“…In the case of ion containing polymers, CO 2 sorption most commonly relies on the use of polymers containing cations of ammonium and imidazolium ions, − with a few examples exploring other cations such as pyridinium and phosphonium. , There is a wealth of literature examples employing each of these cation identities in varied polymer structures including PILs, − ion exchange resins, , and other cross-linked porous polymers. , Importantly, the identity of these cations directly impacts the CO 2 capture capacity of the resulting polymeric sorbents.…”

Anthropogenic activities have resulted in enormous increases in atmospheric CO 2 concentrations particularly since the onset of the Industrial Revolution, which have potential links with increased global temperatures, rising sea levels, increased prevalence, and severity of natural disasters, among other consequences. To enable a carbon-neutral and sustainable society, various technologies have been developed for CO 2 capture from industrial process streams as well as directly from air. Here, direct air capture (DAC) represents an essential need for reducing CO 2 concentration in the atmosphere to mitigate the negative consequences of greenhouse effects, involving systems that can reversibly adsorb and release CO 2 , in which polymers have played an integral role. This work provides insights into the development of polymer sorbents for DAC of CO 2 , specifically from the perspective of material design principles. We discuss how physical properties and chemical identities of amine-containing polymers can impact their ability to uptake CO 2 , as well as be efficiently regenerated. Additionally, polymers which use ionic interactions to react with CO 2 molecules, such as poly(ionic liquids), are also common DAC sorbent materials. Finally, a perspective is provided on the future research and technology opportunities of developing polymer-derived sorbents for DAC.

In this study, an innovative and cost‐effective ionic polymer for CO2 capture and utilization for the first time, using abundant and nonfood‐based biomass lignin is reported. The modified ionic polymer synthesizes through the reaction of glycidyltrimethylammonium chloride with lignin under alkaline conditions to yield quaternary ammonium ionic functionality. Subsequently, the hydroxide‐based pure ionic lignin polymer is employed for CO2 capture from both direct air and concentrated CO2 sources at room temperature and atmospheric pressure. Structural characterization of the polymers is accomplished through 1H, 13C, and 2D‐heteronuclear single quantum coherence (HSQC) NMR, and FT‐IR spectroscopy. The CO2 capture process is established through the formation of bicarbonate ions alongside the presence of CO2. The captured CO2 is precisely quantified by using inverse‐gated proton decoupled 13C NMR with an internal standard (trioxane). Remarkably, the captured‐CO2 amounts of ionic lignin polymer are 1.06 mmol g−1 (47 mg g−1) from concentrated‐CO2 source and 0.60 mmol g−1 (26 mg g−1) from direct‐air. The captured‐CO2 in ionic lignin polymer is released in controlled manner and utilized in the synthesis of cyclic carbonate, showcasing the productive application of the captured carbon. Moreover, the fully controlled recovering of ionic lignin polymer achieves via repeated CO2 release ↔ CO2 capture.
