Effect of space charges on pyroelectricity in poly-vinylidene-fluoride.

Effect of electron irradiation on poly„vinylidene fluoride-trifluoroethylene... copolymers

Electrical field-induced strain response of electron-irradiated poly~vinylidene fluoride-trifluoroethylene! copolymer has been studied by a Mach–Zehnder type heterodyne interferometer in the frequency range of 3–9 kHz. The electrostrictive constant is calculated from the strain results, which is of the same order of magnitude as those obtained at 1 Hz by a bimorph-based strain sensor but at muc...

Quantum Modelling of Poly(vinylidene Fluoride)

Isothermal Melt Crystallization Kinetic Behavior of Poly (vinylidene fluoride)

Isothermal melt crystallization kinetics of PVDF was investigated by differential scanning calorimetry. Thin PVDF film has been fabricated by the solvent casting technique using dimethylformamide (DMF). Then, the samples were melted and subsequently crystallized in the range of the crystallization temperature (Tc) between 138 and 145 °C. The crystallization kinetics was derived from Avrami equa...

Multiferroic tunnel junctions with poly(vinylidene fluoride)

Density Functional Theory calculations of the ferroelectric poly(vinylidene fluoride- chlorotrifluoroethylene) copolymer, compared to those of poly(vinylidene fluoride)

The quantum mechanics calculations of the energetics and structures corresponding to the different representatives structural conformations of poly(vinylidene fluoridetrifluoroethylene) and poly(vinylidene fluoridechlorotrifluoroethylene) copolymers show that the all-trans, Tp conformation, is energetically stabilized even with a chlorine substituent. The changes in the molecular arrangement as...
