| 摘 要： | 通过论述炭膜的制备方法及其关键影响因素，系统总结了炭膜的氧氮分离性能，并将其与高性能聚吡咙膜和聚苯胺膜进行了比较，提出了今后的发展方向。指出炭膜具有优异的氧氮分离性能，其氧氮分离因子一般为10以上，最高可达36。聚酰亚胺基和聚吡咙基炭膜均表现出较好的综合氧氮分离性，大大突破了富氧膜材料的Robeson上限，位于极具吸引力的商业化区域，在空气分离中显示出了极大的应用潜力和工业化前景。

| Abstract: | The preparation methods of carbon membranes, their key factors, as well as their separation performance compared with those of polypyrrolone and polyaniline membranes, are summarized. The future research direction is proposed. It is pointed out that carbon membranes possess excellent performance for oxygen and nitrogen separation with the oxygen/nitrogen separation factor of above 10, and a maximum value as high as 36. The polyimide- and polypyrrolone-based carbon membranes show better comprehensive performance for oxygen and nitrogen separation. The performance of these membranes breaks through the Robeson upper boundary, making them commercially attractive. Carbon membranes show great potential for commercial application for directly separating oxygen over nitrogen from air. |
