SWITCHABLE MIRROR ELEMENT, AND SWITCHABLE MIRROR COMPONENT AND INSULATING GLASS EACH INCORPORATING THE SWITCHABLE MIRROR ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a reflective light control (switchable mirror) element that can be switched to a transparent state that is nearly completely colorless and provides a high optical transmittance, and to provide a switchable mirror component and an insulating glass each using the switchable mirror element. SOLUTION: The switchable mirror element includes a switchable layer 10 having a chromic property enabling the switchable layer to be reversibly changed between a transparent state by hydrogenation and a mirror state by dehydrogenation, and a catalytic layer 20 promoting hydrogenation or dehydrogenation in the switchable layer 10. The switchable layer 10 includes an alloy of magnesium with one or more metals from calcium, strontium and barium. COPYRIGHT: (C)2010,JPO&INPIT
