Abstract(#br)A defect-free membrane with a very high gas permeance is greatly attractive to both academia and industry. Thin film composite (TFC) membranes are promising candidates. However, it is always challenging to have a reproducible and up-scalable method to fulfill the needs. Herein, we report a novel and straightforward strategy to fabricate a high-performance hollow fiber composite membrane using a crosslinked polydimethylsiloxane (PDMS) with a high inherent viscosity obtained from a novel post-crosslinking method.

Abstract(#br)The invention of polymers of intrinsic microporosity (PIMs) has opened up great opportunities for the developments of high-performance composite membranes which possess both high gas permeance and selectivity. However, it still remains challenging to translate such PIM materials into PIM-related composite membranes with characteristics of high permeance and selectivity.
