摘要
在气体分离膜领域,传统膜材料常面临着气体渗透性与选择性相互制约的难题,寻求新型聚合物膜材料并探寻分子设计规律成为首要任务.本文综述了一类新型聚合物——蝶烯基聚合物近十年内的研究进展,着重阐述了蝶烯分子在不同种类气体分离膜材料(聚酰亚胺、聚苯并噁唑和自具微孔聚合物等)的结构、调控方式及气体分离性能,考察了碟烯结构在优化气体分离膜微孔结构和提升气体分离性能的贡献和规律,为新一代高性能聚合物气体分离膜的设计及研发提供指导.
In the field of membrane-mediated gas separation,traditional polymeric membrane materials are often challenged by a trade-off between gas permeability and selectivity,thus novel polymeric membrane materials with precise molecule design and high gas separation performance are highly demanded.This paper reviewed the research progress of novel iptycene-based polymeric gas separation membranes in the past decades.In particular,the membrane structure,structure-performance relationship and gas separation properties of iptycene-based polyimides,polybenzoxazoles and polymers of intrinsic microporosity are summarized and discussed.This paper will provide guidance for the design and development of the next generation of high performance polymeric gas separation membranes.
