In order to improve the hemocompatibility and antibacterial activity of polyethersulfone (PES) membranes,radiation grafting polymerization was used to graft hydrophilic sodiump-styrene sulfonate (SSS) on the surfaces of the membranes.Then,iodine and silver nanoparticles as antibacterial agents were introduced to the modified PES membranes to endow the materials with antibacterial property.The modified PES membranes were characterized by FT-IR,water contact angle,SEM and Zeta potential.The results showed that the 0.3g·mL-1 SSS concentration and the radiation dose of 15kGy were the optimum reaction conditions.Hemocompatibility and antibacterial tests indicated that the modified PES membranes had excellent hemocompatibility and antibacterial property.
