Fabrication of defect‐free p84® polyimide hollow fiber for gas separation: Pathway to formation of optimized structure

The elimination of the additional defect healing post‐treatment step in asymmetric hollow fiber manufacturing would result in a significant reduction in membrane production cost. However, obtaining integrally skinned polymeric asymmetric hollow fiber membranes with an ultrathin and defect‐free selective layer is quite challenging. In this...
