Stable and metastable ferroelectric polarization analyzed by the ramp voltage technique
(2002-12-01)
The study of the stable and the metastable ferroelectric polarization of poly(vinylidene fluoride), PVDF, was performed using two successive equal sign ramp voltages, mediated by a short-circuit period. Rates from 10 V/s ...

Comparative study of polyvinylidene fluoride and polypropylene suburethral slings in the treatment of female stress urinary incontinence
(WILEY-BLACKWELL, 2016)
AimsEvaluate the effectiveness and safety of polyvinylidene fluoride (PVDF) transobturator suburethral slings/tapes (TOTs) in the treatment of stress urinary incontinence, and compare them to polypropylene (PP) slings. ...
Broadband dielectric characterization of piezoelectric poly(vinylidene fluoride)thin films between 278 K and 308 K
(Elsevier, 2013-07)
This work describes the dielectric properties of piezoelectric poly(vinylidene fluoride) (PVDF) thin films in the frequency and temperature ranges relevant for usual applications. We measured the isothermal dielectric ...
Influence of the Solvent Evaporation Rate on the Crystalline Phases of Solution-Cast Poly(Vinylidene Fluoride) Films
(JOHN WILEY & SONS INC, 2010)
The influence of the solvent-evaporation rate on the formation of of. and P crystalline phases in solution-cast poly(vinylidene fluoride) (PVDF) films was systematically investigated. Films were crystallized from ...
