Low dielectric constant films with improved elastic modulus. The method of making such coatings involves providing a porous network coating produced from a resin containing at least 2 Si-H groups and plasma curing the coating to convert the coating into porous silica. Plasma curing of the network coating yields a coating with improved modulus, but with a higher dielectric constant. The costing is plasma cured for between about 15 and about 120 seconds at a temperature less than or about 350° C. The plasma cured coating can optionally be annealed. Rapid thermal processing (RTP) of the plasma cured coating reduces the dielectric constant of the coating while maintaining an improved elastic modulus as compared to the plasma cured porous network coating. The annealing temperature is typically loss than or about 475° C., and the annealing time is typically no more than or about 180 seconds. The annealed, plasma cured coating has a dielectric constant in the range of from about 1.1 to about 2.4 and an improved elastic modulus.

Compositions and methods for manufacturing sheets having a highly inorganically filled matrix. Suitable inorganically filled mixtures are prepared by mixing together an organic polymer binder, water, one or more inorganic aggregate materials, fibers, and optional admixtures in the correct proportions in order to form a sheet which has the desired performance criteria. The inorganically filled mixtures are formed into sheets by first extruding the mixtures and the passing the extruded materials between a set of rollers. The rolled sheets are dried in an accelerated manner to form a substantially hardened sheet, such as by heated rollers and / or a drying chamber. The inorganically filled sheets may have properties substantially similar to sheets presently made from traditional materials like paper, cardboard, polystyrene, plastic, or metal. Such sheets can be rolled, pressed, scored, perforated, folded, and glued. They have especial utility in the mass production of containers, particularly food and beverage containers.

Compositions and methods for manufacturing sheets having a starch-bound matrix reinforced with fibers and optionally including an inorganic mineral filler. Suitable mixtures for forming the sheets are prepared by mixing together water, unmodified and ungelatinized starch granules, an auxiliary water-dispersible organic polymer, fibers, and optionally an inorganic mineral filler in the correct proportions to form a sheet having desired properties. The mixtures are formed into sheets by passing them between one or more sets of heated rollers to form green sheets. The heated rollers cause the auxiliary polymer to form a skin on the outer surfaces of the sheet that prevents the starch granules from causing the sheet to adhere to the rollers upon gelation of the starch. The green sheets are passed between heated rollers to gelatinize the starch granules, and then to dry the sheet by removing a substantial portion of the water by evaporation. The starch and auxiliary polymer form the binding matrix of the sheets with the fibers and optional inorganic filler dispersed throughout the binding matrix. The starch-bound sheets can be cut, rolled, pressed, scored, perforated, folded, and glued to fashion articles from the sheets much like paper or paperboard. The sheets are particularly useful in the mass production of containers, such as food and beverage containers.

A composite multi-layer barrier is produced by first vapor depositing a barrier under vacuum over a substrate of interest and then depositing an additional barrier at atmospheric pressure in a preferably thermoplastic layer. The resulting multi-layer barrier is then used to coat an article of interest in a lamination process wherein the thermoplastic layer is fused onto itself and the surface of the article. The vacuum-deposited barrier may consists of a first leveling polymer layer followed by an inorganic barrier material sputtered over the leveling layer and of an additional polymeric layer flash evaporated, deposited, and cured under vacuum. The thermoplastic polymeric layer is then deposited by extrusion, drawdown or roll coating at atmospheric pressure. The resulting multi-layer barrier may be stacked using the thermoplastic layer as bonding agent. Nano-particles may be included in the thermoplastic layer to improve the barrier properties of the structure. A desiccant material may also be included or added as a separate layer.

In a preferred embodiment, the metal layer is aluminum having a thickness of about 100 nm and the dielectrics are either silicon dioxide or magnesium fluoride, each having a thickness of about 100 nm. The result is a very thin three-layered metal flake about 300 nm thick that exhibits a uniaxial compressive strength of about 8 times a corresponding uniaxial tensile strength. As a result, the metal flake is then afforded the benefits of rigidity and brittle fracture during the manufacturing and applicational processes which ultimately provides favorable planar and specular reflectance characteristics in the visible wavelength range.

A glass laminate substrate for electronic substrates, such as flat panel displays, includes a transparent glass core bounded by transparent glass skin layers, wherein the coefficient of thermal expansion of the core is greater than the coefficient of thermal expansion of the skin layers thereby forming a residual compressive stress in the skin layers and a residual tensile stress in the core. The relative thickness of the skin layers can be selected to enhance the strength of the glass laminate substrate while maintaining a sufficiently low residual tensile stress in the core to allow scribing and separating of the substrate to size. Interlayers can be located between the core and the skin layers, wherein the interlayers include a residual compressive stress, and produce a reduced residual tensile stress in the core.

A method of passivating the interior surface of a gas storage vessel to protect the surface against corrosion. The interior surface of the vessel is first dehydrated and then evacuated. A silicon hydride gas is introduced into the vessel. The vessel and silicon hydride gas contained therein are heated and pressurized to decompose the gase. A layer of silicon is deposited on the interior surface of the vessel. The duration of the silicon depositing step is controlled to prevent the formation of silicon dust in the vessel. The vessel is then purged with an inert gas to remove the silicon hydride gas. The vessel is cycled through the silicon depositing step until the entire interior surface of the vessel is covered with a layer of silicon. The vessel is then evacuated and cooled to room temperature.

A low friction top coat over a multilayer metal / ceramic bondcoat provides a conductive substrate, such as a rotary tool, with wear resistance and corrosion resistance. The top coat further provides low friction and anti-stickiness as well as high compressive stress. The high compressive stress provided by the top coat protects against degradation of the tool due to abrasion and torsional and cyclic fatigue. Substrate temperature is strictly controlled during the coating process to preserve the bulk properties of the substrate and the coating. The described coating process is particularly useful when applied to shape memory alloys.
