摘要: PCL-based shape memory polyurethane ionomers with quaternarized pyridine moieties incorporated through molecular extension were synthesized. These polyurethanes specifically designed as low-temperature thermoplastic anti-bacterial orthotic materials. A commercialized material was employed for comparison. The influence of ionic groups on the properties materials studied. and cytotoxicity ionomer tested. It found that, different from other researchers' conclusions, Coulombic force among cationic increased cohesion hard segments after ionization could lead to better phase separation, soft segment crystallability stability. results this work indicated although group had function improving asymmetric extender a negative effect Several main physical prope...
