MATERIAL COMPRISING A SINGLE FUNCTIONAL LAYER CONTAINING SILVER AND AN ABSORBENT LAYER
A material includes a transparent substrate coated with a stack of thin layers I including a lower coating including at least one absorbent layer, a single silver-based functional metal layer and an upper coating including at least one dielectric layer. The absorbent layer is separated from the substrate and from the functional layer by one or more dielectric layers. The material, once fitted in a double glazing, makes it possible to obtain a high selectivity, in particular of greater than 1.45, an interior and exterior light reflection of less than 25% and bluish hues in exterior reflection and in interior reflection.
Method for reducing or preventing the degradation of an antifouling layer or an optical article
The invention concerns a method for producing an optical article suitable for edging comprising an antifouling layer on which there is deposited a temporary overlayer for assisting with edging, comprising: depositing, on an optical substrate, an organic antifouling layer comprising at least a fluorinated polymer compound comprising hydrolysable functions; and depositing, on the antifouling layer, an overlayer for assisting with edging, of mineral nature, comprising one or more metal fluorides and/or one or more metal oxides or hydroxides; method characterised in that it further comprises a step of accelerated grafting of the antifouling layer chosen from: (a) a treatment of the deposited antifouling layer in a humid atmosphere of the deposited antifouling layer and (b) a catalytic treatment in the acidic or basic vapour phase of the deposited antifouling layer.
THIN FILM OPTICAL LENS AND METHOD FOR COATING A LENS
A thin film optical lens and method for coating an optical substrate serves to apply alternating layers, with varying thicknesses, of a high index dielectric material and a low index dielectric material on first and second surfaces of an optical substrate. The high and low index dielectric materials are layered through thin film deposition. The low index dielectric material is SiO.sub.2. The high index dielectric material is ZrO.sub.2 and/or Indium Zinc Oxide. The spectral results from application of high and low index dielectric materials reduce infrared radiation, block HEV light transmission, and reduce backside ultraviolet reflections, while also increasing visible (ultraviolet) light transmission through the optical substrate. Thus, the layering of dielectric materials on the first surface of optical substrate reflects up to 40% of the infrared radiation; and the second surface of optical substrate transmits up to 99% of ultraviolet light in the wavelength range between 300 to 400 nanometers.
SOLAR-CONTROL GLAZING
The present invention relates to solar-control glazings intended to be fitted in buildings, but also in motor vehicles. They comprise a glass substrate carrying a transparent multilayer stack comprising an alternation of n silver-based functional layers that reflect infrared radiation and of n+1 dielectric coatings, with n1, such that each functional layer is surrounded by dielectric coating. At least one of the dielectric coatings comprises a substantially metallic solar radiation absorbing layer based on Pd, enclosed between and in contact with two dielectric oxide layers of at least one element selected from Zn, Sn, Al, In, Nb, Ti and Zr.
Low-E matchable coated articles having absorber film and corresponding methods
A low-E coating has good color stability (a low E* value) upon heat treatment (HT). Thermal stability may be improved by the provision of an as-deposited crystalline or substantially crystalline layer of or including zinc oxide, doped with at least one dopant (e.g., Sn), immediately under an infrared (IR) reflecting layer of or including silver; and/or by the provision of at least one dielectric layer of or including an oxide of zirconium. These have the effect of significantly improving the coating's thermal stability (i.e., lowering the E* value). An absorber film may be designed to adjust visible transmission and provide desirable coloration, while maintaining durability and/or thermal stability. The dielectric layer (e.g., of or including an oxide of Zr) may be sputter-deposited so as to have a monoclinic phase in order to improve thermal stability.
Method for Preparing Optical Articles with Multi-layer Antireflective Coatings
The present invention is directed to a method for preparing a coated optical article including providing a non-conductive substrate; forming a conductive coating layer over the substrate; electrodepositing a first electrodepositable coating composition over the conductive coating layer to form a first electrodeposited inorganic coating layer; and electrodepositing a second electrodepositable coating composition over the first electrodeposited coating layer to form a second electrodeposited inorganic coating layer thereover, thereby forming a multi-layer antireflective inorganic coating over the conductive coating layer. Each of the first electrodepositable coating composition and the second electrodepositable coating composition is different one from the other, and each includes a sol prepared from a composition of a metal oxide precursor and protic acid such that each coating composition is hydrolyzed. Coated optical articles are also provided.
GLASS ARTICLES HAVING DAMAGE-RESISTANT COATINGS AND METHODS FOR COATING GLASS ARTICLES
A coated glass article and methods for producing the same are provided herein. The coated glass article includes a glass body having a first surface and a second surface opposite the first surface, wherein the first surface is an exterior surface of the glass body, and a damage-resistant coating formed by atomic layer deposition, the damage-resistant coating being disposed on at least a portion of the first surface of the glass body.
GLASS, GLASS-CERAMIC AND CERAMIC ARTICLES WITH PROTECTIVE COATINGS HAVING HARDNESS AND TOUGHNESS
An article includes: a transparent substrate having a primary surface; and a protective film disposed on the primary surface, such that each of the substrate and the protective film have an optical transmittance of 20% or more in the visible spectrum, and such that the protective film includes at least one of: (1) a hardness of greater than 13 GPa, as measured by a Berkovich nanoindenter, or (2) an effective fracture toughness (Kc) of greater than 2.5 MPa.Math.m.sup.1/2, as measured by indentation fracture at a depth of greater than 1 m.
Passivation of sulfide, oxide, and oxysulfide glass electrolyte films for lithium metal batteries
Certain glass, glass-ceramic, and ceramic electrolyte bodies formed from lithium or sodium sulfides and glass-forming sulfides, sulfoxides and/or certain glass-forming oxides provide good conductivity of lithium ions or sodium ions for use in lithium metal electrode or sodium metal electrode battery cells. The stability of the lithium or sodium metal anode-glass electrolyte interface is improved by forming a metal oxide passivation layer by atomic layer deposition on the facing surface of the electrolyte and activating the coating by contact of the passivated surface with the lithium or sodium electrode material.
LOW-E MATCHABLE COATED ARTICLES HAVING ABSORBER FILM AND CORRESPONDING METHODS
A low-E coating has good color stability (a low E* value) upon heat treatment (HT). Thermal stability may be improved by the provision of an as-deposited crystalline or substantially crystalline layer of or including zinc oxide, doped with at least one dopant (e.g., Sn), immediately under an infrared (IR) reflecting layer of or including silver; and/or by the provision of at least one dielectric layer of or including an oxide of zirconium. These have the effect of significantly improving the coating's thermal stability (i.e., lowering the E* value). An absorber film may be designed to adjust visible transmission and provide desirable coloration, while maintaining durability and/or thermal stability. The dielectric layer (e.g., of or including an oxide of Zr) may be sputter-deposited so as to have a monoclinic phase in order to improve thermal stability.
