FIG. 2.

(Color online) FTIR spectra of thin PVDF films (a) without and with, (b) 5 wt. %, and (c) 30 wt. % of [EMIM][NO3].

FIG. 3.

Field-emission SEM photographs of the surfaces of thin PVDF films dried at 100 °C (a) without and, (b) with addition of [EMIM][NO3] to the solution, as well as (c) dried at room temperature, with addition of [EMIM][NO3] to the solution.

FIG. 4.

(Color online) A typical ferroelectric hysteresis loop of thin PVDF films prepared with the addition of [EMIM][NO3] to the solution. The blue curve represents the electric-field dependence of the measured current density. The inset shows the triangular bipolar + unipolar waveform used for the hysteresis measurements.

FIG. 5.

(Color online) (a) Example of a quasi-static pyroelectrical measurement (period and amplitude of the sinusoidal temperature oscillation are 300 s and 0.6 K, respectively). The sinusoidal fitting of the short-circuit sample current is shown as bold curve (in red). (b) Temperature dependence of the quasi-static pyroelectric-coefficient p exp and of the phase shift θ of ferroelectric β-PVDF films.

Image of FIG. 6.
FIG. 6.

(Color online) FTIR spectra of thin PVDF films prepared from solutions to which different ionic liquids (as indicated) had been added.
