摘要: The Raman and Infrared (IR) spectra of poly(methyl methacrylate) (PMMA) membranes plasticized by ionic liquids the (1 − x)[1-butyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide (BMITFSI)],xLiTFSI type, where BMI+ is 1-butyl-3-methylimidazolium cation TFSI− anion, are analyzed for a lithium bis(trifluoromethane sulfone)imide (LiTFSI) mole fraction x = 0.23 PMMA contents from 0 to 50 wt%. found have an average coordination about three CO groups less than one anion. It plays role cross-linker between ester nonvolatile liquid. Addition x)(BMITFSI),xLiTFSI liquid lowers conductivity but might improve transference number transforming [Li(TFSI)2]− anionic clusters present in pure into mixed anions.
