Effect of Plasticizers on Ionic Association and Conductivity

Infrared spectroscopic studies of the effect of the plasticizers ethylene carbonate, tetraethylene glycol, and tetraethylene glycol dimethyl ether on the (PEO)xLiCF3SO3 system are reported. These data are augmented by measurements of the ionic conductivity. Relative concentrations of the various ionic species present have been determined as a function of plasticizer content. The plasticizers ...

effect of plasticizers (ec or pc) on the ionic conductivity

Effect of plasticizers (EC or PC) on the ionic conductivity

In present work, we have shown the ionic conductivity can be substantially enhanced by using the combined effect of the plasticizers as well as the inert filler. It was revealed that the incorporating 15 wt.% Al 2 O 3 filler in to PEO: LiTf polymer electrolyte significantly enhanced the ionic conductivity [σ RT (max) = 7.8 × 10 −6 S cm −1].

Effect of plasticizers on ionic conductivity and dielectric

In this paper, we report the effect of different plasticizers, such as poly ethylene glycol, propylene carbonate, ethylene carbonate and dimethyl carbonate on the ionic conductivity and dielectric relaxation of PEO-LiClO 4 solid polymer electrolytes. The highest ionic conductivity is obtained for polymer electrolyte plasticized with poly ...

Plasticizer - an overview | ScienceDirect Topics

Plasticizers are added to materials to make them softer and more flexible; some plasticizers are more efficient at this than others. Plasticizer efficiency is used to describe the ability of a plasticizer to make the product softer and is reported as a ratio of the slope of the hardness versus plasticized concentration to the slope of that found for DOP.

Enhanced ionic conductivity of intrinsic solid polymer

The ionic conductivity of the polymer electrolytes using the linear plasticizer abruptly decreases below 0 °C, while the temperature dependence of the ionic conductivity of the polymer electrolytes based on the multi-armed plasticizers shows a typical Vogel-Tamman-Fülcher (VTF) relationship in the temperature range from -30 to 100 °C.
