CO 2的捕获和封存是当前关注的重要问题。采用自由基聚合制备了一种新型聚离子液体，聚四亚乙基五胺丙烯酸盐(PTEPAA)，并对其捕获CO 2性能进行了研究。结果表明，PTEPAA捕获CO 2具有捕获容量高、速度快、高度可逆的特点，在低温捕获的CO 2可以在高温下有效解吸，捕获/解吸过程可以重复进行，PTEPAA可再生。每个捕获/解吸循环，每克PTEPAA可以分离大约0.24克CO 2。PTEPAA作为一种新型固态CO 2捕获材料，在烟气及燃气脱碳领域表现出良好的应用潜力。

A novel ionic polymer, poly(tetraethylenepentamine acrylate) (PTEPAA) was prepared by free radical polymerization and its performance on CO 2 capture was studied. The results show that PTEPAA has extremely high capture capacity, rapid absorption rate and excellent reversibility. CO2 captured at relatively low temperature can be effectively desorbed at higher temperature. The capture/desorption process is reversible which indicates that PTEPAA may be reused. Under typical operation conditions, about 0.24 g CO2 can be captured by per gram of PTEPAA. Therefore, PTEPAA as a new type of solid-state CO2 capture material shows good potential in gas decarbonization.
