Effect Of Polymer Concentration On Development Of Asymmetric Polyethersulfone Membrane For Gas Separation
Asymmetric polyethersulfone (PES) membranes were fabricated through a simple dry/wet phase inversion process. Casting solution developed in this study consisted of polyethersulfone, 1-methyl –2- pyrolidone (NMP) and distilled water. The casting solution was cast using pneumatically-controlled cast...
