摘　　要：膜分离技术是最有潜力的高效碳捕集技术之一,具有成本相对较低、分离过程中无相变、可连续操作、能源效率较高等特点。混合基质膜将聚合物与无机填料有机结合,发挥协同增强效应,极大提高了气体分离效率,从而得到广泛研究和应用。埃洛石纳米管(halloysite nanotubes,HNTs)是一种具有特殊中空纳米管状结构的天然黏土矿物,与其他无机填料相比具有性能优良、价格低廉的优势。在聚合物基质中加入功能化改性HNTs可增强膜的渗透性和(或)选择性,改善膜的力学性能和稳定性。综述了HNTs/聚合物混合基质膜结构和性质、气体传输机制、制备方法以及气体分离综合性能的最新研究进展,总结了HNTs/聚合物混合基质膜在天然气、烟道气脱碳领域的应用现状和未来发展方向,为促进HNTs/聚合物混合基质膜的产业化进程提供参考。Membrane separation technology is one of the most potential high-efficiency carbon capture technologies,with advantages such as relatively low cost,no phase transition during separation,continuous operation,and high energy efficiency.Mixed matrix membranes organically combine polymers and inorganic fillers to exert a synergistic enhancement effect,which greatly improves the gas separation efficiency,and thus has been widely studied and applied.Halloysite nanotubes(HNTs)are natural clay minerals with a special hollow nanotube-like structure,which have the advantages of excellent performance and low price compared with other inorganic fillers.Incorporation of modified HNTs into polymer matrix is expected to lead to higher permeability and/or selectivity of membranes,and improve long-term stability,mechanical properties,and thermal stability of membranes.This paper reviews the latest research progress on the structure and properties,gas transport mechanism,preparation methods and gas separation comprehensive performance of HNTs/polymer mixed matrix membranes.The application status and future development direction of HNTs/polymer mixed matrix membranes in the field of natural gas and flue gas decarbonization are summarized.This review has guiding significance for promoting the industrialization process of HNTs/polymer mixed matrix membranes.
