Abstract:
1. A process for manufacturing an electrochromic article comprising the following successive steps: (a) depositing a layer of electrochromic compound on a surface of a transparent or translucent electrically conductive substrate, (b) depositing a redox agent, which is a reducing agent or an oxidizing agent for the electrochromic compound, on the layer of electrochromic compound, (c) contacting the layer of electrochromic compound, deposited in step (a), and the redox agent, deposited in step (b), with a liquid electrolyte for a sufficient time to enable reduction or oxidation of the electrochromic compound by the redox agent, and (d) removing the electrolyte by rinsing and/or drying, the layer of electrochromic compound being a porous layer with open porosity and/or an electrically conductive layer.
