炭分子筛膜是一种新型无机分离膜,具有耐高温、耐酸碱、高气体选择性的特点,但其通量较低,如何进一步提高炭膜的气体通量,实现炭膜对气体的针对性分离已经成为当前研究的热点.综述了近年来功能炭分子筛膜的研究进展,提出了炭分子筛膜功能化主要存在的问题,着重讨论了采用化学功能化和物理填充无机粒子等方法对炭分子筛膜进行功能化的研究状况.展望了今后炭分子筛膜功能化技术的发展方向.
Carbon molecular sieve membrane is a novel inorganic membrane developed in recent years. In con- trast conventional polymeric membranes, carbon membrane with high selectivity can perform the separation of gas molecule under harsh conditions such as elevated temperature and acidic/alkaline environments. There has been an increasing focus on the improving the gas separation performance of the carbon membrane. The development of functional carbon membranes in recent years was reviewed and the main problems of functionalize the carbon membrane were pointed out. Methods of functionalizing the carbon membrane were discussed and a future direction of developing the functional carbon membranes was introduced.
