A solid polymer blend electrolyte is prepared using poly(vinyl acetate) (PVAc) and poly(methyl methacrylate) (PMMA) polymers with different molecular weight percentage (wt%) of ammonium thiocyanate (NH 4 SCN) by solution casting technique with tetrahydrofuran (THF) as a solvent. The structural, morphological, vibrational, thermal and electrical properties of the prepared polymer blend electrolytes have been studied. The incorporation of NH 4 SCN into the polymeric matrix causes decrease in the degree of crystallinity of the samples. The complex formation between the polymer and salt has been confirmed by FTIR technique. The increase in T g with increase in salt concentration has been investigated. The maximum conductivity of 3.684 × 10 −3 S cm −1 has been observed for the composition of 70PVAc/30PMMA/30 wt% of NH 4 SCN at 303 K. This value of ionic conductivity is five orders of magnitude greater than that of 70PVAc/30PMMA polymer membrane. Dielectric and transport studies have been done. The highest conducting polymer electrolyte is used to fabricate proton battery with the configuration Zn/ZnSO 4 · 7H 2 O (anode) ||polymer electrolyte||PbO 2 /V 2 O 5 (cathode). The open circuit voltage of the fabricated battery is 1.83 V, and its performance has been studied.

“…Recently, there has been an increasing interest to develop the novel solid polymer electrolytes and montmorillonite (MMT) clay added polymer nanocomposite electrolytes (PNCEs) of improved mechanical, thermochemical, electrochemical, and structural stability properties for their technological applications [1][2][3][4][5]. The main factor that rules the ionic conductivity of PNCEs is to suppress the crystallinity of the polymer and ion pair formation (anion complex cation interactions) besides the increase of the number of charge carriers [3][4][5][6][7][8][9].…”

Polymer nanocomposite electrolytes (PNCEs) of poly(ethylene oxide) and sodium perchlorate monohydrate complexes with montmorillonite (MMT) clay up to 20 wt. % MMT concentration of poly(ethylene oxide) (PEO) are synthesized by melt compounding technique at melting temperature of PEO (∼70°C) and NaClO 4 monohydrate (∼140°C). Complex dielectric function, electric modulus, alternating current (ac) electrical conductivity, and impedance properties of these PNCEs films are investigated in the frequency range 20 Hz to 1 MHz at ambient temperature. The direct current conductivity of these materials was determined by fitting the frequency-dependent ac conductivity spectra to the Jonscher power law. The PNCEs films synthesized at melting temperature of NaClO 4 monohydrate have conductivity values lower than that of synthesized at PEO melting temperature. The complex impedance plane plots of these PNCEs films have a semicircular arc in upper frequency region corresponding to the bulk material properties and are followed by a spike in the lower frequency range owing to the electrode polarization phenomena. Relaxation times of electrode polarization and ionic conduction relaxation processes are determined from the frequency values corresponding to peaks in loss tangent and electric modulus loss spectra, respectively. A correlation is observed between the ionic conductivity and dielectric relaxation processes in the investigated PNCEs materials of varying MMT clay concentration. The scaled ac conductivity spectra of these PNCEs materials also obey the ac universality law.
