Using DC and AC poling methods, three groups of polarized PZT/P 70/30composites have been prepared by poling only the ceramic phase(1), both ceramic and polymerphases in the same(2) and opposite(3) directions. Piezoelectric coefficients of group 1 compositesincrease as the PZT content increasing, while for group 2 composites, the piezoelectric coefficientschange the sign with increasing PZT content because piezoelectricity of copolymer is increasinglycompensated by that of PZT, and PZT content for zero-〓 isn't that for zero-〓. The experimentdata of both group 1 and 2 composites agree well with EMT-Shin model.
