▎ 摘　　要

NOVELTY - Electrochromic device based on a hybrid tungsten trioxide/graphene oxide cathode and a transparent counter electrode indium tin oxide (ITO) on a flexible polymer substrate, contains at least two electrodes, one of which is optically transparent, and a closed space is formed between the electrodes, filled with an electrolyte (4) solution, where the electrodes transparent plates based on a flexible polymer were used, containing a conductive ITO coating (2) and an electrochromic layer of tungsten trioxide with graphene oxide. USE - The device is useful for creating device with an optically controlled level of light transmission for window openings of residential and domestic buildings, greenhouses and various light filters. ADVANTAGE - The device: is flexible electrochromic devices with electrically controlled optical light transmission value; and utilizes the elastic electrode, which ensures the flexibility. DESCRIPTION OF DRAWING(S) - The figure shows a schematic view of the electrochromic device with transparent flexible electrodes based on an electrochromic tungsten trioxide film. 1Terminals 2ITO coating 3ITO electrode 4Electrolyte
