Influence of surface modifying macromolecules (SMMs) on polyethersulfone hollow fiber membranes for water separations

The objective of this work is to modify the polyethersulfone (PES) hollow fiber membranes by blending with Surface Modifying Macromolecules (SMMs) which were able to introduce charges at the membrane surface. To study the effects of SMMs, PES solutions with and without blending SMMs were spun by the...
