Austin Suthanthiraraj 1Received: 22 September 2016 /Revised: 8 April 2017 /Accepted: 11 April 2017# Springer-Verlag Berlin Heidelberg 2017Abstract A new solid polymer electrolyte system basedon poly (vinyl chloride) (PVC) and poly (ethyl methacry-late) (PEMA) containing zinc triflate [Zn(CF 3 SO 3 ) 2 ] saltobtained in the form of thin film specimens using solutioncasting technique has been examined by means of com-plex impedance analysis, thermogravimetry (TG) and dif-ferential scanning calorimetric (DSC) studies, linearsweep voltammetry (LSV) and cyclic voltammetric (CV)measurements. The relevant mechanism of zinc ion trans-port involved in the case of the present polymer blendelectrolyte viz., [PVC (30 wt%)/PEMA (70 wt%)] : xwt% [Zn(CF 3 SO 3 ) 2 ] (where x = 10, 15, 20, 25, 30, and35, respectively) has been evaluated in terms of AC im-pedance method, dielectric and electrical modulus formal-isms. The optimized composition of the chosen blendedpolymer electrolyte system having 30 wt% loading of zinctriflate salt exhibited a single glass transition temperature(T g ) and possessed appreciable levels of thermal and elec-trochemical stability for possible utilization in zincbatteries.Keywords Polymerelectrolyte .

CVIntroductionThestudyofpolymerelectrolytescharacterized with highion-ic conductivity has been of growing importance due to theirprospective applications in electrochemical devices such asenergy conversion units (batteries/fuel cells), electrochromicdisplays, photochemical solar cells, supercapacitors, and sen-sors [1]. Batteries fabricated with polymer electrolytes areknown to possess numerous advantages like high ionic con-ductivity, leak proof, wide electrochemical stability windows,easy processability, and light weight [2].Recently, the development of new polymer compositionsby modifying those existing polymer structures mainly in-cludes introduction of composites, block copolymers, inter-penetrating networks, and polymer blends [3]. The field ofpolymer blends is one of the fast-growing research areas inpolymer physics because of their potential applications espe-cially in electronic materials and electrostatic devices [4]. Theblending of polymers assists in making polymer electrolyteswithhighionic conductivity, betterthermal stability, andgoodmechanical strength. Interestingly, a number of polymerblends reported in literature exhibiting these combined prop-erties are based on poly (ethylene oxide) (PEO)/poly (acrylo-nitrile) (PAN), poly (vinylidene fluoride-co-hexafluoropropylene)(PVDF-HFP)/PAN, poly(methyl meth-acrylate) (PMMA)/poly (vinyl alcohol) (PVA), and poly (vi-nylidene fluoride) (PVDF)/PAN blends. In recent times, theclass of blends obtained between poly (vinyl chloride) (PVC)and poly (ethyl methacrylate) (PEMA) has been a focus ofinterest and emphasized by many researchers so as to prepareelectrolytes for batteries with broad range of device properties[5].Methacrylate family-based polymers like methyl methac-rylate (MMA), ethyl methacrylate (EMA), and butyl methac-rylate are repeatedly being considered in battery industry* C.
