Poly (vinylidene fluoride) Thin Film Prepared by Roll Hot Press

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...

Quantum Modelling of Poly(vinylidene Fluoride)

Multiferroic tunnel junctions with poly(vinylidene fluoride)

Polymorphism of poly(vinylidene fluoride) induced by poling and annealing

2014 In stretched poly(vinylidene fluoride) films, the transition from unpolar 03B1-form to a polar form (03B1p) is produced by pohng at 80 °C by an electric field of 1 MV/cm. This oriented form has the same lattice constants as 03B1-form but is associated with extra diffuse reflections. This form and the diffuse reflections disappear by annealing above 170 °C and give an oriented and more stab...

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...
