Patent

CA 2133755

Electrochromic devices applied to a substrate (12) are disclosed, including an electrochromic electrode layer (20), a counterelectrode layer (24), and an ion-conducting layer (22) sandwiched between those two layers and electrically isolating them from each other, in which the ion-conducting layer (22) is substantially uniform across the substrate and comprises an inorganic superstructure with associated organic material and with a microstructure which facilitates the transfer of ions. Methods for producing these devices are also disclosed, including depositing the ion-conducting layer (22) on the substrate (12) in the form of a solution, and effecting gelation of that solution.

L'invention se rapporte à des dispositifs électrochromes appliqués sur un substrat (12), et comportant une couche d'électrode électrochrome (20), une couche de contre-électrode (24) et une couche conductrice d'ions disposée en sandwich entre ces deux couches et les isolant électriquement l'une de l'autre. La couche conductrice d'ions (22) est essentiellement uniforme sur toute la surface du substrat et comprend une superstructure inorganique pourvue d'une matière organique associée et d'une microstructure qui facilite le transfert d'ions. L'invention se rapporte également à des procédés de fabrication de ces dispositifs, y compris des procédés pour déposer la couche conductrice d'ions (22) sur le substrat (12) sous la forme d'une solution, et des procédés pour effectuer la gélification de cette solution.
