Piezoelectricceramictransducer(PZT)-Poly(vinylidenefluoride)compositeswereprepared by the hot-pressing method. Before addition, PZT particles were firstly modified with two different coupling agents. The micromorphology, microstructure, dielectric properties, and piezoelectric propertiesofthecompositeswerecharacterizedandinvestigated. ResultsindicatedthatPZTparticles were homogeneously dispersed in the poly (vinylidene fluoride) (PVDF) matrix by the addition of coupling agents. The electric properties of PZT-PVDF composites with NDZ-101 were the best. Especially when the volume ratio of the titanate coupling agent NDZ-101 was 1%, the piezoelectric strain constant d33 of PZT-PVDF composites reached maximum value 19.23 pC/N; its relative dielectric constant εr was 67.45; at the same time its dielectric loss tan δ was 0.0766.
