Surface Modification Of Polyethersulfone Membrane Via Uv-Grafting for Forward Osmosis Technology

Surface Modification Of Polyethersulfone Membrane Via Uv-Grafting for Forward Osmosis Technology

In this study, UV-grafting was used in surface modification of polyethersulfone membrane (UFPES50) for forward osmosis (FO) application. Using two parameters, namely monomer concentration (acrylic acid) and grafting time, the modified membrane was characterised by attenuated total reflectanc...
