摘　　要：采用固相法合成了性能良好的PZN-PZT陶瓷粉体。将压电陶瓷粉体分散于PVDF基体中,制备了0-3型PZN-PZT/PVDF压电复合材料。研究了复合材料的复合工艺、极化参数与压电陶瓷的含量对复合材料压电性能的影响。结果表明,溶液混合工艺较好,且当极化电场强度为6kV·mm-1、温度为110℃进行极化20min时,陶瓷粉体质量分数为90%的复合材料的压电性能最好,压电常数d33值达35.9pC·N-1。The piezoelectric PZN-PZT powders were prepared by solid state sintering technique. PZN-PZT/PVDF 0-3 composites were fabricated by dispersing PZN-PZT powders into the PVDF polymer matrix. The effects of the process valiable and the content of PZN-PZT powders on the piezoelectric properties of the composites were investigated. The results indicate that solution mixing method was more suitable to prepare the PZN-PZT/PVDF composites which have good piezoelectricity. The highest d33 attains 35. 9 pC · N^-1, was obtained to the composites which contain 90wt% ceramic powders and was polarized under 6kV · mm^-2 for 20 min at 110℃.
