TLDR
In this article , chitosan (CS) and potato starch (PS) biopolymers are blended to prepare proton conducting solid electrolytes based on the X-ray diffraction (XRD) inspection.Abstract:
The need for flexible energy storage devices for advanced technologies has encouraged researchers to focus on environmental-friendly biopolymers. In this work, chitosan (CS) and potato starch (PS) biopolymers are blended to prepare proton conducting solid electrolytes. Based on the X-ray diffraction (XRD) inspection, the most amorphous blended film with the lowest crystallinity degree was selected to prepare polymer electrolytes. The variation in Fourier-transform infrared spectroscopy (FTIR) bands were used to investigate the occurrence of interactions among the ammonium thiocyanate (NH4SCN) salt and CS:PS polymer blends. The experimental results of electrochemical impedance spectroscopy (EIS) were simulated with electrical equivalent circuit (EEC) modeling to determine the circuit elements. The highest value of 1.07 × 10 − 5 S cm−1 was recorded for the sample included 40 wt.% of dopant salt. The dielectric analyses were helpful in separating the regions ascribed to electrode and molecular polarizations. The combination of circuit elements achieved from the EEC modeling and Koops phenomenological interpretation is used to understand the behavior of the loss tangent (tanδ) pattern. The AC conductivity pattern followed Jonscher's power law. The relaxation dynamics interrelated with ions is explained using electric modulus approaches. The peaks hidden in the dielectric loss ( ε ′ ′ ) spectra, were manifested in the imaginary part of electric modulus ( M ′ ′ ) pattern. The M ′ - M ′ ′ patterns were used to shed light on the coupling between ionic motion and polymer chain dynamics. read more

Impedance and dielectric spectroscopy revisited: Distinguishing localized relaxation from long-range conductivity
TL;DR: In this paper, the advantages of plotting a.c. data in terms of impedance, electric modulus, and dissipation factor simultaneously are illustrated, and the degree to which these assignments may be made is related to the dielectric relaxation ratio ( r = ϵ s ϵ ∞ ) and the differences between the time constants of the different relaxation processes present in the material being examined.
