A protective garment is constructed with a fibrous material. The fibrous material comprises a first nonwoven layer, a second nonwoven layer, and a nanofiber layer laminated between the first nonwoven layer and the second nonwoven layer. The fibrous material has a mean flow pore size greater than or equal to about 0.02 micron and less than or equal to about 0.5 microns, and a water vapor transmission rate greater than or equal to about 10000 g/m.sup.2/day and less than or equal to about 100000 g/m.sup.2/day. In a method of making a fibrous layer, a first nonwoven layer and a nanofiber layer are provided. A polyurethane reactive resin is applied to the first nonwoven layer in an amount of 2 to 30 g/m.sup.2. The nanofiber layer is then laminated to the first nonwoven layer applied with the polyurethane reactive resin and pressed to form the fibrous layer.

Methods for forming a fluoropolymer coated component, such as a metal component, comprise applying an adhesion promoter onto a surface of the component; applying an organic material onto the adhesion promoter; and applying a mixture comprising a fluoropolymer and a solvent selected from a furan or a fluorinated solvent onto the organic material. Fluoropolymer coatings have a thickness of from about 5 mil to about 80 mil on a component, an average porosity of from about 20% to about 70% based on the total volume of the layer, and a void density of from about 10.sup.11 to about 10.sup.13 voids per cm.sup.3.

A decorative panel including a substrate material and a decorative top layer, wherein the decorative top layer includes at least one timber layer with a wood structure, wherein the timber layer is a compressed timber layer with naturally occurring vessels throughout a thickness of the wood structure, the vessels being collapsed.

The present invention discloses a polyimide-based composite carbon film with high thermal conductivity and a preparation method therefor. The preparation method includes: uniformly coating the surface of a polyimide-based carbon film with an aqueous graphene oxide solution, and then covering the same with another polyimide-based carbon film uniformly coated with an aqueous graphene oxide solution; repeating such operation; after the polyimide-based carbon films are dried, bonding the polyimide-based carbon films by means of graphene oxide so as to form a thick film; bonding the polyimide-based carbon films more tightly by means of further low-temperature hot pressing; and finally, obtaining a thick polyimide-based carbon film with high thermal conductivity by repairing defects by means of low-temperature heating pre-reduction and high-temperature and high-pressure thermal treatment. The thick polyimide-based carbon film with high thermal conductivity has a thickness greater than 100 μm and an in-plane thermal conductivity of even reaching 1700 W/mK or above.

Due to the increased glazed area of modern vehicles, especially the large panoramic glass roofs, we have seen a substantial growth in the use of anti-reflective coatings. Unfortunately, these types of coatings accentuate fingerprints and smudges. The invention provides an automotive glazing which is substantially resistant to fingerprints, and a method of manufacture thereof through the application of an anti-fingerprint coating based on low surface energy silanes.

A method for making a layered structure without any defects, including a first support layer, a second support layer, and an adhesive intermediate layer interposed between the first layer and the second layer which is adapted to fix the layers on each other. The intermediate layer embeds operatively at least a three-dimensional macroscopic element being made of crystal glass or precious stones, and the intermediate layer is made of a thermoplastic resin having a melting temperature.

Improved wood strand panels suitable for construction are produced by first thermally modifying a plurality of wood strands that are thin in terms of thickness. Then, wood veneers are constructed from the thermally modified wood strands, at least some of which partially overlap one another. The wood veneers are on the order of 0.125 to 0.25 inches thick. Finally, the wood veneers, constructed from the thermally modified wood strands, are stacked on top of one another and connected using adhesive, pressure and temperature similar to plywood or LVL manufacture. The thermal modification and use of thin strands, followed by veneer formation, prior to manufacture of the composite results in a composite with uniform density, high-strength, resistance to decay, resistance to water sorption, and other benefits.

A copper/ceramic bonded body includes: a copper member (12) made of copper or a copper alloy; and a ceramic member (11) made of nitrogen-containing ceramics, the copper member (12) and the ceramic member (11) being bonded to each other, in which a Mg solid solution layer in which Mg is solid-soluted in a Cu matrix is formed at a bonding interface between the copper member (12) and the ceramic member (11), an active metal nitride layer (41) containing a nitride of one or more active metals selected from Ti, Zr, Nb, and Hf is formed on a ceramic member (11) side, and a thickness of the active metal nitride layer (41) is set to be in a range of 0.05 μm or more and 1.2 μm or less.

According to at least one embodiment of the present disclosure, a multilayer elastic film comprises a core layer, a first outer layer, and a second outer layer. The core layer comprises at least 75 wt % polyolefin elastomer such as an ethylene/alpha-olefin block copolymer or a propylene-based plastomer. The first outer layer and the second outer layer each comprise at least 75 wt % of an ethylene-based copolymer, wherein the ethylene-based copolymer is selected from the group consisting of: (I) greater than 50 wt % of ethylene, from 5 to 16 wt % of an α,β-ethylenically unsaturated C3-C8 carboxylic acid, and optionally, from 0.5 to 10 wt % of an alkyl acrylate; (II) from 86 to 95 wt % of ethylene, and from 5 to 14 wt % of an alkyl acrylate; and (III) combinations thereof.
