Abstract

New rigid polyimides with bulky CF₃groups were synthesized and engineered into high-performance hollow fiber membranes. The enhanced rotational barrier provided by properly positioned CF₃side groups prohibited fiber transition layer collapse during cross-linking, thereby greatly improving CO₂/CH₄separation performance compared to conventional materials for aggressive natural gas feeds.
