Inorganic stannic oxide polymers are provided which are comprised of a major portion of repeating units of the formula
IN WHICH AT LEAST ONE OF THE GROUPS R1-R4 is -OH or -O- and at least one of the groups R1-R4 is an anion of a water soluble salt of tin (IV) such as a chloride, bromide, nitrate, sulfate anion etc., with the remainder of the groups being -OH, -O- or an anion as defined above and a minor portion of repeating units of the formula
WHEREIN M1 is a divalent metal ion and M2 is a trivalent metal ion. M1 and M2 are metallic ions of the same or different metal. The suitable metal ions exhibit two stable states of oxidation in an aqueous system. The polymers of this invention are positively charged and are highly hydrophilic. The polymers of this invention are especially useful for changing surface characteristics of a substrate such as imparting hydrophilic properties to normally hydrophobic materials.

To enable the time required to produce an optical substrate on which one or more layers which influence the propagation of light are to be arranged to be reduced, and preferably to provide this optical substrate with significantly lower surface stresses, the invention describes the use of an application method and an optical substrate produced using this method, in which at least one of the layers comprises halogen atoms or a halogen compound as a result of the production.
摘要:
A process for formation of tin oxide film is described, wherein a glass substrate is heated to a high temperature and then tin oxide film is formed on the surface of said substrate by a thermal decomposition oxidation reaction caused by bringing a tin compound or a mixture of a tin compound and a fluorine-containing compound into contact with the surface of said glass substrate, and wherein prior to the formation of tin oxide film, said glass substrate is preliminarily brought into contact with a solution of chloride of a metal belonging to Group IVB of the Periodic Table so that a layer of a composition containing the chloride of the Group IVB metal as the primary component is formed on the surface of said substrate.
摘要:
This invention relates to a method of making glass. In certain example embodiments, a major surface(s) of the glass is treated with aluminum chloride (e.g., AlCl3). This treating, or application of an aluminum chloride based layer on the glass substrate, may be performed using combustion deposition. The combustion deposition may be performed at or just prior to the annealing lehr in certain example embodiments, or at any other suitable location. The aluminum chloride barrier layer, applied at a desirable glass temperature, helps to reduce sodium leaching or diffusion from the glass during conditions such as high heat and/or humidity, thereby improving the durability and/or stability of the resulting product.

摘要:
The invention relates to a method for production of a coated substrate, whereby at least one functional layer is deposited on the substrate from the vapor phase by means of chemical or physical deposition of a coating material and a temporary protective layer is applied to the functional layer by means of evaporation of a salt, in particular, an alkali metal halide. The invention further relates to a coated substrate with at least one functional layer and a temporary protective layer applied to the functional layer, which comprises a salt, in particular, an alkali metal halide, preferably a salt-like alkali metal halide and more particularly sodium chloride.
摘要:
A low-index silica coating may be made by forming silica sol including a silane and/or a colloidal silica. The silica precursor may be deposited on a substrate (e.g., glass substrate) to form a coating layer. The coating layer may then be cured and/or fired using temperature(s) of from about 550 to 700° C. A barrier undercoating including a metal oxide, such as, silica, alumina, titania, zirconia, and/or an oxynitride of silica may be deposited between the coating layer and substrate. Preferably, the barrier undercoating does not substantially affect the percent transmission or reflection of the low-index silica coating. The low-index silica based coating may be used as an antireflective (AR) film on a front glass substrate of a photovoltaic device (e.g., solar cell) or any other suitable application in certain example instances.
摘要:
POSITIVELY CHARGED COATINGS ARE PROVIDED COMPRISED OF POSITIVELY CHARGED PARTICLS OF A SALT OF A METAL, THE METALLIC ELEMENT OF WHICH EXHIBITS TWO STABLE STATES OF OXIDATION SIMULTANEOUSLY WHILE IN SOLUTION. THE COATINGS MAY FURTHER HAVE AN ADDITIONAL LAYER OF NEGATIVELY CHARGED SILICA PARTICLES OVER THE POSTIVELY CHARGED COATINGS. THE COATINGS OF THIS INVENTION ARE SUBSTANTIVE TO NEGATIVELY CHARGED SURFACES SUCH AS GLASS AND ARE ALSO HYDROPHILIC. WHEN WATER STRIKES THE COATED SURFACE, THERE IS A PREFERENTIAL WETTING OUT AND REMOVAL OF SOILS FROM THE SURFACE. THE COATINS OF THIS COMPOSITIONS ARE ESPECIALLY USEFUL AS SOIL RETARDANT COATINS FOR WINDOW GLASS AND OTHER NEGATIVELY CHARGED SURFACES SUDH AS TEXTILES, METALS, PAINTED SURFACES, PLASTIC AND THE LIKE.
