Abstract

This study presents the transformation of a well recognized membrane material, poly(vinylamine), into a porous adsorbent tailored for direct air capture applications. A scalable synthesis method utilizing water as a solvent was developed to produce cross-linked porous polyvinylamine (PPVAm) sorbents. Stable CO₂ capture capacity of 1.3 mmol/g at 400 ppm of CO₂ was attained with good control over the amine functionality covalently bonded to the polymer backbone. Significantly, this sorbent demonstrated efficient low-temperature regeneration capabilities, thereby further enhancing its practical applicability for carbon capture processes.

低温可再生多孔聚乙烯胺吸附剂的直接空气捕获

这项研究展示了将一种公认的膜材料聚乙烯胺转化为一种适合直接空气捕获应用的多孔吸附剂。以水为溶剂制备交联多孔聚乙烯胺（PPVAm）吸附剂。在CO2浓度为400 ppm时，该聚合物的稳定CO2捕获能力为1.3 mmol/g，并能很好地控制与聚合物主链共价结合的胺官能。值得注意的是，这种吸附剂表现出高效的低温再生能力，从而进一步增强了其在碳捕获过程中的实际适用性。
