S. Belfer et al., SURFACE MODIFICATION OF COMMERCIAL COMPOSITE POLYAMIDE REVERSE-OSMOSIS MEMBRANES, Journal of membrane science, 139(2), 1998, pp. 175-181
Radical grafting of two monomers, methacrylic acid and polyethylene gl
ycolmethacrylate, onto commercial composite polyamide reverse osmosis
membranes was performed. A redox system was used for initiation, and g
rafting was performed in an aqueous medium at room temperature. Surfac
e grafting was characterized by ATR-FTIR, ESCA and streaming potential
measurements. It was found that the membranes were surface modified w
ithout damage to their transport properties. (C) 1998 Elsevier Science
