Polyethersulfone (PES) dope solutions were prepared from mixtures of two solvents containing N,N-dimethylformamide (DMF) as core solvent and acetone as co-solvent (CS) in a closed heating system. PES asymmetric membranes were cast by a dry/wet phase inversion process. Complete miscibility of PES wit...
