Abstract
A tape that includes an electronically conductive flexible substrate, a release layer, and an adhesive comprising an ion-intercalating material, and electrochromic devices and glazing units prepared using this tape.
Claims28
A tape comprising an electronically conductive flexible substrate, a release element selected from the group consisting of removable release layers and low surface energy coatings, and an adhesive comprising an ion-intercalating material,
- wherein when the adhesive of said tape is laminated to a second electronically conductive substrate comprising a second ion-intercalating material to form an electrochromic device, the device is capable of undergoing a visible change in transmission or reflectance upon application of a voltage.
A method of assembling an electrochromic device comprising the steps of:
- (a) providing a tape comprising an electronically conductive flexible substrate, a release element selected from the group consisting of removable release layers and low surface energy coatings, and an adhesive comprising a first ion-intercalating material;
- (b) contacting a second electronically conductive substrate comprising a second ion-intercalating material with the adhesive of said tape,
- one of said ion-intercalating materials comprising an electrochromic material and the other of said ion-intercalating materials comprising an ion-storage material;
- and
- (c) laminating said tape and said second electronically conductive substrate together.
An electrochromic device comprising an ion-intercalating electrochromic material and an ion-intercalating ion-storage material separated by an ion-conducting electrolyte and disposed between (a) a rigid, electronically conductive substrate comprising (i) a rigid layer and (ii) a transparent electronic conductor deposited on said rigid layer and (b) a flexible, electronically conductive substrate,
- at least one of said electrochromic material, said ion-storage material, and said electrolyte being provided in the form of an adhesive.
A glazing unit comprising:
- (a) an electrochromic device comprising an ion-intercalating electrochromic material and an ion-intercalating ion-storage material separated from each other by an ion-conducting electrolyte,
- at least one of said electrochromic material, said ion-storage material, and said electrolyte being provided in the form of an adhesive,
- said device being disposed between (a) a rigid, electronically conductive substrate comprising (i) a rigid layer and (ii) a transparent electronic conductor deposited on said rigid layer and (b) a flexible, electronically conductive substrate, both of said substrates being electronically conductive;
- and
- (b) a second rigid, transparent substrate adjacent said flexible transparent substrate.
