Abstract:Polyetherimide (PEI) with good heat stability, corrosion resistance and chemical stability is considered as an excellent material for membrane preparation. By the way of cloud-point titration, it is found that the sequence of nonsolvent additives (NSA) coagulation ability is as follows: γ-GBL2O. Flat ultrafiltration (UF) Polyetherimide membranes were prepared by the dry/wet phase inversion method, with N, N-dimethyl-acetamide (DMAc) as a solvent, and water as a coagulant. Considering the water flux and Bovine Serum Albumin (BSA) rejection ratio, γ-GBL and BuOH are the most suitable additives for membranes preparation.
