Abstract:
In this study cationic and heparinized polyurethanes (PUs) were synthesized by a two-step solution polymerized method. Cationic and heparinized PUs were investigated by infrared spectroscopy, electron spectroscopy for chemical analysis (ESCA) and turbidity method. At the same time, the PUs proved of good biocompatibility through the laboratory tests, including blood coagulation time (CT), activated partial thromb plastin time (APTT) and fibroblast culture. These materials have good biocompatible function.
