development for this a pplication. R ealization of such a h igh pe rmeance membrane w ould be a transformational achievement resulting in a membrane based separation technology for post combustion CO2 capture that would exceed the current DOE targets ($20-25 per ton of CO2; <35 % increase in COE) in sensational fashion. Production of a membrane with a selectivity of at least 20 and a permeance of at least 10,000 GPU is the goal. O ne way achieve this goal these high permeances and selectivity is a combination of ILs and membranes. 3.1.6 Challenges and Technology Needs for ILs and Polymer Membranes Unlike t raditional o rganic media, t he p roperties o f I Ls m ay b e ad justed v ia ch emical a lteration of t he cation or anion to produce application specific compounds. Thus, the potential exists to tune the IL such that one o f t he i ons (cation o r a nion) functions as a c omplexing a gent f or t he de sired s orbate, tremendously increasing the sorption capacity of the IL. Recent studies on ILs indicate that the combination o f s ubtle ( e.g., c hanging c ation substitution pa tterns) and g ross (e.g., c hanging t he a nion type) modifications enables very p recise tuning of t he I L solvent properties [ 48]. Changes in solvation properties are possible in this way, thus enabling the rational design of application specific ILs. These so- called “task specific” ILs can also be “tuned” to absorb very high quantities of a specific gas, e.g. CO2. For example, Davis and co-workers reported the synthesis of an IL containing an amine functionality that was capable of absorbing 0.5 mol of carbon dioxide per mole of IL (approx. 6 mL/g IL) [39].

Ionic liquids exceed the “upper bound” observed for polymer membranes.

Further, Condemarin et. al. recently reported exceptional long term stability of SILMs in mixed gas testing [53]. All these data demonstrate the significant potential of IL-SLMs for CO2 capture from flue gas. The ability of materials to perform a particular separation in a membrane format is frequently represented on Robeson plots of selectivity vs. permeability [54].
