Here, direct air capture (DAC) represents an essential need for reducing CO₂ concentration in the atmosphere to mitigate the negative consequences of greenhouse effects, involving systems that can reversibly adsorb and release CO₂, in which polymers have played an integral role. This work provides insights into the development of polymer sorbents for DAC of CO₂, specifically from the perspective of material design principles. The authors discuss how physical properties and chemical identities of amine-containing polymers can impact their ability to uptake CO₂, as well as be efficiently regenerated.
