Paper Abstract

Using a solution casting technique, for sample preparation, pyroelectric multi-walled carbon nanotubes in polyvinylidene fluoride composite films have been fabricated, to allow the characterization of both the pyroelectric and dielectric properties of such composites. The properties measured include: (1) dielectric constants and (2) pyroelectric coefficient as a function of temperature. From the foregoing parameters, figures-of-merit, for infrared detection and thermal-vidicons, were calculated. The results indicated figures-of-merit of composite film were higher than pristine polyvinylidene fluoride films. Additionally, composite films, composed of pyroelectric Lithium tantalate [(LiTaO3), LT] ceramic particles and silver nanoparticles incorporated into polyvinylidene fluoride-trifluoroethylene [PVDF-TrFE) 70/30 mol%] copolymer matrix, have been prepared. The results indicate that silver nanoparticles incorporated lithium tantalate:polyvinylidene fluoride-trifluoroethylene composite films may have application for un-cooled infrared sensor.
