In this paper, ferroelectric poly(vinylidene fluoride) (PVDF) films with a thickness of about 430 nm were obtained by spin coating from a solution that contained a small portion of the ionic liquid 1-ethyl-3-methylimidazolium nitrate ((EMIM)(NO 3)).

Uniaxial stretching of P(VDF-HFP) films with optimized stretching parameters does not significantly increase the elastic modulus at room temperature, but induces an enhanced electric polarization. This may explain their outstanding electro-mechanical

Two deep trap levels (4.1 eV and 5.2 eV) were revealed in pure and in DANS-doped Topas® 8007 films by means of PSD, in contrast to the TSD results that point towards only one trap level at 0.75 eV. In the future, measurements with non-polar dyes inc
