Separation of CO2/CH4 and O-2/N-2 by polysulfone hollow fiber membranes: effects of membrane support properties and surface coating materials

n this study, six different types of polysulfone hollow fiber membranes were fabricated from the same polymeric dope solution by manipulating several important parameters during the spinning process, aiming to find the best membrane supports for the coating layer in the gas separation process. The e...
