| 中文摘要 | we described a two-step process to fabricate the heparinized polypropylene (pp) film using cyanuric chloride (cc) as a trifunctional reagent and poly (ethylene glycol) methacrylate (pegma) as a spacer. the modified pp films were characterized by attenuated total reflectance ft-ir and x-ray photoelectron spectroscopy; the content of pegma and heparin were determined by gravimetric method and a toluidine blue assay, respectively. for the pp-g-pegma films, it was found that small size protein bsa tended to adsorb on the surface of low molecular weight monomer grafted pp, whereas big spindle-shaped fibrinogen tended to adsorb on the surface of high molecular weight monomer grafted pp. we gave a definition of anti-protein adsorptive factor r with two model proteins, albumin and fibrinogen. the results by platelet adhesion and plasma recalcification time (prt) experiments indicated that the factor r could be used to quantitatively evaluate the anticoagulant tendency of pp-g-pegma modified films. for the pp-g-pegma-g-heparin modified films, the surface was proved to have a high bioactivity by the adsorption of at iii assay and very low platelet adhesion. it indicated that immobilization of heparin on the pp film with pegma as a spacer was an effective way to improve the hemocompatibility of pp. crown copyright (c) 2012 published by elsevier b.v. all rights reserved. |
