Title
(EN) LIQUID CRYSTAL ELASTOMERS
(FR) ELASTOMERES A CRISTAUX LIQUIDES
Abstract
(EN)
This invention describes a method for the loading and alignment of elastomers in electro-optic and electro-active devices. It comprises the in-situ polymerisation between substrates of liquid crystal monomers in the presence of cross-linking reagents. It also describes the production of free-standing elastomer films.
(FR)
Cette invention concerne un procédé permettant de charger et d'aligner des élastomères dans des dispositifs électrono-optiques et électro-actifs. Ce procédé comprend la polymérisation in-situ entre des substrats constitués de monomères de cristaux liquides en présence d'agents de réticulation. Cette invention concerne également la production de films élastomères autostables.
