Ferroelectric-to-paraelectric phase transition of vinylidene fluoride-trifluoroethylene copolymer
Abstract
The ferroelectric properties of vinylidene fluoride-trifluoroethylene copolymer were studied. The infrared absorption spectra and x-ray diffraction patterns of the melt-crystallized film suggested the similar crystalline form to the polar form I of polyvinylidene fluoride. It was found that the ferroelectric-to-paraelectric phase transition occurred at 70 °C and was the first order in the melt-crystallized copolymer film by studying the dielectric constant, piezoelectric constant, D-E hysteresis loop, and DSC measurement. The Curie constant was 2200 K. The phase transition was accompanied by the expansion of the crystal lattice.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
