Abstract
, and it weakens the stability of the membrane, leading to a significant loss of selectivity during the separation of mixed gases. Thus, minimizing the disadvantages of polymer membranes is essential to ensure reliable gas-separation performance for practical applications. This feature article summarizes the theory underlying the plasticization of polymer membranes and introduces covalent and non-covalent approaches to suppress plasticization behaviour on a molecular level.
