Novel mixed matrix membranes based on polymerizable room-temperature ionic liquids and SAPO-34 particles to improve CO2 separation

Investigation of gas permeation properties of film forming polymeric ionic liquids (PILs) based on polybenzimidazoles

“…Such new material development would be helpful not only for CO 2 capture from the flue gas, but also in other applications such as natural gas sweetening, enhanced oil recovery, water gas shift reaction, etc. In some of these applications, membrane based separation processes are proved to be advantageous over conventional processes due to their operational simplicity, high reliability, light weight and modular nature leading to easy scale-up, lower capital costs and most importantly, environment friendly nature owing to the physical nature of separation (except for membrane contactors, where physical nature of separation may not be applicable) [3,[9][10][11][12]. A long term sustainability of the membrane material while maintaining its high CO 2 selectivity under different environmental conditions is a major challenge and needs to be addressed in order to make the membrane based processes techno-economically viable.…”

Polybenzimidazole based polymeric ionic liquids possessing partial ionic character: Effects of anion exchange on their gas permeation properties

“…The key problem with most of the demonstrated PILs is that they are mechanically weak and thus could not be used as membranes at higher pressure [6,14,15]. To conquer this issue, various methodologies, such as crosslinking [15][16][17][18][19][20], copolymerization [14,21,22], polymerization of IL-monomers on porous polymer support [15,17,20,23,24] and recently, PILs based on N-quaternization of fully aromatic polybenzimidazole (PBI) backbone [25][26][27] are being explored.…”

Synthesis, Structural Analysis and Antimicrobial Activities of Novel Water Soluble Ionic Liquids Derived from N-Heterocyclic Carbene Salts

“…[6][7][8][9] Also, some researchers have investigated them for their use in electrochemical applications too. [10][11][12] Recent days they have been subjected to physical explorations because of their liquid phase properties such as liquid-liquid equilibrium and solubilities in other liquids, [13][14][15] and tested NHC derivative ILs in supported membrane studies, extraction [16,17] and in nanochemistry too. [18,19] N-heterocyclic carbenes (NHCs) are cyclic compounds containing one or mostly two N atoms in the main C ring (Figure 1).…”
