摘要:
A deployable structure includes a hydride material to be converted into hydrogen gas; and a sheet material encapsulating the hydride material; wherein the sheet material is to be plastically deformed by the hydrogen gas to have an expanded structure. A method of manufacturing a deployable structure includes: forming a sheet material comprising an outer shell structure and a hollow interior; placing a hydride material capable of being converted into hydrogen gas into the hollow interior; sealing the outer shell structure; and converting and releasing the hydrogen gas to expand and plastically deform the sheet material.

A laminate film including a first polylactic acid layer; a second metal-receiving layer including PVOH, EVOH, or a blend thereof on a side of the first polylactic acid layer; and a metal layer deposited on a side of the metal-receiving layer opposite the polylactic acid layer. The metal-receiving layer may be coextruded with the polylactic acid first layer or may be a coating applied to one side of the polylactic acid first layer. This laminate film exhibits excellent gas and moisture barrier properties, appearance, and metal adhesion. It may also include a heat sealable or winding improving layer on the side opposite the metal receiving-layer of the first polylactic acid layer.

A gas barrier film is provided comprising a base film of polyester provided, on at least one of its surfaces, with a deposited layer of an inorganic compound and a gas barrier layer of a copolymer resin composition formed on the former. The gas barrier layer is produced from a mixture of a base material composed at least of the two components of (a) an unsaturated nitrile that accounts for 10% to 30% by mass of the copolymer and (b) an unsaturated compound with a hydroxyl group that accounts for 30% to 70% by mass of the copolymer; (c) a curing agent that contains a compound with an isocyanate group; and (d) a compound that has either two or more carboxylic acid groups or one or more carboxylic anhydride groups.

A getter device containing a combination of getter materials is described. The device has a mixture of cerium oxide, copper oxide and metallic palladium for the removal of hydrogen and carbon monoxide in vacuum applications, particularly suitable to be used in vacuum insulation applications. This combination of getter materials is preferably added to powders of other getter materials such as alkali metals hydroxides and desiccant materials that are effective for maintaining the vacuum in thermal insulation systems.
摘要:
A laminate film including a first core polylactic acid layer, a coating receiving-layer of polylactic acid, and coated on one side of the coating receiving-layer with PVOH, EVOH, a blend of crosslinked EVOH/PVOH, vinyl alcohol-vinylamine (PVAm) copolymer, anionic carboxylated styrene-butadiene copolymer (SBR) emulsion, or blends thereof. This coating may be applied after the machine-direction orientation step and dried and oriented in a transverse direction orientation oven if in-line coating is desired; or applied to the film in an off-line coating method and dried in an air flotation oven. The dried coating layer can be metallized. This laminate film exhibits excellent gas and moisture barrier properties, appearance, and metal adhesion. It may also optionally include a heat sealable or winding improving layer on the side opposite the coating receiving-layer of the core layer.

摘要:
A gas-barrier laminate comprises a plastic substrate (A), an inorganic thin film (B) formed on at least one surface of the plastic substrate (A), and a polyester-based resin layer (C) formed by applying a coating material containing a polyester-based resin on a surface of the inorganic thin film (B), wherein the polyester-based resin has a glass transition temperature of 50 to 70° C., a molecular weight of 1500 to 15000 and a hydroxyl value of 10 to 60 mg KOH/g, and the gas-barrier laminate has an oxygen permeability of not more than 5 cc/m2/day/atm and a water vapor permeability of not more than 5 g/m2/day. The gas-barrier laminate of the present invention is excellent in printability (in particular, gradation printability), is free from deterioration in gas-barrier property, namely is excellent in gas-barrier property, even after providing a printed layer thereon, and further exhibits an excellent adhesion between the plastic substrate (A) and the inorganic thin film (B) even after being subjected to retort treatments.
