Abstract:

In recent years, adsorption and separation materials with a flexible three-dimensional framework have attracted significant interest from researchers. Their unique dynamic adsorption behavior and chemically rich structural framework give them properties utterly different from those of traditional rigid adsorption materials. These unique flexible adsorption materials have shown great potential in adsorption and separation, and environmental purification and sensing. However, the development of this field has needed to be faster due to the lack of in-depth understanding of flexible adsorption phenomena and corresponding theoretical research methods by researchers. In this paper, based on the latest research progress in the definition, theoretical development, and classification of flexible adsorption, we provided an in-depth analysis of its application examples in the removal of pollutants and separation of azeotropes and aim to provide the corresponding theoretical help for the development of this field. The article also pointed out the direction and prospect of industrialization of flexible adsorption materials, and efforts should be made to explore the application prospect of flexible adsorption materials for large-scale and high-efficiency treatment of liquid-phase (gas-phase) environmental pollutants with high (low) concentrations so as to promote the industrialization of flexible adsorption materials.

摘要：

近年来，具有柔性三维框架结构的吸附分离材料逐渐引起研究人员极大兴趣，其独特的动态吸附行为和富化学环境的结构框架赋予了其完全不同于传统刚性吸附材料的特性，这种特殊的柔性吸附材料在吸附分离、环境净化和传感等领域显示出巨大潜力。然而，由于研究者们缺少对柔性吸附现象的深入理解和相应的理论研究方法，该领域的发展较为缓慢。本文立足于作者自身研究工作，对柔性吸附的定义、理论发展和分类等方面的最新研究进展以及其在污染物去除、共沸物分离等方面的应用实例进行深度分析，力求为该领域发展提供相应的理论支撑。文中也指出了柔性吸附材料的产业化方向及前景，即应该努力探索柔性吸附材料大规模、高效率地处理环境中高浓度（低浓度）的液相（气相）污染物的应用前景，以此来推动柔性吸附材料的产业化。
