In this study, γ-cyclodextrin (γ-CD) based MMMs were synthesized via a simple solution casting method. γ-CD could be molecularly dispersed in Matrimid matrix up to 3 wt% loading without defects at the interfaces in membranes. ATR-FTIR results showed that γ-CD based MMMs have significant peak with loading increases.

This demonstrates that the incorporation of γ-CD in Matrimid membrane significantly improves both permeability and selectivity.

Small Angle X-ray scattering reveals a distinct phase separation pattern within the AIEM matrix, which is due to the introduction of sulfonates to increase the hydrophilicity of the side-chains.
