KI effects on the reversible electrodeposition of silver on poly(ethylene oxide) for application in electrochromic devices
A new approach to electrochromics, based on the reversible coating-dissolution of an oxide from an inorganic electrochromic electrolyte consisting of a silver–amine complex in a polymer electrolyte (PEO), has proven successful. The reversible electrodeposition of silver onto indium–tin oxide coated...

| description | A new approach to electrochromics, based on the reversible coating-dissolution of an oxide from an inorganic electrochromic electrolyte consisting of a silver–amine complex in a polymer electrolyte (PEO), has proven successful. The reversible electrodeposition of silver onto indium–tin oxide coated glass (ITO) was investigated and the influence of HClO
4 and KI was evaluated.
Several characteristics of the electrolyte Ag-PEO make it suitable for use in electrochromic reversible silver electrodeposition devices, such as visible absorption spectrum with an absorbance variation of 60%, an electrochromic efficiency of 5.2

The addition of perchloric acid improved the transparency of Ag-PEO, and potassium iodide (KI) was fundamental in setting up the process of reversible silver electrodeposition in the PEO polymeric matrix. A description of the electrochemical processes implied is presented. A number of approaches focusing on the improvement of system performance are tested. |
