Highlights
- Stable rigid monomers result in polyimides with higher Mw, Tg, TR, and the more superior separation performance.
- Thermal rearrangement improved ideal gas separation by 1.5 to 2.0 orders of magnitude.
- Thermal rearrangement resulted in an enhanced thermal, mechanical and chemical properties of the produced membranes.
Polymeric membranes remain and will most likely continue to be the most practical cost-effect chemical constructs for gas separation processes, provided that novel polymers are developed to overcome current and persisting limitations facing exiting membranes. Here, we report a methodical and systematic study of the structure-property-function relations of standard polyimide membranes and their implications …
