ABSTRACT:
A electromagnetic radiation modulating laminate comprises consecutively a conductive substrate, a persistent first metal layer, a fast ion conductor layer containing cations of a second metal, a transition metal compound ion storage layer, and an electrode. The transmission and reflection of electromagnetic radiation is modulated by the reversible dissolution and re-deposition of at least a part of the persistent first metal layer into and out from the fast ion conductor layer, upon the application of a reversible electrical potential across the conductive substrate and the electrode.
