摘要:
A method for increasing a detection distance of a surface of an object illuminated by near-IR electromagnetic radiation, including: (a) directing near-IR electromagnetic radiation from a near-IR electromagnetic radiation source towards an object at least partially coated with a near-IR reflective coating that increases a near-IR electromagnetic radiation detection distance by at least 15% as measured at a wavelength in a near-IR range as compared to the same object coated with a color matched coating which absorbs more of the same near-IR radiation, where the color matched coating has a ΔE color matched value of 1.5 or less when compared to the near-IR reflective coating; and (b) detecting reflected near-IR electromagnetic radiation reflected from the near-IR reflective coating. A system for detecting proximity of vehicles is also disclosed.
摘要:
A material and method are disclosed such that the material can be used to form functional metal pieces by producing an easily sintered layered body of dried metal paste. On a microstructural level, when dried, the metal paste creates a matrix of porous metal scaffold particles with infiltrant metal particles, which are positioned interstitially in the porous scaffold's interstitial voids. For this material to realize mechanical and processing benefits, the infiltrant particles are chosen such that they pack in the porous scaffold piece in a manner which does not significantly degrade the packing of the scaffold particles and so that they can also infiltrate the porous scaffold on heating. The method of using this paste provides a technique deposition/removal process.
摘要:
An apparatus for coating a donor surface that is movable relative to the apparatus with a layer of thermoplastic particles, the particles adhering more strongly to the surface than to one another. The apparatus comprises an application device to apply to the donor surface a fluid stream within which the particles are suspended, a housing surrounds the application device forming an interior plenum for confining the fluid stream, the housing prevents egress of particles from a sealing gap defined between the rim of the housing and the surface to be coated, and a suction source connected to the housing to extract from the plenum excess fluid and particles. In operation, the suction source extracts substantially all particles that are not in direct contact with the donor surface, leaving substantially a single particle layer adhering to the donor surface upon exiting the apparatus.

A method of forming a nano-coating on a substrate comprises: depositing a first layer on a surface of the substrate, the first layer comprising a polymeric composition; depositing a second layer on the surface of the first layer opposite the substrate, the second layer comprising nanographene derivatized with a functional group selected from the group consisting of carboxy, epoxy, ether, ketone, amine, hydroxyl, alkoxy, alkyl, lactones, aryl, functionalized polymeric, functionalized oligomeric groups, and combinations thereof; and repeating the foregoing steps such that multiple alternating layers are formed, wherein each successive occurrence of the first layer is deposited on a previously deposited occurrence of the second layer.
摘要:
A composite includes a substrate, a binder layer disposed on a surface of the substrate; and a nanofiller layer comprising nanographene and disposed on a surface of the binder layer opposite the substrate. In addition, a nano-coating layer for coating a substrate includes multiple alternating layers of the binder layer and the nanofiller layer. Articles coated with the nano-coating layer prepared from alternating layers of nanofiller layer and binder layer have improved barrier properties, and may be used in down-hole applications.
摘要:
Disclosed is a method of forming a composite micropowder, including mixing 100 parts by weight of fluorine-containing polymer, 10 to 140 parts by weight of silane, catalyst, and water, such that the silane is in-situ polymerized in the fluorine-containing polymer to form a polysiloxane, and the fluorine-containing polymer and the polysiloxane form a composite. The composite is dried, and then physically crushed to form composite micropowder. The total weight of the fluorine-containing polymer and the silane and the weight of the catalyst have a ratio of 100:1 to 100:0.0001. The silane and the water have a molar ratio of 1:0.5 to 1:3. The composite micropowder has a diameter of 0.1 μm to 15 μm. The fluorine-containing polymer and the polysiloxane in the composite micropowder have a weight ratio of 95:5 to 60:40.
摘要:
A colored system including a coated substrate and a color pigment that adheres to the coated substrate, and a method for producing the colored system are described. The disclosed method adheres effectively the color pigments to the coated substrates. The resulting colored system avoids their separation during coating applications. The colored metallic paints/inks can be prepared by mixing a color pigment solution with a coated substrate solution. The resulting colored system displays vivid color and strong metallic luster.
摘要:
A process for preparing embossed fine particulate thin metal flakes having high levels of brightness and color intensity. The process comprises forming a release coat on a flexible polymeric carrier film, embossing the release coat with a diffraction grating pattern that is monoruled at an angle above 45°, vacuum metalizing the embossed release surface with a highly reflective metal such as aluminum, and solubilizing the metalized release coat in a solvent for removing the metal from the carrier to form embossed metal flakes that replicate the embossment pattern. The flakes are recovered from the solution containing the solvent and release coat polymer while avoiding high shear, particle sizing or other application of energy that would excessively break up the flakes, so that the D50 particle size of the flakes is maintained at or above 75 microns. The flakes have application to coatings and printing inks that produce extremely high brightness characterized as an optically apparent glitter or sparkle effect in combination with high color intensity or chromaticity.
