Abstract The modification of surface properties is necessary to improve the blood compatibility of polytetrafluoroethylene (PTFE). This paper describes the concept of a modification of PTFE surfaces. It consists of three steps: first, water vapour microwave plasma modification; second, acrylic acid vapour-phase post-grafting; and third, immobilization of the fibrinolytic protein urokinase. During or after each step, the modification results were characterized by zeta potential, ellipsometry… CONTINUE READING
