摘要:
The present invention provides electrochromic layers, which comprise polymeric matrices with electrochromic solutions interspersed therein. Varying an electrical potential difference across a layer of the invention results in reversible variation in the transmittance of light across the layer because of electrochemical processes in the electrochromic solution of the layer. The invention further provides electrochromic devices, in which the electrochromic layers of the invention provide reversibly variable transmittance to light, and various apparatus in which the devices of the invention provide light-filtering or light-color modulation. Such apparatus include windows, including those for use inside and on the outside walls of buildings and in sunroofs for automobiles, and variable reflectance mirrors, especially rearview mirrors for automobiles.

An electrochromic device, such as a window or mirror, is disclosed that includes a transparent first substrate having an inner surface, a second substrate having an inner surface spaced apart from the inner surface of the first substrate so as to define a chamber therebetween, first and second electrodes carried on the inner surface of the second substrate and disposed thereon so as to be electrically isolated from one another, and an electrochromic medium disposed in the chamber between the inner surfaces of the first and second substrates. The electrochromic medium may be in solution-phase. Also, the electrodes may be disposed on the inner surface of the second substrate in substantially co-planar relation. Alternatively, the electrodes may be arranged in a stacked relation, with a layer of dielectric material provided therebetween. In this alternative configuration, the dielectric layer and the second electrode would include a plurality of apertures through which the electrochromic medium may contact the first electrode, which underlies the dielectric and second electrode layers. Also disclosed is an electrochromic device including a positive electrode, a negative electrode having a surface area different from the surface area of the positive electrode, and an electrochromic medium including cathodic and anodic species, wherein the ratio of cathodic to anodic species within the electrochromic medium is a function of the ratio of the surface areas of the positive and negative electrodes.
