Covalent crosslinking has been shown to increase plasticization resistance in dense films by suppressing the degree of swelling and segmental chain mobility in the polymer, thereby preserving the selectivity of the membrane. This research focuses on extending the dense film success to asymmetric hollow fibers.Figure 4.9: Ternary phase diagrams of polymer, solvent, and non-solvent for spinning hollow fibers demonstrating how to obtain the binodal. Filled (red) and unfilled (partially red) circles represent 1 and 2 phase compositions achieved atanbsp;...
