“…On the other hand, the slope of the straight line (due to material electrode interface) does not vary significantly with temperature, which indicates that no electrochemical degradation of the electrodes occurs during the conductivity measurement. Similar type of explanation has been reported elsewhere [21] in many other systems. Figure 5 shows the variation of relative dielectric constant (ε r ) with frequency of the PNCE films with varying DMMT concentration at room temperature.…”

Abstract. Structural, thermal and electrical behavior of polymer-clay nanocomposite electrolytes consisting of polymer (polyethylene oxide (PEO)) and NaI as salt with different concentrations of organically modified Na + montmorillonite (DMMT) filler have been investigated. The formation of nanocomposites and changes in the structural properties of the materials were investigated by X-ray diffraction (XRD) analysis. Complex impedance analysis shows the existence of bulk and material-electrode interface properties of the composites. The relative dielectric constant (εr) decreases with increase in frequency in the low frequency region whereas frequency independent behavior is observed in the high frequency region. The electrical modulus representation shows a loss feature in the imaginary component. The relaxation associated with this feature shows a stretched exponential decay. Studies of frequency dependence of dielectric and modulus formalism suggest that the ionic and polymer segmental motion are strongly coupled manifeasting as peak in the modulus (M″) spectra with no corresponding feature in dielectric spectra. The frequency dependence of ac (alternating current) conductivity obeys Jonscher power law feature in the high frequency region, where as the low frequency dispersion indicating the presence of electrode polarization effect in the materials.

“…Plasticization is an effective method to improve the conductivity of solid polymer electrolytes. The effect of the plasticizer on the polymer mobility and conductivity depends on the specific nature of the plasticizer including viscosity, dielectric constant, polymer-plasticizer interaction and ion-plasticizer coordination [2,3]. The most used plasticizers are low molecular weight organic solvents such as propylene carbonate (PC), ethylene carbonate (EC), ~/-butyrolactone (yBL), N,N-dimethylformamide (DMF) etc.…”

Abstract. Gel polymer electrolytes consisting of 49% PMMA grafted polyisoprene-LiCF3SO3, were plasticized with propylene carbonate (PC) are reported. The effect of PC on the electrochemical properties of the polymer electrolyte has been investigated. Analysis of FTIR spectra shows the interaction of salt and plasticizers with the polymer chain. The ionic conductivity was measured and exhibited a maximum value of 104 S/cm. The temperature dependence of the electrical conductivity follows the Arrhenius law.

“…The decrease in conductivity for these samples is attributed to ion association and to the decrease in mobility of the ions [35]. According to Qian et al [36] to understand the effect of EC on the conductivity of polymers system, the Li+-EC interaction is important. The addition of EC leads to the formation of Li+-EC complexes.…”

Abstract. Poly(methylmetacrylate)/poly(ethylene oxide) (PMMA/PEO) based polymer electrolytes were synthesized using the solution cast technique. Four systems of PMMA/PEO blends based polymer electrolytes films were investigated:PMMA/PEO + ethylene carbonate (EC) system, (3) PMMA/PEO + lithium hexafluorophosphate (LiPF6) system and (4) PMMA/PEO + EC + LiPF6 system. The polymer electrolytes films were characterized by Impedance Spectroscopy and Fourier Transform Infrared Spectroscopy (FTIR). The FTIR spectra show the complexation occurrring between the polymers, plasticizer and lithium salt. The FTIR results give further insight in the conductivity enhancement of PMMA/PEO blends based polymer electrolytes.
