摘　　要：二氧化碳( CO_(2))排放问题深受关注,相比于其他处理方式,气体分离膜具有高效节能、环境友好等特点,但传统的聚合物膜问题显著。碳纳米管材料自身性能优异,但易团聚,对 CO_(2)气体本身并不具有很好的亲和性。通对碳纳米管进行表面及结构改性后将其添加到聚合物中或单独制备成膜,既可以很好协调纯聚合物膜渗透性与选择性之间的矛盾,又表现出优异的各项性能。介绍了碳纳米管材料改性方法及其在 CO_(2)气体分离膜中的研究进展,并对相关问题及机理进行了分析。Carbon dioxide emission has attracted much attention.Compared with other treatment methods, gas separation membrane has the characteristics of high efficiency, energy saving and environment-friendly.However, the traditional polymer membrane has significant problems.Carbon nanotube materials have excellent properties, but they are easy to agglomerate and do not have good affinity for CO_(2)gas itself.By modifying the surface and structure of carbon nanotubes and adding them to polymers or preparing films alone, they could not only coordinate the contradiction between permeability and selectivity of pure polymer membranes, but also showed excellent properties.In this paper, the modification methods of carbon nanotube materials and their research progress in carbon dioxide gas separation membranes were introduced, and the related problems and mechanisms were analyzed.
