(a) Variation of dielectric constant spectra ε′ vs log{ω(Hz)} of NP1, NP2, NP3, NP4, and NP5 at room temperature. (b) Variation of dielectric constant spectra ε′ vs log{ω(Hz)} of the NP4 (60 wt % NaAlg:40 wt % pectin) biopolymer blend electrolyte at different temperatures. (c) Variation of dielectric loss ε″ vs log{ω(Hz)} of NP1, NP2, NP3, NP4, and NP5 at room temperature. (d) Variation of dielectric loss ε″ vs log{ω(Hz)} of the NP4 (60 wt % NaAlg:40 wt % pectin) biopolymer blend electrolyte at different temperatures.
