Abstract

The product property between thermal expansion and piezoelectricity in composites prepared from piezoelectric ceramics and polymers is presented. A theoretical analysis on the product property is discussed based on series and parallel models of the composites. From the theoretical analysis, the necessary condition for the highest product effect of diphasic composites is discussed. Composites with piezoelectric ceramic PZT particles, TGS grains and BT particles as active component and PVDF as matrix are used as examples. Enhanced pyroelectricity of the composites is observed
