The effect of the nature of the pore-forming agent (polyethylene glycol, ethylene glycol, diethylene glycol, glycerol) on the structure and performance of hollow fiber membranes spun from polysulfone solutions in N,N-dimethylacetamide was studied. The membranes have been characterized using various methods (determination of gas permeability and water entry pressure, scanning electron microscopy, contact...
In relation to the demand for asymmetric porous hollow fiber membranes to be used in gas–liquid membrane contactors designed for operation in organic media, polysulfone membranes of this type have been prepared and subsequently modified to impart oleophobic properties to their surface. The structure and properties of the membranes have been characterized using various techniques, such as optical and...
