## Abstract In this article, we reported the studies on the local dualβpeak vibrations in ferroelectric P(VDFβTrFE) films, induced by an alternating voltage with its amplitude high enough to cause polarization reversal. A further study showed that this dualβpeak vibration was caused by ferroelectri
Structural changes in poly(vinylidene fluoride)-trifluoroethylene [P( VDF-TrFE)] copolymers caused by X-ray irradiation were investigated by molecular weight determination, EPR analysis, FTIR spectroscopy, gel content, DSC thermal analysis, Xray diffraction, and piezoelectricity measurements. Sample
A systematic study was carried out on the effect of the crystallization temperature (T cr ), on the phase transitions presented by P(VDF/TrFE) copolymers cast from dimethylformamide (DMF) solution with molar ratios 60/40, 70/30, and 80/20. The results obtained by differential scanning calorimetry (D
