英文摘要：

The equivalent electrical model of 0-3 piezoelectric composite was proposed to analyze the effect of polymer conductance on the polarization properties of the composite. The relationship between the polarization properties in polyaniline-doped 0-3 lead zireonate titanate/pelyvinylidene fluoride composite and the polymer conductance was studied. Both the theoretical and experimental results show that the polarization of the composite increases with the polymer conductance.
