Membranes, as perm-selective barriers, have been widely applied for gas separation applications. Since some time ago, pure polymers have been used mainly for the preparation of membranes, considering different kinds of polymers for such preparation. At this point, polyimides (e.g., Matrimid5218) are probably one of the most considered polymers for this purpose. However, the limitation on the performance relationship of polymeric membranes has promoted their enhancement through the incorporation of different inorganic materials (e.g., zeolites) into their matrix. Therefore, the aim of this work is to provide an overview about the progress of zeolite embedding in Matrimid5218, aiming at the preparation of mixed matrix membranes for gas separation. Particular attention is paid to the relevant experimental results and current findings. Finally, we describe the prospects and future trends in the field.
膜作为具有渗透选择性的屏障，已被广泛应用于气体分离领域。一段时间以来，纯聚合物主要用于制备膜，制备时会考虑使用不同种类的聚合物。此时，聚酰亚胺（例如Matrimid5218）可能是为此目的最常被考虑的聚合物之一。然而，聚合物膜性能关系的局限性促使人们通过将不同的无机材料（例如沸石）掺入其基质中来提高其性能。因此，这项工作的目的是概述沸石嵌入Matrimid5218的进展，旨在制备用于气体分离的混合基质膜。特别关注相关的实验结果和当前的发现。最后，我们描述了该领域的前景和未来趋势。
