以ＰＺＴ为陶瓷相，以聚偏二氟乙烯（ＰＶＤＦ）为聚合物相，采用热压法制备了串联２－２型样品。测试了串联２－２型压电复合材料的介电、压电性能。实验结果表明，串联２－２型复合材料的压电应变系数ｄ３３及介电常数ε均较小；在低频，由于界面极化引起的夹层损耗，其介电损耗ｔｇδ则较大。 Using PZT as the ceramic phase and polyvinylidene fluoride (PVDF) as the polymer phase, a series of 2-2 samples were prepared by hot pressing. The dielectric and piezoelectric properties of series 2-2 piezoelectric composites were tested. The experimental results show that the piezoelectric strain coefficient d33 and the dielectric constant ε of the series 2-2 composites are small. At low frequencies, the dielectric loss tgδ is larger due to the interlayer loss caused by the interface polarization.
