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

A reflective dimming element in which a multi-layer membrane is formed within a transparent base material, wherein: the multi-layer membrane is configured such that transparent base material (10) which is sequentially formed with transparent electrode layer (20) and an ion storage layer (30), and transparent base material (70) which is sequentially formed with transparent electrode layer (60), a reflective dimming layer (50), and a catalyst layer (40) or is sequentially formed with the reflective dimming layer (50) and the catalyst layer (40) have a structure in which a non-water based hydrogen ion conductive electrolyte layer (90) is inserted between the ion storage layer (30) and the catalyst layer (40); and the electrolyte layer (90) is formed from a non-water based hydrogen ion conductive electrolyte solution (80) containing an ion-conductive polymer and exhibits high hydrogen ion conductivity and high light-transmitting performance. As a consequence, a reflective dimming electrochromic element that enables switching in a short time over a wide range via low-voltage driving and a dimming member using said element are provided.
