摘要
采用溶液混合法制备 PZT/ PVDF压电复合材料。首先用固相法制备出适合溶液混合的 PZT陶瓷粉末 ,并且通过陶瓷粉末对 PVDF的吸收量选择乙醇为 PVDF的溶剂进行混合 ,然后烘干制备出 PZT/ PVDF复合粉末 ,再成型极化。实验结果表明这种复合方法提高了 PZT陶瓷颗粒在 PVDF有机基体中的分散度 ,使制得的材料内部均匀 ,结构致密 ,从而提高了 PZT/ PVDF压电复合材料的压电和介电性能。
In this paper, the PZT/PVDF piezoelectric composite was fabricated with solution mixing method. First, the PZT piezoelectric powders prepared by oxide sintering technique, synthesis method possess many fine properties. Then, the appropriate solvent, ethanol was used to mix the polymer and the ceramic powders. Finally, the dried composite powders were pressed into shape for poling and properties measurement. The measurements show that the powders synthesized by hydrothermal method can improve the dispersing level and the piezoelectric and dielectric properties.
