Optimal Molecular Design Of Poly (Ionic Liquids) For Co2 Capture From The Atmosphere, Kun Ge, Tao Wang

CO2 Summit II: Technologies and Opportunities

Polymeric ionic liquids (PILs) are promising CO₂ adsorption materials for that they combine the unique properties of ionic liquids with the flexibility and properties of macromolecular architectures. Previous studies have demonstrated that a carbonated-functionalized quaternary ammonium based PIL could adsorb CO₂ from atmosphere when dry and release CO2 when wet, which constituted a moisture swing cycle, which provides an economical approach for air capture. Moreover, the performance of the PIL (such as CO₂ affinity, reaction kinetics, swing size and hydrophobicity), could be improved owing to its fine tunability. To find out its optimal structure, molecular simulation was …
