Low-Emissivity Coatings

摘要

Embodiments of the present invention include low emissivity (low-E) coatings and methods for forming the coatings. The low-E coating comprises a self-assembled monolayer (SAM) on a glass substrate, where one surface of the SAM is disposed in contact with and covalently bonded to the glass substrate, and one surface of the monolayer is disposed in contact with and covalently bonded to a metal layer. In some embodiments, the low-E coating comprises an assembly of one or more monomeric subunits of the following structure: Si—(CnHy)-(LM)m where n is from 1 to 20, y is from 2n-2 to 2n, m is 1 to 3, L is a Group VI element, and M is a metal, such as silver. In some embodiments, (CnHy) can be branched, crosslinked, or cyclic. The coating can further comprise an antireflection coating on the metal layer.
