Abstract: A low-e insulating glass unit has a suspended, coated IR reflecting polymer sheet under tension, e.g. from heat shrinkage. The polymer sheet is coated with a multilayer stack of dielectric and metallic layers, including at least one silver layer deposited upon a zinc oxide seed layer that is at most 15 nm thickness. The use of zinc oxide ensures good seeding for high quality silver layer growth, thereby providing low emissivity. The thinness of the zinc oxide ensures that it resists cracking when the polymer sheet is tensioned.

Abstract: Durable-long lived plastic films (10) carrying sputter-deposited metal layer s (20 and 22) on both sides are disclosed. The slip side (14) of the plastic film is not preglowed. The nonslip side (18) is preglowe d. This combination of glowing and not preglowing leads to the desired long life.

Abstract: In a titanium nitride-based optical coating, the structural stability of the coating is enhanced by providing a damage-retardation base layer between the titanium nitride layer and a substrate. Where the optical coating is to provide solar control, the titanium nitride layer is selected primarily for achieving desired optical characteristics, while the thickness of the damage-retardation layer is selected primarily for achieving desired mechanical characteristics. The damage-retardation layer is formed of a grey metal, with nickel chromium being the preferred metal. The grey metal layer reduces the likelihood that the titanium nitride layer will crack. The tendency of such a layer to crack and form worm tracks is further reduced by exposing the substrate to a plasma preglow and/or by using a slip agent on the side of the substrate on which the layers are to be formed.

Abstract: A multi-layer antireflection coating is formed to include successive layers of a medium refractive index material, a high refractive index material, and a low refractive index material. The medium refractive index layer is hydrogenated in order to tailor the refractive index of the material to below 1.99 and to increase clarity in transmission. Preferably, the hydrogen atomic concentration is at least 7 percent, more preferably exceeds 9 percent, and most preferably exceeds 18 percent. The three layers combine to form a three-layer antireflection coating, but the hydrogenation may be used in antireflection coatings having a greater or lesser number of layers.

Abstract: A solar control member utilizes a combination of layers that include spaced apart titanium nitride layers to selectively transmit a higher percentage of visible light than near infrared energy, with a low visible light reflection. The titanium nitride layers are spaced apart by a distance that promotes optical decoupling with respect to occurrence of constructive and destructive interference of visible light propagating between the two titanium nitride layers. In one embodiment, the titanium nitride layers are spaced apart by a laminating adhesive layer. In another embodiment, the titanium nitride layers are formed on opposite sides of a substrate. The ratio of transmission at the wavelength of 550 nm to transmission at the wavelength of 1500 is at least 1.25. Each titanium nitride layer is sputter deposited. Care is taken to ensure that each layer does not become too metallic and to ensure that excessive oxygen is not incorporated into the layer. Thus, the nitrogen flow rate and the linespeed are controlled. Sputtering occurs at a fast rate using high powers and a minimum acceptable nitrogen flow, while minimizing background contamination.

Abstract: An improved way to impart antireflection properties to light transmissive substrates and, at the same time, achieve a durable surface and electrical conductivity is disclosed. A stack of at least two sputter-deposited light transmissive inorganic layers, one of which being electrically conductive and having a high index of refraction with the one above it (relative to the substrate being antireflected) having a low index of refraction, in combination with a thin lubricating overlayer comprising a solvent-soluble lubricant such as a solvent-soluble fluoropolymer can achieve this desired combination of properties.

Abstract: A solar control film having low visible light transmittance and low visible light reflectance is comprised of a first sheet of transparent substrate material having deposited thereon a solar-load-reduction film for preferentially reducing infrared light energy transmitted through the film, and a second sheet of transparent substrate material having deposited thereon a thin, transparent film of metal effective to partially block light transmittance, wherein the first sheet of transparent substrate and the second sheet of transparent substrate are separated by an optically massive layer that prevents the constructive and destructive interference of reflected light. A preferred embodiment of a solar control film includes, in order, a pressure-sensitive adhesive layer, a polyethylene terephthalate layer, a Fabry-Perot interference filter layer, an adhesive layer, a grey metal layer, another polyethylene terephthalate layer, and a hardcoat layer. The preferred solar control film provides wavelength selectivity in the infrared range while controlling visible light transmission and minimizing visual light reflectance.
