The specification discloses a method for making a curved, conductively coated glass member, and the resulting product, by providing for a sufficient degree of substoichiometry at the moment of bend that the glass can be bent using conventional bending techniques without crazing the coating. Two alternative methods for achieving the degree of substoichiometry are disclosed. One involves coating the part to an initial light transmittance (T.sub.o) which is lower than that typically sought by prior artisans. The other involves bending the part in a reducing environment. Also disclosed is a method for increasing conductivity of the coating by exposing the coated part to a reducing environment at temperatures considerably higher than those heretofore thought feasible for use in reduction curing.
The present invention relates to electrochromic mirrors and devices whose electrochromic element is composed of an electrochromic solid film and an electrolyte comprising redox reaction promoters and alkali ions and/or protons.
An electrochromic coating is produced by adding an organic moiety to a solution of an electrochromic precursor, said organic moiety having a decomposition temperature greater than, or a vapor pressure sufficiently low at, the temperature at which solution solvent is removed, such that said organic moiety remains integral with the electrochromic precursor coating on said substrate after said solvent evaporates, and said organic moiety having a decomposition temperature lower than, or a vapor pressure sufficiently high at, the temperature at which said electrochromic precursor coating is converted to an electrochromic coating that said moiety is substantially removed from said coating before or during said conversion.
The haze in a conductive tin oxide coating deposited on a substrate, particularly glass, can be reduced by applying, to a desired thickness, a solid-state coating, where the solid-state layer is applied as a precursor liquid to the tin oxide layer, is then dried and/or converted to a solid-state film overlying the conductive tin oxide film on the substrate.
A multiple-layer, high transmittance, low emissivity coated article which can be subjected to high temperature processing such as bending, annealing, tempering, laminating or glass welding as a result of titanium-containing primer layers is disclosed.
