Preparation of semi-alicyclic homo- and blended polyimide membranes using alicyclic dianhydrides with kink structures and their gas separation properties

Chae-Hee Seo et al.

Summary: Two soluble semi-alicyclic polyimides were synthesized and their homo-and blended membranes were prepared. The experimental results show that these membranes have potential in gas separation and exhibit comparable performance to commercial membrane materials.

The effect of chain rigidity and microstructure on gas separation performance of the cardo-based polyimides

Xiaohua Tong et al.

Summary: In this study, a series of aromatic polyimides based on Cardo structure were synthesized using different building blocks and commercially available dianhydride. The resulting polyimides exhibited excellent thermal stability and good mechanical properties. Single gas permeation tests revealed that one of the polyimides showed higher permeability without sacrificing selectivity, while another polyimide showed significantly improved CO2 permeability and CO2/CH4 selectivity. These findings provide guidance for the molecular structure design of gas separation membranes.

Self-crosslinking of bromomethylated 6FDA-DAM polyimide for gas separations

Shan Xu et al.

Summary: A high-performance crosslinked brominated 6FDA-based polyimide membrane was developed by tuning the permeability and selectivity through introducing bromine atoms into the polyimide structure. The crosslinking reaction greatly stabilized the membrane performance against plasticization under high CO2 feed pressure. This study provides a facile approach for the preparation of high-performance gas separation polymeric membranes with enhanced plasticization resistance.
