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 ...
