  • Patent number: 9383619
    Abstract: The present invention relates to a switchable infrared ray-visible ray reflection electrochemical mirror having high electrochemical stability and bistability, in which a stripping phenomenon of a metal thin film can be prevented and bistability can be improved through a process of increasing electrochemical stability of a reflective film from an electrode composition and an ionic liquid electrolyte composition having various compositions. In the proposed electrochemical mirror apparatus, since the metal thin film formed by electric reduction is not stripped from a transparent electrode through a surface treatment process, a more stable apparatus can be provided, and even though a voltage is not applied to the metal thin film, the thin film is prevented from being oxidized by using an optimized ionic liquid electrolyte, thus providing the effective electrochemical mirror apparatus where the metal thin film is continuously maintained.
