“…With the addition of SN, the high-frequency arc is disappeared and indicates that total conductivity is owing to the cation only (σ = ne). The same feature has been reported earlier also [41][42]. Although nature of the plot is same for all solid polymer electrolytes with some change in the arc shape.…”

Abstract:Herein, we present preparation of solid polymer electrolyte (SPE) comprising of PEO, NaPF6 and varying fraction of Succinonitrile (SN) by standard solution cast technique. The morphological features and structural properties were studied by the FESEM, XRD, respectively. FTIR was performed to study the interactions between polymer host, salt, and SN. Impedance spectroscopy, Transference number measurements, LSV and CV were used to examine the electrochemical properties. The complex permittivity/conductivity & modulus were studied to understand the dielectric properties by evaluating the dielectric strength, relaxation time, hopping frequency and dc conductivity. Based on the experimental results an interaction mechanism is presented.

“…The characterization results of the obtained D 2 and D 3 by the elemental analysis, IR, 1 H NMR, and 13 C NMR show that the methylation and quaternization of the PAMAM are relatively complete. The liquid chromatogram also shows a relatively acceptable monodispersity for D 2 and D 3 .…”

“…Solvent-free polymeric electrolytes based on poly(ethylene oxide) (PEO) and poly(propylene oxide) (PPO) have been extensively studied over the past two decades [1][2][3] . However, PEO and PPO systems are found to be bi-ionic conductors, in which both cations and anions contribute to ionic conduction.…”

SUMMARY:The quaternary ammonium salts of dendritic poly(amidoamine) generations 2 and 3 are prepared by methylation and quaternization with methyl iodide. The obtained dendritic anion conductors exhibit a conductivity of 10 -5 -10 -6 S N cm -1 at ambient temperature. The plots of conductivity vs. temperature are curves with the lowest point around 58 8 C, which appear to exhibit a substantially different conductive law compared with ordinary linear or comb-like polyelectrolytes.

“…The conductivity measurements were carried out at four different temperatures from 303 K to 333 K. An impedance plot, real vs. imaginary parts of impedance for the film A2 (PVA-PEG 600 -(MgNO 3 ) 2 : 40-50-10) is shown in FIG2. The absence of semicircle portion in the impedance curve leads to a conclusion that the current carrirers are ions and this leads one to further conclude that the total conductivity is mainly the result of ion conduction [11]. …”

Poly vinyl alcohol (PVA) and polyethylene glycol (PEG) blend based Mg 2+ ion conducting polymer electrolytes have been prepared. Polyethylene glycol (PEG) with three different molecular weights 200,400 and 600 has been used and the effect of this molecular weight on the ionic onductivity of the electrolytes is studied through XRD, ac impedance technique. The analysis shows that the PEG with mol.wt 600 is more effective in reducing the crystallinity and enhancing the conductivity properties of the electrolytes.
