(EN) PROCESSABLE, TUNABLE THIOL-ENE CROSSLINKED POLYURETHANE SHAPE MEMORY POLYMERS
(FR) POLYMÈRES À MÉMOIRE DE FORME DE TYPE POLYURÉTHANE RÉTICULÉS PAR UN THIOLÈNE TRAITABLES, AJUSTABLES
Abstract
(EN) An embodiment includes a platform shape memory polymer system. Such an embodiment exhibits a blend of tunable, high performance mechanical attributes in combination with advanced processing capabilities and good biocompatibility. A post-polymerization crosslinking synthetic approach is employed that combines polyurethane and thiol-ene synthetic processes. Other embodiments are described herein.
(FR) Selon un mode de réalisation, cette invention concerne un système de polymères à mémoire de forme pour plateforme. Ce mode de réalisation présente un mélange d'attributs mécaniques de haute performance, réglables en combinaison avec des capacités de traitement évoluées et une bonne biocompatibilité. Une approche de synthèse à réticulation post-polymérisation qui combine des procédés de synthèse de polyuréthane et de thiolène est utilisée. D'autres modes de réalisation sont décrits dans la présente.
