Polysulfone gas separation hollow fiber membranes with enhanced selectivity
A recent paper dealt with the production of poly- sulfone hollow fiber membranes for gas separation [1]. It was suggested that increased shear during extrusion increases molecular orientation and, in turn, heightens selectivity. Molecular orientation in the membrane active layer was measured by infr...
