In order to tune thestrength of ionic cross-links through charge delocalization of ionpairs, we study a series of four DIGs obtained from the combinationof a cationic PIL (<strong>PIL</strong>^{<strong>+</strong>}) containingpendant imidazolium groups and free bis(trifluoromethylsulfonyl)imide(TFSI) counteranions with four anionic PILs (<strong>PIL</strong>^{<strong>–</strong>}) bearing pendant sulfonate anions andvarious free counter cations (i.e., 1-methyl-3-butylimidazolium, trimethylpropylammonium,tetrabutylammonium, and tetrabutylphosphonium). These new DIGs areproduced via the formation of ionic cross-links with ion pairs havingmore localized charges (i.e., cations paired with sulfonate insteadof TFSI). This results in stronger electrostatic interactions withcounterions, reducing their mobility and significantly increasingthe enthalpic driving force for ion exchange-induced coacervation.As a consequence, the four resulting DIGs release different free ionicliquids (ILs) consisting of TFSI anions associated with imidazolium,ammonium or phosphonium cations. The physical, ion-conducting, andviscoelastic properties of the resulting DIGs are systematically investigatedby differential scanning calorimetry, broadband dielectric spectroscopyand rheology.
