · K） at a ceramic mass fraction of 50%.
