Here, we present novel chemical sorbents based on polymers with intrinsic microporosity (PIMs). For the first time, alkylamines were incorporated in PIMs through an acid–base interaction to create a chemisorbent. The amine-appended PIMs not only showed a nearly four-fold enhancement in CO₂ loading capacity (36.4 cc/g at 0.15 bar and 298 K) and very high CO₂/N₂ selectivity compared to neat PIM-1 but also proved to have stable performance when cycled between adsorption and desorption isotherms under both dry and humid conditions that are typical for postcombustion CO₂ capture.

通过酸碱和氢键相互作用利用伯胺基团的本征微孔化学吸附剂聚合物

在这里，我们介绍了基于具有固有微孔性（PIM）的聚合物的新型化学吸附剂。第一次，烷基胺通过酸碱相互作用被引入PIM中以产生化学吸附剂。与纯PIM-1相比，添加胺的PIM不仅显示出CO ₂负载量提高了近四倍（在0.15 bar和298 K时为36.4 cc / g）和非常高的CO ₂ / N ₂选择性，而且证明了在干燥和潮湿条件下（燃烧后CO ₂捕集的典型条件）在吸附和解吸等温线之间循环时，具有稳定的性能。
