“…Since the discovery of the piezoelectric behavior of poly(vinylidenefluoride) -PVDF by Kawai [1] and the understanding of the molecular origin of this electroactivity [2][3][4][5], organic ferroelectric materials have attracted the interest of researchers for their potential use in specific applications such as low weight and flexible sensors [6,7], electromechanical devices [8,9] and high-K capacitors [10,11]. Many classes of polymers such as odd-polyamides [12], even odd polyamide copolymers [13], have shown piezoelectric and pyroelectric activities.…”

International audienceThermo Stimulated Current and Dynamic Dielectric Spectroscopy have been applied to investigate dielectric relaxation modes of poly(vinylidene-fluoride trifluoroethylene) copolymer and poly(vinylidene-fluoridetrifluoroethylene-chlorofluoroethylene) terpolymer. The aim of this work is to check the molecular origin of the ferroelectric relaxor behavior of the terpolymer. The combination of data obtained by both dielectricmethods allows us to describe themolecular mobility of the amorphous phase and the cooperativity of the order/disorder dipolar transition in the crystalline phase. The introduction of 1,1-chlorofluoroethylene units in the main chain induces an increase of the Cooperative Rearranging Region size associatedwith less ordered and smaller crystallites. This morphological evolution is responsible of a lack of cooperativity and it explains the dielectric relaxor behavior of the poly(vinylidene-fluoride-trifluoroethylene-chloroethylene) terpolymer

“…Polyvinylidiene (PVDF) and its copolymers with trifluoroethylene (TrFE) have offered great promise on applications including nonvolatile memory 1–3, actuators 4, energy harvesting 5, 6 and artificial organs 7. The addition of TrFE into PVDF allows a stable ferroelectric β‐phase at room temperature that exhibits strong ferroelectric properties without additional preparation, such as mechanical stretching.…”

In order to characterize the piezoelectric properties of 70 nm thick poly(vinylidene fluoride‐trifluoroethylene), P(VDF‐TrFE), films grown by a spin‐coating technique, both nanoscale manipulation and polarization switching were studied using piezoresponse force microscopy (PFM). We varied the annealing temperature from 75 °C to 145 °C and achieved a high‐quality 70 nm P(VDF‐TrFE) film annealed at the temperature of 95 °C. Ferroelectric domains and their properties were confirmed using X‐ray diffraction, grazing incidence reflection absorption Fourier Transform Infrared (GIRA‐FTIR) and PFM analysis. The ferroelectric domains in the film were homogeneously switchable below 5 V with a remnant d33 of 14.9 pm/V. This offers our rationale for a promise in energy harvesting and switchability would be good for plastic electronics. (© 2010 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
