摘要： The invention relates to a multilayer structure for an electrochromic cell, to a electrochromic cell and an ophthalmic device incorporating the multilayer structure, to corresponding uses of the multilayer structure, and to methods for manufacturing the multilayer structure, the electrochromic cell and the ophthalmic device.
The multilayer structure comprises:
- a transparent flexible substrate (30) comprising a thermoplastic polymeric film (39), the flexible substrate (30) having two main surfaces, at least one of which is configurated to be a barrier (38) to at least one of oxygen, water vapor and solvents, and
- at least one electrically conductive layer (31) which surmounts the flexible substrate (30) to form a flexible first part of the electrochromic cell, the at least one electrically conductive layer (31) being configured to form an electrode of the electrochromic cell and comprising a deformable electrically conductive nanostructure.
According to the invention, said flexible first part is formed to a curved shape (34) defined by a first curvature including at least one of a cylindrical, toric and spherical curvature.

摘要： The present invention relates to a process for manufacturing an electrochromic article, comprising the following successive steps: (a) deposition of a layer of an electrochromic compound on the surface of a transparent or translucent electroconductive substrate; (b) deposition of a redox agent, which is a reducing agent or an oxidizing agent for the electrochromic compound, on the layer of electrochromic compound at a multitude of discrete points or areas thereon; (c) bringing the layer of electrochromic compound, deposited in step (a), and the redox agent, deposited in step (b), into contact with a liquid electrolyte for a time long enough to allow the electrochromic compound to be reduced or oxidized by the redox agent; and (d) elimination of the electrolyte by rinsing and/or drying, the layer of electrochromic compound being a porous layer of open porosity and/or an electrically conductive layer.

摘要： The invention relates to a transparent electroactive system that includes two electrodes (2, 3) juxtaposed on the same side of a closed space (12) containing electroactive substances. The two electrodes are separated by a distance of less than 250 μm, and a barrier (1) extending towards the inside of the closed space is placed between the electrodes. The separation between the electrodes is thus not visible, and a mutual neutralisation between the electroactive substances is prevented. Advantageously, the electroactive substances are contained in cells (5) separated from each other within the closed space. The barrier (1) can thus be distinct from separation walls (4) between the cells, or can be assimilated with some intercellular walls.
