Abstract

Membrane technology has opened a new horizon to oxygen enrichment research studies in order to separate this gas from other gases in the air such as nitrogen. This technology has become popular due to its low cost, low energy consumption, and easy access. Recent events in the world and bitter experience of Covid-19 and SARS epidemics have made human society face the challenge of finding a way to fabricate simple and cost-effective oxygen devices and ventilators. From a medical perspective, oxygen separation can be useful for treating aspiration and breathing difficulties. Also, nitrogen gas is required in the food industry and pharmaceutical chemicals. In this review, we provide an overview of polymeric membrane structures, and focus on organic and inorganic compound fillers in membranes. Particular attention is paid to the role of magnetic nanoparticle fillers with different concentrations, sizes, coercivity, and accumulation in mixed-matrix membranes (MMMs), while also investigating synergistic effects of magnetic modules. The roles of external magnetic field and magnetic module are also highlighted in the fabrication and testing processes. Finally, the results of O₂/N₂ gas separation using polymeric and MMM flat sheets are presented and compared, thereby determining future perspectives.

O2/N2气体分离中的聚合物和混合基质膜平板：最新进展，磁性概念和未来展望

膜技术将氧气从空气中的其他气体（如氮气）中分离出来，为富氧研究开辟了新的领域。该技术因其低成本、低能耗和易于获取而受到欢迎。最近世界上发生的事件以及新冠肺炎和SARS疫情的痛苦经历，使人类社会面临着寻找制造简单且具有成本效益的氧气装置和呼吸机的方法的挑战。从医学角度来看，氧气分离对治疗误吸和呼吸困难很有用。此外，食品工业和制药化学品也需要氮气。本文综述了聚合物膜结构的研究进展，重点介绍了有机和无机复合填料在膜中的应用。特别关注不同浓度、大小、矫顽力和在混合基质膜（MMMs）中积累的磁性纳米颗粒填料的作用，同时也研究了磁性模块的协同效应。同时强调了外磁场和磁模块在制造和测试过程中的作用。最后，介绍并比较了聚合物和MMM薄片分离O2/N2气体的结果，从而确定了未来的前景。
