摘要:
实验采用固相法合成性能良好的PbZr0.52T0.48O3(PZT)陶瓷粉末,通过常压和热压工艺制备0-3型PZT/PVDF(偏聚氟乙烯)压电复合材料,研究了常压和热压工艺、PVDF所占体积分数和极化条件(时间、电场强度)等因素对复合陶瓷压电和介电性能的影响。采用X线衍射仪(XRD)、扫描电子显微镜(SEM)、阻抗分析仪等表征样品的显微结构和电性能。结果表明:最佳极化条件为极化时间30 min,极化强度7 kV/mm,采用热压工艺制备的复合陶瓷性能更佳; 当PVDF体积分数为10%时,PZT/PVDF压电复合材料的性能最佳,其介电损耗低至1.7%,相对介电常数为191,压电常数为42 pC/N。
Abstract:
PbZr0.52T0.48O3(PZT)ceramic powders were prepared by solid-state coordination reaction,and PZT/PVDF piezoelectric composite ceramics(0-3 type)were prepared with polyvinylidene fluoride(PVDF)by room pressing and hot pressing, respectively.The influences of two process conditions,volume percent of PVDF,poling conditions(polarizing electric field and time)on dielectric and piezoelectric properties for PZT/PVDF composite ceramics were investigated.The microscopic structure and electrical properties were characterized by powder X-ray diffraction(XRD),scanning electron microscope(SEM)and precision impedance analyzer.Results indicated that the optimal poling conditions were polarizing electric field of 7 kV/mm,poling time of 30 min.Better composite ceramics were obtained when it was prepared by hot pressing under the conditions of the volume percent of PVDF of 10%:the dielectric loss(tan δ)of 1.7%,relative dielectric constant(εr)of 191,and piezoelectric constant(d33)of 42 pC/N.
