“…Saito's group (Asai et al, 2005;Hagiwara et al, 2005;Kim and Saito, 2000;Kiyohara et al, 1997;Kubota et al, 1997a;Miyoshi et al, 2005;Okamura et al, 2002;Ozawa et al, 2000;Saito et al, 1999;Sasagawa et al, 1999;Tsuneda et al, 1998) prepared affinity and ionexchange membranes (IEMs) by the RIGP method and subsequent chemical modifications. Radiation creates radicals throughout the trunk polymer because of its high energy.…”

Membrane technologies have now been widely exploited and utilized on a large scale due to the unique separation principles of membranes. For further progress, however, membranes with favorable properties and functionabilities must be designed and prepared. Based on existing membrane materials, modification of them is necessary. Among different technologies, graft polymerization is a universal modification method for preparing a "tailored" membrane surface with desired functions. The grafted polymer chains on the membrane surface play an important role in membrane applications. In this chapter methods of graft polymerization on the membrane surfaces and the relative applications are introduced.

“…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).…”

The rapid development of proteomics has been made possible primarily by the progress in analytical and preparative separation methods. Biological systems are so complex that the separation procedures employed must be highly efficient as well as highly selective. The latter requirement is best met by affinity separations based on molecular recognition. The present review critically discusses the properties of the affinity sorbents employed in proteomics, namely, agarose gels, dextrans, modified methacrylate and acrylamide polymers, porous and nonporous silica, porous glass beads, monoliths, affinity membranes and magnetic beads. The physico-chemical properties of these materials, their preparation, application, approaches to their modification and their relative advantages and drawbacks are discussed.

“…Kim et al 84 prepared a porous hollow-fiber membrane, containing L-phenylalanine as a pseudo-biospecific ligand, by radiation-induced grafting of glycidyl methacrylate onto polyethylene microfiltration hollow fibers, followed by coupling of the epoxide group produced with L-phenylalanine. A scheme for the coupling of the ligands to a porous polyethylene membrane was developed by w x Kiyohara et al 112 . Two methods were employed for the introduction of activated groups, i.e., succinimide and epoxy groups, into a porous polyethylene hollow fiber by Ž .…”
