AbstractIn this study, effects of molecular weight distribution (M-d) on the performances of polyethersulfone (PES) ultrafiltration membrane were studied. PES samples with similar weight average molecular weight (M-w), number average molecular weight (M-n), or viscosity average molecular weight (M-eta) but different M-d, were obtained by blending. The thermodynamic and the kinetic factors were studied through ternary phase diagram and shear viscosity data, respectively. Experimental results showed that PES membranes with different structures can be obtained by blending. This can be due to the combined effects of the thermodynamic factor and kinetic factor of casting solution. The filtration experiments showed that wider M-d would lead to higher permeability and lower rejection when the M-n values of PES were similar, and on the other side, wider M-d could lead to lower permeability and rejection when the M-w values of PES were similar. In addition, under conditions of similar M-eta values of PES, the membranes showed similar performances irrespective of the M-d. (C) 2015 Elsevier B.V. All rights reserved.
