TL;DR: In this article, the ionic conductivity has been determined for a (PEO)9LiCF3SO3 polymer electrolyte with added plasticizers, and the results showed that adding 50% of the plasticizers by mol. weight of PEO to the (pEO) 9LiCF 3SO3 complex yielded mechanically stable films with an ionicconductivity of 9.0×10−4

TL;DR: A novel ABA system that can be chemically cross-linked in a second annealing step, thereby providing greatly enhanced toughness and increasing tensile strength by a factor of 5.
Abstract: Self-assembly of ABA triblocks in ionic liquids provides a versatile route to highly functional physical ion gels, with promise in applications ranging from plastic electronics to gas separation. However, the reversibility of network formation, so favorable for processing, restricts the ultimate mechanical strength of the material. Here, we describe a novel ABA system that can be chemically cross-linked in a second annealing step, thereby providing greatly enhanced toughness. The ABA triblock is a poly(styrene-b-ethylene oxide-b-styrene) polymer in which about 25 mol % of the styrene units have a pendant azide functionality. After self-assembly of 10 wt % triblock in the ionic liquid [EMI][TFSA], the styrene domains are cross-linked by annealing at elevated temperature for ca. 20 min. The high ionic conductivity (ca. 10 mS/cm) of the physical ion gels is preserved in the final product, while the tensile strength is increased by a factor of 5.
