A new approach to highly conductive polymer electrolytes: synthesis of gelling fluoroalkylated end-capped 2-acrylamido-2-methylpropanesulfonic acid copolymers containing poly(oxyethylene) units

New fluoroalkylated end-capped 2-acrylamido-2-methylpropanesulfonic acid copolymers containing poly(oxyethylene) units were prepared by the use of fluoroalkanoyl peroxides. It was demonstrated that these fluorinated copolymers can form gels in DMSO under non-crosslinked conditions, and these fluorinated polymeric gelling electrolytes containing lithium salts exhibit a considerably high ionic conductivity of 10−3 S/cm level at room temperature.
