Multilevel Information Storage in Ferroelectric Polymer Memories

Advanced Materials, 2011
Multibit memory devices based on the ferroelectric copolymer P(VDF-TrFE) (poly-(vinylidenefluoride-trifluoroethylene)) are presented. Multilevel microstructures are fabricated by thermal imprinting of spin-coated ferroelectric polymer film using a rigid Si template.

Ferroelectric Polymers

Science, 1983
Piezoelectricity and pyroelectricity, traditionally encountered in certain single crystals and ceramics, have now also been documented in a number of polymers. Recently, one such polymer—poly(vinylidene fluoride)—and some of its copolymers have been shown to be ferroelectric as well.

Relaxor Ferroelectric Polymers

Ferroelectrics, 2006
The relaxor ferroelectric polymers, i.e., the poly(vinylidene fluoride-trifluoroethylene) [P(VDF-TrFE)] based terpolymers and high energy electron irradiated copolymers, provide unique opportunity to investigate the ferroelectric relaxor behavior in polymeric materials.

Relaxor ferroelectric polymers

ISAF 1998. Proceedings of the Eleventh IEEE International Symposium on Applications of Ferroelectrics (Cat. No.98CH36245), 2002
An exceptionally high electrostrictive response was observed in electron irradiated polyvinylidene fluoride-trifluoroethylene (P(VDF-TrFE)) copolymer. Moreover, the transverse strain of the material can be tuned over a large range by different sample treatment conditions.

Ferroelectric polarization in polymers

Ferroelectrics, 1980
Abstract Previous work has shown that a model of oriented dipoles accounts quite well for observed piezoelectric and pyroelectric behavior of amorphous and semicrystalline polymers. The process whereby the dipoles become oriented is the subject of this paper.

Curie Transitions for Attograms of Ferroelectric Polymers

Nano Letters, 2013
Polymer systems having one, two, or three dimensions on the nanometer length scale can exhibit physical properties different from the bulk. The degree of disorder characteristic for large amounts of matter is strongly reduced and changes in symmetry are imposed by means of geometrical confinement.

Ferroelectric polymers and their applications

Ferroelectrics, 1982
The piezoelectric and pyroelectric polymer poly(vinylidene fluoride) (PVF2) was recently classified as a polymeric ferroelectric. The physical properties of PVF2 are reviewed to justify this definition. Applications are classified on the basis of transduction mechanism including electrical to mechanical, mechanical to electrical, thermal to mechanical,

Ferroelectric polymers and applications

Ferroelectrics, 1984
AbstractThis paper reviews the general features of ferroelectricity in polyvinylidene fluoride and related polymers; ferroelectricity is shown as the origin of piezoelectricity, pyroelectricity and high dielectric permittivity. Preparation technologies are discussed, and applications are presented, with special attention to capacitor dielectrics and ...
