| 中文摘要 | polypropylene (pp) was modified with 2-hydroxyethyl acrylate (hea) by solution radical grafting to introduce active hydroxyl groups on polypropylene backbone (pp-g-hea). then the biomimic monomer, 2-methacryloyloxyethyl phosphorycholine (mpc), was grafted onto the surface of pp-g-hea film (pp-g-hea-g-mpc) by redox graft polymerizations with ceric(iv) ammonium nitrate as an initiator. fourier transform infrared spectroscopy (ftir) and x-ray photoelectron spectroscopy (xps) showed that the hea and mpc were introduced onto pp molecular chains and the copolymer, pp-g-hea-g-mpc were formed. the water contact angle measurements demonstrated that the final modified pp film exhibited a better hydrophilic surface compared to the neat pp film. the platelets adhesion on the neat pp, pp-g-hea and pp-g-hea-g-mpc film was examined by scanning electron microscopy (sem). it was found that a large number of platelets were adhered and activated on the surface of neat pp and pp-g-hea films, while the number of platelets on pp-g-hea-g-mpc surface was decreased remarkably. the result revealed that the introduction of poly(mpc) onto the pp surface improved the hemocompatibility of pp substantially.
