摘要： Articles including repellent surfaces and methods of making and using these articles are disclosed. The repellant surface can comprise a polymer having a roughened surface and a fluorinated silane and a lubricating liquid deposited on the roughened surface. The repellent surface, and by extension the articles described herein, can exhibit superomniphobic properties. The methods for producing the repellant surface can comprise dissolving a polymer in a solvent to produce a polymer solution and optionally adding a non-solvent to the polymer solution to produce a casting mixture. The polymer solution or casting mixture can be deposited on a surface of a substrate and the solvent and/or the non-solvent evaporated to provide a coated-substrate having a roughened surface. A functional layer comprising a fluorinated silane followed by a lubricating liquid can be deposited on the roughened surface to form the repellant surface.

摘要： The present invention relates to a method for reducing an amount of glass filaments separating from pellets comprising a thermoplastic polymer sheath intimately surrounding the glass filaments. The method can include transporting the pellets through a piping system and/or by a vibrating conveyor means. The pellets have a length of at least 13 mm. The amount of glass filaments separating from the pellets when such pellets are subjected to repetitive mechanical loads in transportation is reduced as compared other pellets subjected to the same repetitive mechanical load, such that blocking caused by the glass filaments within the pellet transport system is reduced or eliminated as compared to transporting pellets having a length of less than or equal to 12.1 mm.

摘要： It is aimed to provide an insulated wire capable of enhancing the flame retardancy thereof by a method other than a method for increasing a content of a flame retardant in an insulation coating. An insulated wire includes a wire conductor and an insulation coating made of a resin composition for covering an outer periphery of the wire conductor. A cross-sectional area ratio S defined as a ratio S2/S1 of a cross-sectional area S2 of the insulation coating to a conductor cross-sectional area S1 and an oxygen index OI of the resin composition constituting the insulation coating satisfy a relationship of S≤OI−17.2.

摘要： Disclosed is a nonaqueous electrolyte battery using an aqueous sealant composition. The aqueous sealant composition comprises an aqueous dispersion in an amount of 70 mass % or more and 97 mass % or less by mass of solid content, wherein the aqueous dispersion comprises an olefinic polymer as a main component, and a water-soluble polymer in an amount of 3 mass % or more and 30 mass % or less by mass of solid content. The aqueous dispersion comprises an olefinic polymer as a main component. The olefinic polymer is a modified olefinic polymer. The modified olefinic polymer is a partial copolymer of a polymer selected from a group consisting of polyethylene, polypropylene, polybutene and ethylene-propylene polymers, and a polymerizable unsaturated organic acid selected from a group consisting of maleic anhydride, acrylic acid, methacrylic acid and esters thereof.

摘要： A fabrication method for a press hardened part is provided. A sheet or a steel substrate blank for heat treatment is provided. A pre-coating is applied. The pre-coating has at least one layer of aluminum or aluminum alloy in contact with the steel substrate on at least one of the principal faces of the sheet or blank. Then a polymerized layer is deposited on the pre-coating. The polymerized layer has a thickness between 2 and 30 μm. The polymerized layer does not contain silicon, has a nitrogen content of less than 1% by weight and carbon pigments in a quantity between 3 and 30% by weight. The blank or the sheet is heated to obtain an interdiffusion between the steel substrate and the pre-coating and to give the steel a partly or totally austenitic structure. Then the blank or the sheet is hot stamped to obtain a part. The part is cooled by holding the part in a stamping tool so that the microstructure of the steel substrate includes, at least in a portion of the part, martensite or bainite.
