Electrochromic device and a method to manufacture the same
First Claim
1. An electrochromic optical device comprising a first substrate, a first transparent conductor on one side of said first substrate, a first electrochromic layer on the side of said first transparent conductor opposite said first substrate, a second substrate, a second transparent conductor on one side of said second substrate, a second electrochromic layer on the side of said second transparent conductor opposite said second substrate, the two substrates with their respective sides carrying the respective transparent conductors and electrochromic layers facing each other and being laminated to each other by means of a solid state polymeric material doped with a metal salt said metal salt being selected from the group consisting of LiClO4, NaCF3 SO3, LiCF3 SO3, LiSCN and NaSCN, said metal salt being capable of working as an ion conductor, wherein the ion conductor comprises a poly(methylmethacrylate) and a polyether.

Abstract
Electrochromic optical device and method to produce the same. The device includes first substrate (1) on the one side of the substrate a first transparent conductor (2) on the conductor a first electrochromic layer (3), a second substrate (4), on the one side of the second substrate a second transparent conductor (5), on the second transparent conductor, a second electrochromic layer (6), the two substrates are laminated to each other by means of a solid state polymer with their sides carrying the respective transparent conductor and electrochromic layer facing each other. The polymer work as an ion conductor and is based on methylacrylate and poly(propyleneglycol) doped with a metal salt.
