Polyetherimide (PEI) is an extraordinary type of polyimide with excellent thermal and mechanical properties. The polymer is also gas permeable and is considered one of the best membranes for gas separation. Despite the high selectivity, PEI suffers from low permeability due to the trade‐off between phenomena in polymers. To overcome this limitation, fillers are added during the membrane preparation to create voids for better gas transport. In this paper, permeability and selectivity data of PEI membranes for the separation of oxygen, carbon dioxide, and helium are discussed. The paper also summarizes the reported studies for adding fillers to improve the membrane performance.

用于气体分离的聚醚酰亚胺膜的最新进展

聚醚酰亚胺（PEI）是一种非凡类型的聚酰亚胺，具有出色的热性能和机械性能。聚合物也是透气的，被认为是用于气体分离的最佳膜之一。尽管选择性高，但由于聚合物中现象之间的折衷，PEI的渗透性仍然很低。为了克服这一限制，在膜制备过程中添加了填料，以形成空隙，以更好地进行气体传输。本文讨论了用于分离氧气，二氧化碳和氦气的PEI膜的渗透性和选择性数据。本文还总结了已报道的有关添加填料以改善膜性能的研究。
