Abstract

Polyurethane was synthesized by the copolymerization with isocyanate and diols. The structure and properties of the copolymers were characterized by infrared spectrometer (IR), differential scanning calorimetry (DSC) and thermogravimetry (TG). The rabbit blood samples was dripped on the polyurethane, which was prepared by drying and die, and the contact angle was measured by contact angle measurement, then infiltration phenomenon was observed by electron microscopy. The results showed that the contact angle of blood samples and polyurethane was decreased with increasing time, and the platelets on the polyurethane would gradually increase and more rules. Thus the polyurethane coating had good hydrophilic property and anticoagulant activity.
