A new strategy is successfully applied to "old" acetyl compounds. A free-standing, porous, N-doped carbonaceous membrane is facilely prepared from the thermal treatment of a pyrrole-ring-containing polymeric membrane based on the superacid-catalyzed copolymerization of acetyl monomers. An exceptional ideal CO2 /N2 permselectivity of 43.2 is achieved with a good CO2 permeability of 1149.3 Barrer, exceeding the recent upper bound for CO2 /N2 .
一种新策略成功应用于“旧”乙酰化合物。通过超酸催化乙酰单体共聚,从含吡咯环的聚合物膜的热处理中可简便制备得到一种独立式、多孔、氮掺杂的碳质膜。该膜具有优异的理想 CO2/N2 分离选择性(43.2)和良好的 CO2 渗透性(1149.3 Barrer),超过了 CO2/N2 的最新上限。
