Conductive busbars and sealants for chromogenic devices

摘要

This invention discloses conductive busbars and sealants for electrooptic devices including electrochromic mirrors and windows. The conductive busbars are formed from materials comprising nanoparticles, and the sealants comprise of additives that promote a two phase morphology and use of adhesion promotion additives with crosslinkers. Methods to deposit busbars and then to connect these busbars to electrical connectors are also disclosed.

主权项

1. An electrooptic variable reflectance mirror for vehicles comprising front and rear spaced elements, each of the said elements having a rear surface and a front surface, said rear surface of the front element having a layer of transparent conductive coating disposed thereon, and said front surface of said rear element comprises at least one layer of conductive coating, wherein the said transparent conductive coating or said conductive coating comprises of a zinc oxide coating doped with at least two additional metal oxides, where the front and the rear elements are sealably bonded together in a spaced apart relationship and define a chamber there between, said chamber comprising an electrooptic medium, and wherein at least one of the rear surface of the said front element and the front surface of the said rear element has a conductive busbar deposited on its perimeter or a portion of its perimeter wherein the said busbar is formed of a composite comprising conductive nanoparticles in an organic matrix, or the said busbar is formed by deposition of nanoparticles from a suspension of the said nanoparticles in a fluid.
