Self-diffusion coefficient of the ions and conductivity of the gels at different PEG content. a Self-diffusion coefficient of [EMIM] and [TFSI] vs. the molar concentration ratio of cPEG/cIL. b Molar conductivity calculated from impedance measurement (Λimp) and estimated from diffusion (PFG) NMR through the Nernst-Einstein relation (ΛNMR), vs. molar concentration ratio of cPEG/cIL. c Sketch of the interaction between ions, PEG molecules, and polymer matrix
