Bioinspired polymeric heart valves derived from polyurethane and natural cellulose fibers

Toward mechanically robust self-healing polyurethanes using dynamics chemistry

“…Moreover, PUs are ideal materials for heart valves, but they also have some shortcomings such as poor biological stability and easy calcification, so it is necessary to regulate their composition to improve their properties. [130][131][132] PU fibers prepared by solution electrospinning are ideal functional materials for making drug-sustained-release and tissue scaffolds. 133 The development of tissue engineering technology not only solves the problem of insufficient blood vessel transplantation but also provides a new method for artificial skin transplantation.…”
