Abstract
Polyurethane surface was chemically modified to have different hydrophilic polyethyleneoxide(PEO)/hydrophobic dodecanediol(DDO) groups and negatively charged sulfonate group to investigate the effect to the antithrombogenicity. The hydrophilicity of the surface was significantly increased after PEO grafting or sulfonation. Lowering in-vitro platelet adhesion led to a prologation in the ex-vivo occlusion time. Especially, the sulfonated PU-PEO surface showed most enhanced blood compatibility due to the synergistic effects of PEO and
