Annealing Effects in Ferroelectric Poly(Vinylidene Fluoride--Trifluoroethylene) Copolymers: Real-Time Studies Using Synchroton Radiation

Poly(vinylidene fluoride--trifluoroethylene) (P(VF sub 2 --TrFE)) copolymers with approx 30 mol% of TrFE exhibit a ferroelectric transition of first-order type around 100 deg C. This transition is investigated using complementary measurements of small angle X-ray scattering and wide angle X-ray diff...

Description
Summary:Poly(vinylidene fluoride--trifluoroethylene) (P(VF sub 2 --TrFE)) copolymers with approx 30 mol% of TrFE exhibit a ferroelectric transition of first-order type around 100 deg C. This transition is investigated using complementary measurements of small angle X-ray scattering and wide angle X-ray diffraction. The results provide information on the properties of both the amorphous and crystalline phases as a function of temperature and on the lamellar morphology. They show that temperature cycling through the Curie transition increases the degree of crystallinity of the polymer and modifies the structure. Graphs, Diffraction patterns, Spectra. 19 ref.--AA
