Piezoelectric PZT/Polymer Composite with 3-3 Connectivity

ABSTRACT

The characteristics of the PZT/PMM and PZT/Butadiene composites with 3 dimensional network structure have been investigated as a function of the PZT volume fraction. The dielectric constants of the PZT composites increased linearly as the PZT volume fraction increased. However, they are not significantly affected by the polymer compliance. The piezoelectric d33 coefficients of the PZT/Butadiene are largest than the PZT/PMM because of the high elastic compliance which promotes stress transfer. The values of the mechanical quality factor adn frequency factor of the PZT/PMM composite are slightly larger, while the planar coupling factor is smaller, than the PZT/Butadiene composite. These results are due to strong interaction and mechanical coupling between PZT and PMM.
