    • The present invention provides improved 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.
    • 本发明提供了改进的电致变色层,其包含散布在其中的电致变色溶液的聚合物基质。 由于在层的电致变色溶液中的电化学过程,改变本发明的层之间的电势差导致穿过层的光的透射率的可逆变化。 本发明进一步提供了电致变色器件,其中本发明的电致变色层提供对光的可逆透射率,以及其中本发明的器件提供光过滤或光色调制的各种设备。 这种装置包括窗户,包括用于建筑物内部和外部墙壁以及用于汽车的天窗,以及可变反射镜,特别是用于汽车的后视镜。
