摘　　要：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。In the paper,the samples of 2 2 piezocomposites with series model were prepared from PZT and PVDF by hot pressed method.The dielectric and piezoelectric properties of samples were measured.The results showed that piezoelectric strain coefficient d 33 and dielectric constant ε of composites were lower,and that at low frequency,due to interlayer loss caused by interface polarization,dielectric loss tg δ was a higher value.
