原始语种摘要: The gas separation process by asymmetric polymeric membranes has received much attention during the last decades becauseof its more energy efficiency than other conventional separation processes. Hollow fibers are the most favored membranegeometry owing to their high surface area per unit volume of membrane module. One of the key elements determining thepotential and applications of asymmetric hollow-fiber membranes are the structural properties mainly including pore size,pore distribution, selective layer thickness, molecular orientation and defectiveness. These elements can generally varydepending on conditions during dry-jet wet-spinning process. Flow conditions in spinneret during extrusion are known toaffect the dense-layer of hollow fibers and possibly to enhance separation...
