Cyclodextrin-based supramolecular assemblies derived from poly(dimethylsiloxane) (PDMS) functionalized polyrotaxanes (PRXs) were self-assembled into core-shell morphologies and used as soft nanoparticle (SNP) additives in the selective layer of thin film composite (TFC) membranes for the first time. Various weight percentages (wt%) of the PRX SNP additives were combined with Pebax® 2533 to form the selective layer, and the gas transport properties of the TFC membranes were studied in detail. Increasing the amount of PRX SNP additives led to a significant increase in CO2 permeance of the membranes, with only a slight decrease in the CO2/N2 selectivity, which was attributed to the dynamic natu..View full abstract
