A processable ionogel with thermo-switchable conductivity.

We report an ionogel with thermo-switchable conductivity and high processability based on physical self-assembly of poly(styrene- b -ethylene oxide- b -styrene) (PS-PEO-PS) in mixed ionic liquids composed of thermo-responsive 1,3-dimethylimidazolium bis(trifluoromethanesulfonyl)imide and polymerizable 1-(4-vinylbenzyl)-3-butylimidazolium bis(trifluoromethylsulfonyl)imide, and subsequent chemical crosslinking of the polymerizable component.
