REFLECTIVE DIMMING ELECTROCHROMIC ELEMENT INSERTED WITH NON-WATER BASED HYDROGEN ION CONDUCTIVE ELECTROLYTE LAYER, AND DIMMING ELEMENT USING SAID REFLECTIVE DIMMING ELECTROCHROMIC ELEMENT

摘要

In a reflective dimming element having a multilayer film formed in a transparent base material, the multilayer film has a structure including a transparent base material 10 having a transparent electrode layer 20 and an ion storage layer 30 sequentially formed thereon; a transparent base material 70 having a transparent electrode layer 60, a reflective dimming layer 50 and a catalyst layer 40, or a reflective dimming layer 50 and a catalyst layer 40, sequentially formed thereon; and a non-water-based hydrogen ion conductive electrolyte layer 90 interposed between the ion storage layer 30 and the catalyst layer 40, while the electrolyte layer 90 is formed from a non-water-based hydrogen ion conductive electrolyte solution containing an ion conductive polymer and has high hydrogen ion conductivity and high light transmission performance. There are provided a reflective dimming electrochromic element which enables switching by low-voltage driving in a short time over a wide range, and a dimming member using the element.
