Syntheses and characterization of new poly(ionic liquid)s designed for CO2 capture

Polymeric ionic liquids for CO2 capture and separation: potential, progress and challenges

“…43,[48][49][50][51] Likewise, other polymers such as vinylbenzyl-tributylammonium, methacrylate dimethylheptylammonium and diallyldimethyl ammonium based PIL-10, PIL-12a-c and PIL-13a-j have also been probed for their CO 2 uptake. 42,52,53 Instead of using the aforementioned cations, recently Einloft et al 54 adopted two different approaches to fabricate novel polyurethanebased PIL-16 to PIL-18; first route involved a single step cationic polymer synthesis while second method produced the anionic polyurethane in two steps ( Figure 3). Imidazolium cation incorporated in backbone of polyurethane (PIL-16) showed lower CO 2 sorption (56.3 mol %) relative to the imidazolium used as a counter-cation in PIL-17a (62.3mol %) at 5 bar.…”

Novel pyrrolidinium-based polymeric ionic liquids with cyano counter-anions: High performance membrane materials for post-combustion CO2 separation

“…The lack of diversity in what concerns the different chemical structures of cations and anions is another key issue, since the majority of the efforts to use PIL-IL membranes for CO 2 separation used imidazolium moieties as pendant groups of the polycation backbone and the bis(trifluoromethylsulfonyl)imide ([NTf 2 ] À ) as counter-anion [57][58][59][60][62][63][64][65].…”

Development of Inexpensive Cellulose-Based Sorbents for Carbon Dioxide

“…The amine functionalization reaction is described elsewhere (Bernard et al, 2016;Magalhaes et al, 2014). In a Schlenk flask, under N 2 atmosphere 1g of citric acid modified cellulose was added to the amine (molar ratio COOH/AMINE = 1:1) dissolved in 15 mL of dimethylformamide (DMF).…”
