Abstract
ⶠChemically cross-linked asymmetric P84® co-polyimide hollow fibre membranes with enhanced separation performance were fabricated using a dry-wet spinning process. ⶠInnovative in-line crosslinking was conducted by controlled immersion of the coagulated fibre in an aqueous diamine cross-linker solution before the take-up. ⶠThe effect of the cross-linker concentration on the thermal, mechanical, chemical and gas transport properties of the membranes was investigated.
