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.

Abstract: Tungsten trioxide (WO3) nanoparticles are synthesized via a sol-gel route using metallic tungsten as precursor and printed on a flexible electrode using inkjet printing in order to build solid-state electrochromic cells. A method for separate control of different spectral regions of the electrochromic device (near infrared and visible) is disclosed.
