  • Electrochromic device and method for producing same
    Patent number: 8773747
    Abstract: The present invention relates to electrochromic devices and methods for functionalizing cellulose-based materials, in production and post-production stages, in order to obtain solid-state electrochromic devices. The invention is in the field of electrochemistry. These functionalized cellulose-based materials have typical electrochromic characteristics, specifically the capacity to change the oxidation state, leading to a modification of the physical properties, shown by a color change when exposed to an electric potential difference, being this color change reversible. The color remains in the absence of any electric stimulus, demonstrating a memory effect.
    Type: Grant
