To develop a small-diameter vascular graft that closely mimics natural blood vessels and improves biocompatibility.
Developed a PU elastomer with enhanced properties
Fabricated a composite graft using bacterial cellulose and PU microfibers
Evaluated graft performance in simulated physiological fluids
The graft exhibited excellent elastic stability
Increased hydrophilicity, hemocompatibility, and cytocompatibility
Promoted expression of CD31 and VEGF, enhancing endothelial cell functions
