An electrospun strong PCL/PU composite vascular graft with mechanical anisotropy and cyclic stability†
Abstract
A strong PCL/PU (polycaprolactone/polyurethane) vascular graft was fabricated using electrospinning. By regulating the content of PCL, the composite scaffolds show an obvious mechanical enhancement with strength up to 69.95 MPa. Furthermore, the scaffolds exhibit high porosity, mechanical anisotropy, cell compatibility and cycle performance, which are important for tissue engineering applications.
