摘　　要：作者以ＰＺＴ和ＰＶＤＦ为原料，采用热压和轧膜两种方法制备了０－３压电复合材料．研究了复合材料的极化工艺和制备工艺．实验结果表明：与轧膜法相比，热压法制备的复合材料样品有较高的介电常数ε和压电常数ｄ３３；在人工极化时，与热压法相比，轧膜法制备的样品的最佳极化电场Ｅ，极化温度Ｔ和极化时间ｔ均有较高的值．composites materials were prepared from PZT and PVDF by hot pressed and rolled films methods. Processings of poling and preparation of composites were investigated. The results show that dielectric constant ε and piezoelectric contant d 33 of composite through rolled films method are lower than those of composites by hot pressed method, and that the optimum poling electric field ( E ), optimum poling time (t ) and the optimum poling temperature ( T ) of composites by rolled films method are higher than those of composites by hot pressed method.
