A truly cost-effective strategy for the synthesis of amine-tethered porous polymer networks (PPNs) has been developed. A network containing diethylenetriamine (PPN-125-DETA) exhibits a high working capacity comparable to current state-of-art technology (30 % monoethanolamine solutions), yet it requires only one third as much energy for regeneration. It has also been demonstrated to retain over 90 % capacity after 50 adsorption-desorption cycles of CO2 in a temperature-swing adsorption process. The results suggest that PPN-125-DETA is a very promising new material for carbon capture from flue gas streams.
已开发出一种用于合成胺键合多孔聚合物网络（PPN）的极具成本效益的策略。一种含有二乙烯三胺（PPN-125-DETA）的网络具有与当前最先进技术相当的高工作容量（30%单乙醇胺溶液），但再生所需的能量仅为其三分之一。在温度切换吸附过程中，PPN-125-DETA 在 50 次 CO2 吸附-解吸循环后仍保持超过 90%的容量。结果表明，PPN-125-DETA 是从烟道气中捕获碳的很有前途的新材料。
