摘要:
The subject of the invention is an electrically controllable system having variable light scattering and/or transmission, comprising a functional film (1, 21) provided with electrically conducting layers (2, 3, 22, 23), the said film having active elements in the form of polarizing particles, or of liquid crystals associated with dichroic dyes, and in suspension in a medium. The said system is provided with one or more means preventing/compensating for degradation by photoreduction of at least some of the active elements, especially degradation of the dichroic dyes and/or that of the polarizing particles.
摘要:
The invention relates to an electrochromic glazing successively comprising a glass sheet, a first electrode constituted by a transparent electroconductive layer, whose square resistance is below 5 Ohms, a layer of a cathodic electrochromic material, an electrolyte, a layer of an anodic electrochromic material and a second transparent electroconductive electrode, barrier layers being inserted between the said electrodes and the said electrochromic material layers, the square resistance of the assembly formed by an electrode and its barrier layer being below 5 Ohms.
