Absorption changes at the phase transition of ferroelectric copolymers doped by a cyanine dye

At the ferroelectric phase transition in the optically sensitized ferroelectric vinylidene fluoride-trifluorethylene copolymers P(VDF-TrFE) the sharp change of the dye energy level and optical absorption is revealed. In ferroelectric P(VDF-TrFE) copolymer doped by cyanine due to the structural chrom...

Zusammenfassung:At the ferroelectric phase transition in the optically sensitized ferroelectric vinylidene fluoride-trifluorethylene copolymers P(VDF-TrFE) the sharp change of the dye energy level and optical absorption is revealed. In ferroelectric P(VDF-TrFE) copolymer doped by cyanine due to the structural chromic effect is observed, which characterized by the reversible change of the film color at the ferroelectric phase transition.
