Ferroelectric polarization and pyroelectric activity of functionalized P(VDF-TrFE) thin film lead free nanocomposites

The ferroelectric, pyroelectric, and dielectric properties of 0–3 nanocomposite systems of ferroelectric (Bi0.5Na0.5)TiO3-(Bi0.5K0.5)TiO3-BaTiO3 ceramics with a vinylidene fluoride/trifluoethylene copolymer were investigated. It was observed that the interface effect between the polymer matrix and n...
