摘要:

膜分離技術是最有潛力的高效碳捕集技術之一，具有成本相對較低、分離過程中無相變、可連續操作、能源效率較高等特點。混合基質膜將聚合物與無機填料有機結合，發揮協同增強效應，極大提高了氣體分離效率，從而得到廣泛研究和應用。埃洛石納米管(halloysite nanotubes, HNTs)是一種具有特殊中空納米管狀結構的天然黏土礦物，與其他無機填料相比具有性能優良、價格低廉的優勢。在聚合物基質中加入功能化改性HNTs可增強膜的滲透性和（或）選擇性，改善膜的力學性能和穩定性。綜述了HNTs/聚合物混合基質膜結構和性質、氣體傳輸機制、制備方法以及氣體分離綜合性能的最新研究進展,總結了HNTs/聚合物混合基質膜在天然氣、煙道氣脫碳領域的應用現狀和未來發展方向,為促進HNTs/聚合物混合基質膜的產業化進程提供參考。

Abstract:

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.
