Abstract

The present disclosure relates a polymer dope comprising a polysulfone (PS) polymer substantially dispersed in a solvent composition comprising at least one organic solvent and at least one non-solvent additive, wherein the amounts of organic solvent and non- solvent additive are selected to enable the PS polymer to be present in about 30% to about 60% by weight based on the total weight of the polymer dope. The present disclosure further relates to a method of using the polymer dope to fabricate a polymer membrane, and use of the same in gas separation.
