摘要

Diphasic composites of piezoelectric and polymer materials have outstanding properties from device application point of view. These materials offer a possibility of design and fabrication of the materials with definite properties for specific application. Hence these are called smart materials. In this paper we present an outline of this field of research. The mixture rules of dielectric properties of these composites with 0-3 or 3-0.connectivity are presented. The modified equation takes into account the local field interactions. Impedance and electromechanical coupling coefficients of these composites with 2-2 connectivity for circular and rectangular geometry can be estimated. The piezoelectric constants of these materials exhibit Debye-type relaxations. Cole-Cole plots can be drawn. A stress field applied to this material can produce an overall piezoelectricity. Piezoelectric constant of these materials can be related to the elastic and dielectric properties of the component phases. [References: 59]
