PREPARATION AND PROPERTIES OF 0-3 PZT/PVDF PIEZOELECTRIC COMPOSITE WITH SOLUTION-MIXING METHOD

The PZT/PVDF piezoelectric composite was fabricated with solution-mixing method. The PZT piezoelectric powders prepared by hydrothermal synthesis method possess many fine properties. The appropriate solvent, used to mix the polymer and the ceramic powders, was selected by comparing the adsorption of PVDF on the ceramic powders. The dried composite powders were pressed into shape for poling and properties measurement. The experimental results show that the powders synthesized by hydrothermal method can improve the dispersing level and the piezoelectric and dielectric properties.
