基于聚合物膜的气体分离在工业中得到了广泛的应用，例如碳捕获、氢气回收、天然气脱硫以及氧气富集。商业气体分离膜需要具有高气体渗透性和选择性，同时加工成本效益高。混合基质膜（MMM）具有由聚合物和填料组成的复合结构，因此具有两种材料的优点。为了提高 MMM 的气体分离性能以及一般膜性能（例如机械强度和热稳定性），人们付出了很多努力。该观点描述了 MMM 在碳捕获应用中的潜在用途，探讨了它们在制造方面的局限性和克服这些局限性的方法，并讨论了它们在工业气体条件下的性能。
Polymeric membrane-based gas separation has found wide applications in industry, such as carbon capture, hydrogen recovery, natural gas sweetening, as well as oxygen enrichment. Commercial gas separation membranes are required to have high gas permeability and selectivity, while being cost-effective to process. Mixed matrix membranes (MMMs) have a composite structure that consists of polymers and fillers, therefore featuring the advantages of both materials. Much effort has been made to improve the gas separation performance of MMMs as well as general membrane properties, such as mechanical strength and thermal stability. This perspective describes potential use of MMMs for carbon capture applications, explores their limitations in fabrication and methods to overcome them, and addresses their performance under industry gas conditions.
