The dielectric activation map for neat PEF and the PEF-based nanocomposites, in terms of the reciprocal temperature dependence of (a) frequency maxima of the recorded relaxation peaks, logfmax, and (b) the corresponding dielectric strengths, Δε. In (a), the added straight and curved lines connecting the experimental points are fittings of Arrhenius and the Vogel–Tammann–Fulcher–Hesse equations [34].
