New rigid polyimides with bulky CF 3 groups were synthesized and engineered into high‐performance hollow fiber membranes. The enhanced rotational barrier provided by properly positioned CF 3 side groups prohibited fiber transition layer collapse during cross‐linking, thereby greatly improving CO 2 /CH 4 separation performance compared to conventional materials for aggressive natural gas feeds.
