共轭微孔聚合物(CMPs)在碘吸附领域的应用

Application of Conjugated Microporous Polymers(CMPs)in the Field of Iodine Adsorption

核工业废料中放射性碘的富集严重威胁着人类的健康,因此,近年来碘的有效捕获备受研究者们的关注。共轭微孔聚合物(CMPs)由于具有较高的比表面积、永久可调的孔隙率、可控的结构以及高的热/化学稳定性等优点,使得CMPs材料在碘吸附领域备受关注。主要综述了具有高效碘捕获能力的CMPs的研究进展,分析并讨论了π-共轭骨架、富π-电子杂环大分子、富电子杂原子基团(如氮、噻吩、氟)等关键结构的作用。

The enrichment of radioactive iodine in the waste of nuclear industry is a serious threat to human health.Therefore,the effective capture of iodine has attracted the attention of researchers in recent years.Conjugated microporous polymer(CMPs)has become an excellent candidate in the field of iodine adsorption because of its high specific surface area,permanently adjustable porosity,controllable structure and high thermal/chemical stability.In this review,we focus on the research progress of CMPs with high efficiency of iodine capture,and analyze and discuss the role of π-conjugated framework,π-electron rich heterocyclic macromolecules,electron rich heteroatomic groups(such as nitrogen,thiophene,fluorine)and other key structures.
