Membrane gas separation plays a vital role in the protection of our environment and ensures sustainable growth of industries. The compromise between permeability and selectivity as explained by the Robeson’s upper bound minimized the number of commercial gas separation membranes. It unveiled the tailoring of new materials in the design of superior membranes. This review chapter explores the recent developments of membrane materials for various gas/vapor separation applications. © 2024 Elsevier Inc.
