Graft polymerization can be initiated by various methods, for example, UV, high energy(γ- ray, e-beam), plasma, chemical initiators and oxidation of polymers. Among them, radiation-induced graft polymerization is a well-known method for modification of the physicochemical properties of polymeric materials, and is of particular interest for achieving specifically desired properties as well as excellent mechanical properties. Radiation-induced graft polymerization can be classified based on three factors, (a) Irradiation source, (b) Irradiation opportunity, and (c) Monomer phase (vapor of liquid phase). In this study, graft copolymerization of Glycidyl methacrylate(GMA) to the polypropylene(PP) fabric with UV radiation source in vacuum was carried out in vapor phase with benzophenone (BP) as an photo initiator and then followed by the subsequent functionalization with chlorosulfonic acid and diethylamine. We confirmed a change of mean pore diameter according to the degree of grafting and functionalization condition, and after we investigated γ-globulins adsorption properties by pH and adsorption time using membrane, which were synthesized, examined optimum adsorption condition. |
