“…Graft modification has successfully been applied to tailoring of the membrane properties for certain applications (see the reviews, Charcosset, 1998;Klein, 2000;Nasef and Hegazy, 2004). Chemical or photochemical methods are mostly used, for example γ-ray irradiation to graft epoxy groups to glycidyl methacrylate GMA (Kim et al, 1991(Kim et al, , 1996Iwata et al, 1991;Kobayashi et al, 1993), or ultraviolet grafting of polyacrylic acid on polyethylene (PE) membranes (Kiyohara et al, 1997) to modify poly(ether sulfone) membranes (Taniguchi and Belfort, 2004;Pieracci et al, 1999), poly(ethylene terephthalate) PET membranes (Yang and Yang, 2003), or polypropylene (PP) membranes (Borcherding et al, 2003).…”
