The present subject matter relates to self-healing keyboards. In an example implementation, a self-healing keyboard of an electronic device comprises a self-healing film having a self-healing layer disposed over a keyboard. The self-healing layer is composed of polyurethane, epoxy vinyl ester, epoxy, polyurethane microcapsules filled with silane compound, and a polysiloxane mixture.

The present disclosure provides, among other things, articles with a design material directly applied to a base material to form products with desirable properties.

Combinations of gelatinous elastomer and polyurethane foam may be made by introducing a plasticized A-B-A triblock copolymer resin and/or an A-B diblock copolymer resin into a mixture of polyurethane foam forming components including a polyol and an isocyanate. The plasticized copolymer resin is polymerized to form the gelatinous elastomer in-situ while simultaneously polymerizing the polyol and the isocyanate to form polyurethane foam. The polyurethane reaction is exothermmic and can generate sufficient temperature to melt the styrene-portion of the A-B-A triblock copolymer resin thereby extending the crosslinking and in some cases integrating the A-B-A triblock copolymer within the polyurethane polymer matrix. The combination has a marbled appearance. The gel component has higher heat capacity than polyurethane foam and thus has good thermal conductivity and acts as a heat sink. Another advantage of in situ gel-foam is that the gel component provides higher support factors compared to the base foam alone.

Provided is a developing roller including a shaft body, an elastic layer formed on an external circumference of the shaft body, and a surface layer formed on an external circumference of the elastic layer. The surface layer is formed of polyurethane containing a reaction product of a fluoroethylene vinyl ether copolymer and an isocyanurate form of isocyanate and having a film thickness of from 0.5 μm through 2.0 μm. The developing roller has grooves in a surface of the developing roller. The angle of the grooves from a circumferential direction is from 0 degrees through 30 degrees.

A melamine/formaldehyde foam having an open-cell foam structure, with an impregnation applied to the foam structure that comprises at least one particulate phyllosilicate surface-modified with aminosilane and at least one anionically- and/or nonionically-stabilized polyurethane dispersion.

In an example, a process includes chemically reacting a polyhydroxyalkanoate (PHA) material having a carboxylic-acid terminated side-chain with an azide material to form a polyisocyanate material.

Provided is a wiper blade rubber which has excellent wiping properties and low friction properties with respect to both clean glass surfaces and glass surfaces that have been subjected to a water repellent treatment, and which maintains these properties for a long period of time. A wiper blade rubber which has a lip part wherein a coating layer is provided on a rubber substrate by (a) applying a first coating agent onto a part of the surface of the rubber substrate, (b) curing a first coating layer by heating the rubber substrate onto which the first coating agent is applied, (c) applying a second coating agent onto the surface of the rubber substrate which has the cured first coating layer and (d) drying the second coating agent. The present invention enables the achievement of a wiper blade rubber wherein: the coating layer contains the first coating layer and the second coating layer; and the first coating layer is affixed to a part of the rubber substrate and the second coating layer is affixed to another part of the rubber substrate in the lip part.

Textiles backed with a polyurethane cushion are produced by applying a layer of frothed polyurethane-forming mixture to a surface of the textile. The mixture contains both water and a physical blowing agent. The layer expands due to the action of the water and the physical blowing agent and cures to form an attached cushion having a density of 176 g/L or less.

The invention features a packaging material including a film having a barrier layer formed from an admixture containing a base polymer and a surface-modifying macromolecule. The invention also features containers made from the packaging materials and methods of storing a good.

A synthetic polymer film includes a surface which has a plurality of raised portions. A two-dimensional size of the plurality of raised portions is in a range of more than 20 nm and less than 500 nm when viewed in a normal direction of the synthetic polymer film. The surface has a microbicidal effect. Further, a concentration of a nitrogen element included in the surface is not less than 0.7 at %.
