Abstract
Sugar-based amphipathic compounds (BA-CnAG) were successfully prepared. Polyurethane (PU) was grafted with glycidyl methacrylate (GMA) by the means of UV irradiation, and further modified with the BA-CnAG based on the ring opening of the epoxy groups. The surface graft polymerization was confirmed by ATR-FTIR and XPS. Water contact angle, protein adsorption, and platelet adhesion measurements were used to evaluate the hydrophilicity and hemocompatibility of the films. The results demonstrated that amphiphilic surfactant-containing polymer surfaces presented protein-resistant behavior and anti-platelet adhesion after functionalization with BA-CnAG. Besides, the hemocompatibility of the modified surface deteriorated as the length of hydrophobic chain of BA-CnAG increased.
