Fine Structure in the Poly (vinylidene fluoride) Thin Film Cast from N,N-Dimethylacetamide Solution.

Voltage-induced Infrared Absorption from a Spin-cast Thin Film of Ferroelectric Poly(vinylidene fluoride-co-trifluoroethylene) (P(VDF-TrFE)).

Voltage-induced infrared spectra of annealed spin-cast thin films of ferroelectric poly(vinylidene fluoride-co-trifluoroethylene) (P(VDF-TrFE)) (molar ratio, 3:1) were measured in a stepwise cyclic external electric field. Most of the observed infrared bands originated from the β ferroelectric crystalline phase. The voltage-induced spectral changes were decomposed into zeroth- (original), first...

Revisiting the δ-phase of poly(vinylidene fluoride) for solution-processed ferroelectric thin films.

Ferroelectric poly(vinylidene-fluoride) (PVDF) has, in the past, been proposed as an ideal candidate for data storage applications as it exhibits a bistable, remanent, polarization that can repeatedly be switched by an electric field. However, fabrication of smooth ferroelectric PVDF thin films, as required for microelectronic applications, is a long-standing problem. At present, the copolymer ...

Comparison of crystalline thin poly(vinylidene (70%)â•fitrifluoroethylene (30%)) copolymer films with short chain poly(vinylidene fluoride) films

We compare the photoemission and electron energy loss spectra of crystalline poly(vinylidene-fl uoride with trifl uoroethylene: 70%: 30%), P(VDF–TrFE), fi lms, fabricated by the Langmuir–Blodgett technique and annealed in vacuum, with in situ thermally evaporated fi lms of poly(vinylidene-fl uoride) (PVDF) in vacuum. Th e electronic structure and vibrational modes of the short chain PVDF fi lms...
