Shape-memory polymers (SMPs) induced by heat or water are commonly used candidates for biomedical applications. Shape recovery inevitably leads to a dramatic decrease of Young's modulus due the enhanced flexibility polymer chains at transition temperature. Herein, principle phase-transition-induced stiffening shape-memory metallic alloys (SMAs) is introduced design molecular structures polyurethane (SMPUs), featuring all-hard segments composed main that attached with poly(ethylene glycol)...
Abstract Biodegradable shape memory polymers are promising biomaterials for stents used in minimally invasive surgical procedures such as intestinal stents. Herein, a series of biodegradable polyurethanes (SMPUs) containing novel phenylalanine‐derived chain extender (PHP) synthesized. Inspired by the fact that function biomacromolecules proteins is rich and varied because multiple combinations amino acid highly evolved biosystems, this study finds sequence distribution PHP SMPU will also...
We designed a shape memory polyurethane potentially used for vascular stents with water-induced stiffening in vivo and improved hemocompatibility.
