Abstract

Pyroelectric infrared Lithium tantalite [(LiTaO₃), LT] ceramic particles and silver nanoparticles have been incorporated into a polyvinylidene fluoride-trifluoroethylene [P(VDF-TrFE) 70/30 mol%] copolymer matrix to form composite films. The films were prepared using solvent casting method. Electrical properties such as the dielectric constant, dielectric loss, and pyroelectric coefficient have been measured as a function of temperature. In addition, materials' figures-of-merit have also been calculated to assess their use in infrared detectors. The results show that the fabricated silver nanoparticles incorporated lithium tantalite: polyvinylidene fluoride-trifluoroethylene composite films may have a good potential for uncooled infrared sensor applications.
