采用溶剂浇铸法制备了PZT含量分别为0、2、4、6、8、10mol%的聚偏氟乙烯（PVDF）。通过XRD、FT-IR和拉曼光谱研究，观察到了明显的β相。这些样品的极化开始于100 Ω/cm的高电场，并且随着外加电场的增加而增加。4mol%PZT掺杂的PVDF显示出最大的极化和高矫顽场。矫顽场也随着外加电场的增加而增加。因此，4摩尔% PZT掺杂的PVDF复合材料可用于高电场应用中。
ABSTRACT PVDF with 0, 2, 4, 6, 8, 10 mole% of PZT has been prepared by the solvent casting method. Prominent β phase has been observed from the XRD, FT-IR and Raman studies. The polarization of these samples starts at high field of 100 kv/cm and it increases with the increase in applied electric field. The 4 mole% PZT doped PVDF shows maximum polarization and high coercive field. The coercive field also increases with the increase in applied electric field. Hence, 4 mole% PZT doped PVDF composites can be used in high electric fields applications.
