热处理对PZT/PVDF压电复合材料电特性的影响

In this paper, PZT ceramic powders were used through the high temperature heat treatment to prepare the PZT/PVDF. And then the microstructure, surface morphology, dielectric properties and piezoelectric properties with and without high temperature treatment were researched. The results show that the porosity of the PZT/PVDF composites were decreased by the heat treatment PZT, at the same time the piezoelectric coefficient and the dielectric constant of the PZT/PVDF composite material were improved sharply.
