The ionomer membrane under the conditions of 20℃ and 0.05 MPa shows better permeaselectivities that the permeability coefficient of CO_2 and CO_2/ N_2 separation factor are 223 Barrer and 65.70, respectively, while CO_2 / CH_4 separation factor is only 14.70. An obvious increase in P_(CO_2) with decreasing pressure difference exhibits a characteristic of facilitated CO_2 transport, which is not disappear and almost unchange after two months. There is no this behavior for N_2 and CH_4. Hence, P_(CO_2) and α_(CO_2/N_2) and α_(CO_2/CH_4) can be enhanced simultaneously.

该离聚体膜显示出良好的CO_2渗透性能，在20℃和0.05MPa压差下，CO_2渗透系数P_(CO_2)和CO_2/N_2分离系数αCO_2/N_2分别高达223 Barrer和65.70.P_(CO_2)和αCO_2/N_2随CO_2压差的降低而(来源：e2b2A2bBC论文网www.abclunwen.com)明显增大，显示出促进输送特征，这一行为即使在膜放置2个月之后并不消失，渗透分离性能变化不大。N_2和CH_4无此性能，因此在气体压差较低时，P_(CO_2)和αCO_2/N_2、αCO_2/CH_4可同时提高。
