Solvent Effect in Imidazole-Based Poly(Ionic liquid) Membranes: Energy Storage and Sensing

Abstract: Polymerized ionic liquids (PILs) are interesting new materials in sustainable technologies for energy storage and for gas sensor devices, and they provide high ion conductivity as solid polymer electrolytes in batteries. We introduce here the effect of polar protic (aqueous) and polar aprotic (propylene carbonate, PC) electrolytes, with the same concentration of lithium bis(trifluoromethane) sulfonimide (LiTFSI) on hydrophobic PIL films. Cyclic voltammetry, scanning ionic conductance microscopy and square wave… Show more

“…This ambiguous observation is clarified by the molar volume of pendant groups [117,118]. Colby et al stated that the increased side group volume, including counterions, reduces Tg until the bigger molar volume limit [119]. After this point, the molar volume of side groups has little effect on Tg.…”

“…The stability of the PIL in different solvents, moisture, or the presence of specific chemicals should be considered [119]. PILs may be susceptible to degradation or swelling when exposed to certain solvents or chemicals.…”

“…Tunability is one of the most prominent advantages of PILs. PILs containing imidazole groups are easily modified at the two ammonium sites, 42 the application of imidazole-based PILs is the most widely studied and distributed in various fields, including batteries, 43 supercapacitors, 44 stationary column coating, 45 environmental protection, 46 natural product extraction, 47 plasmid DNA extraction 48 and various stimulus-response systems. 49 Introducing polysiloxane fragments can obtain PILs with a low glass transition temperature and relatively high ionic conductivity.…”

“…[18][19][20] In that sense, an outstanding example that implies the utilization of CO 2 is its cycloaddition into epoxides to afford cyclic organic carbonates. [21][22][23] These compounds have shown their ability to be used as polar aprotic solvents in chemical processes 24,25 and as electrolyte solvents in lithium-ion batteries. 26,27 It is relevant to point out that a large number of catalyst systems, such as metal-salen complexes, [28][29][30][31][32][33][34][35][36][37][38] metal organic frameworks [39][40][41][42] and ionic liquids, [43][44][45] have been recently prepared to carry out the synthesis of cyclic carbonates with excellent yields and selectivities.…”
