Decoding molecular weight effects in polyimide membranes for CO 2 /CH 4 separation: bridging experiments and simulations

Nesrin Özenir, Mütesir Temel, Tuba Erdoğan-Bedri, Sadiye Velioğlu

Molecular simulations and experiments reveal that higher M w of 6FDA-based polyimide membranes enhances polymer chain packing and CO 2 solubility despite reduced free volume, driving superior selectivity for natural gas upgrading applications.
