Abstract[English]
The present application relates to a process of preparing a shape-memory crosslinked liquid crystal elastomers film, the process comprising the steps of pre-crosslinking a liquid crystal oligomer mixture comprising a liquid crystal oligomer, a crosslinker, and initiators under a first stimulus; deforming the pre-crosslinked oligomer mixture; and crosslinking the deformed oligomer mixture under a second stimulus. The present application also relates to a liquid crystal oligomer mixture to make a shape-memory crosslinked liquid crystal elastomers film.[French]
La présente demande concerne un procédé de préparation d'un film d'élastomères à cristaux liquides réticulés à mémoire de forme, le procédé comprenant les étapes de pré-réticulation d'un mélange d'oligomères à cristaux liquides comprenant un oligomère à cristaux liquides, un agent de réticulation et des initiateurs sous un premier stimulus ; la déformation du mélange d'oligomères pré-réticulé ; et la réticulation du mélange d'oligomères déformé sous un second stimulus. La présente demande concerne également un mélange d'oligomères à cristaux liquides pour fabriquer un film d'élastomères à cristaux liquides réticulés à mémoire de forme.
