Why polyether polyurethane has good blood compatibility

Strong hydrolyzability.

Polyether polyurethane has good blood compatibility due to strong hydrolyzability. Polyurethane is widely used as cardiovascular biomaterials because of its good blood compatibility and mechanical properties. Polycarbonate-based polyurethane has been used to replace more

Traditional biomedical polyether polyurethanes, because of their antioxidant biodegradability, exhibit a two-phase microstructure due to the thermodynamic incompatibility between hard and soft segments, i.e. microphase separation, microphase separation

Resulting in high deformability and mechanical strength of the material.
