The ferroelectric and piezoelectric properties of melt-quenched unoriented poly(vinylidene fluoride-trifluoroethylene) (73 : 27) copolymer films as a function of the number of poling cycles have been studied. The investigation revealed that quenched films exhibit a decrease in D-E hysteresis behavio
In this paper we present new experiments on the switching of the polarization in thin (< 1 ~tm) ferroelectric copolymer films of P(VDF-TrFE). We observed an unexpectedly short switching time for these thin films: The polarization of a 0.2 ~tm thick film could be reversed by poling fields of 600MV/m
## Abstract This work emphasizes the use of vinylidene fluoride and trifluoroethylene copolymer P(VDFβTrFE) as a pyroelectric sensor. The pyroelectric and dielectric properties of the copolymer have been investigated in the temperature interval 150β350βK. The samples were prepared by using a spinβc
