Piezoelectric relaxation in ferroelectrics and polymers
Ferroelectrics, 1982Abstract Until recently a fairly large number of studies have been reported on piezoelectric relaxations in polymers. The relaxational behaviors are often complicated, reflecting the composite structure of polymeric materials. On the other hand, studies of piezoelectric dispersions in hard crystals are very scarce, because usually the dispersion occurs

Polarization Reversal of Ferroelectric Polymers
Japanese Journal of Applied Physics, 1985Two kinds of effects of the depolarization field in a ferroelectric crystallite of the polymer on its polarization reversal switching are discussed. Space charges on the crystallite-amorphous phase interface reduce the depolarization field, decelerating the polarization reversal.

Recent advances in ferroelectric polymers
Macromolecular Symposia, 1995AbstractIn the Polymer Electroprocessing Laboratory at Rutgers University, we have discovered that the odd‐numbered nylons constitute the second known class of ferroelectric polymers1–3, and that polarized films exhibit piezoelectric properties similar to poly(vinylidene fluoride) (PVF2) and copolymers of PVF2 and trifluoroethylene (PVF2/PVF3). A study

Morphology and structure of polymer electrets and ferroelectric polymers
IEEE Transactions on Electrical Insulation, 1993The author considers how the heterogeneous microstructure of semicrystalline polymers used in electret applications can influence the mechanisms of charge trapping and charge transport. The crystallization of polymer chains is described, and the control of the semicrystalline morphology is discussed.

Ferroelectric polymers and ir detection
Ferroelectrics, 1995Abstract Thomson-CSF/LCR and TCS have carried out research in the field of IR sensors working at room temperature using ferroelectric and pyroelectric copolymers of poly(vinylidene fluoride) and trifluo-roethylene. The copolymers are soluble and easy to process by the standard technique of CCD silicon circuits. This paper describes the realization of a

RECENT DEVELOPMENTS IN FERROELECTRIC POLYMERS
Journal of Macromolecular Science, Part C: Polymer Reviews, 1991Abstract For decades, organic polymers were important only as insulators in the electornic industries. Research on electroactive properties was confined mainly to inorganic materials such as barium titanate, lead zirconate titanate, quartz, silicon, cadmium sulfide, and gallium arsenide.
