Review on the role of nanomaterials in membrane fabrication via additive manufacturing for gas separation

By virtue of the rapid development of technologies in the era of Industrial Revolution 4.0, additive manufacturing technology enables faster production, diverse raw materials, infinite shapes and geometries for fine products as compared to traditional manufacturing methods. Among many manufacturing materials, nanomaterials have attracted extensive attention due to their wide variety, high strength, and effect of catalytic, quantum, surface and boundary. From the aspect of an industrial manufacturing process, the practical advantages of using additive manufacturing techniques to fabricate nanomaterial-incorporated membranes for gas separation are valuable. This paper reviews the potential of using additive manufacturing in the fabrication of membranes incorporated with nanomaterials for gas separation.
