摘要
通过对近十多年来在聚酰亚胺基气体分离炭膜方面所取得成果的评述,探讨了聚酰亚胺的化学结构、成膜方法、热解工艺条件,以及修饰改性等因素对炭膜气体分离性能的影响.分析了聚酰亚胺基炭膜目前所存在的问题,并对其发展前景进行了展望.
The development of polyimide - based carbon membranes for gas separation was introduced in this paper. By summarizing the present achievements obtained on the aspect of carbon membranes derived from polyimide, it is confirmed that carbon membranes with high gas separation performance can be prepared by adopting the optimum conditions, i.e. molecular chemical structure, membrane formation methods, carbonization conditions and modification. Finally the author pointed out the existing immediate challenges faced by current polyimide- based carbon membranes for gas separation, and proposed the feasible resolutions of the challenges and the evolution of polyimide - based carbon membranes for gas separation.
