Polyurethane vascular catheter surface grafted with zwitterionic sulfobetaine monomer activated by ozone

Polyurethane (PU) is a conventional biomedical material with favorable biocompatibility and excellent mechanical properties and widely used in making vascular catheter, but its antithrombogenic property is not good enough to make it as a more demanding applicable biomaterial. Surface modification is...
