Far-infrared and x-ray studies on poled semicrystalline poly(vinylidene fluoride)

Far‐infrared (FIR) Fourier‐transform transmission spectra and x‐ray diagrams of poly(vinylidene fluoride) films are examined in terms of poling‐field action on the crystalline phase (α and β forms) and on the amorphous phase. We show that the poling field induces an increase of crystallinity in the...

Description
Summary:Far‐infrared (FIR) Fourier‐transform transmission spectra and x‐ray diagrams of poly(vinylidene fluoride) films are examined in terms of poling‐field action on the crystalline phase (α and β forms) and on the amorphous phase. We show that the poling field induces an increase of crystallinity in the α phase as well as in the β phase, and for the latter an orientation of dipoles in the field direction. For samples containing a mixture of phases α and β we note an α to β phase transition, a rotation of the dipoles in the β phase, and an increase of the crystallinity of the sample. Part of the β phase is generated from the amorphous phase.
