Catheter model tubes were prepared from a medical-grade polyetherurethane and their outer surfaces modified by surface-graft polymerization of acrylamide and dimethyl acrylamide (DMAA). The surface-graft layer was characterized by means of dry staining, scanning electron microscopy (SEM), X-ray photoelectron spectroscopy, and protein adsorption. Ex vivo evaluation for the blood compatibility of the surface-modified polyurethane was carried out using the polyurethane tube as an arterio-venous… CONTINUE READING
