Electrochemical reversibly mirror device to control the electromagnetic radiation reflection.

"MIRROR DEVICE TO CONTROL reversible electrochemical reflection ELECTROMAGNETIC RADIATION". A reversible electrochemical mirror (REM) includes a first electrode (106) and a second electrode (110), one of which is substantially transparent. An electrolytic solution (112) disposed between the first and second electrodes contains ions (116) of a metal that can eletrodepositar electrodes depending on the applied potential. The electrolytic solution also contains halide anions and / or pseudo-halides having a total molar concentration ratio of at least 6: 1 compared to that of eletrodepositavel metal. It is usually necessary to apply a surface modifying layer (108) to the first electrode to ensure uniform nucleation to form a mirror eletrodeposito having high reflectivity is obtained.
