摘要：

The search for new materials for pyroelectric infrared sensors and ultrasonic transducers has led to the design of ferroelectric composites [1-4]. Recent studies on pyroelectric-polymer composites do show their usefulness in large area, light weight, high strength and flexible infrared sensing devices [2, 3]. Among available materials, deuterated triglycine sulfate (DTGS) shows highest pyroelectric performance [5]. The current work describes the fabrication of DTGS:PVDF composites with varying DTGS particle size powders and composition embedded in poly-vinylidene fluoride (PVDF) matrix which is also an important pyroelectric polymer. In this communication we report the results of investigation of the dielectric and pyroelectric properties of new composites. Using these properties, applicable materials figures of merit are calculated for their use in infrared detecting devices, and are also compared with investigated pyroelectric composites. The results are encouraging for their use as infrared sensors.
