Suppression of plasticization in polysulfone membranes for gas separations by heat-treatment technique
polysulfone (Udel P1700). Two types of membranes with heat treated and untreated were prepared to study the effect of heat-treatment process on its permeation properties. For untreated membrane, CH4 permeation rate remained almost constant with applied gas pressure. CO2 permeation rate exhibited an...
