摘要: Porous PZT was fabricated by conventional sintering process in the present study.

Three kinds of polymer materials, with varying hardness, then were injected into the porous PZT to form a PZT/polymer composite with 3-3 connectivity. Such properties as the dielectric constant, the coupling factor, and the hydrostatic piezoelectric constants were characterized. The effect of the polymer-phase hardness on the properties of the composites also was investigated.
