Abstract:
An ultra-clear rub and scratch resistant aqueous based coating that provides barrier properties to film and is receptive to flexo, litho, and gravure printing inks includes polyurethane acrylic hybrid dispersion in combination with melamine formaldehyde resin and micronized wax. The coating composition can be formulated with little or no N-methylpyrrolidone. This coating can be applied to a wide variety of different polymers such as polyesters, metalized polyesters, polyamides, metalized polyamides, biaxially oriented polypropylene, and others.
Abstract:
There is provided an article comprising at least a first surface having: (a) a first binder layer; (b) a plurality of transparent microspheres at least partially embedded in the first binder layer; wherein the transparent microspheres have refractive indices that are less than a refractive index of the first binder layer, wherein the plurality of transparent microspheres have an average diameter of at least 5 µm. There is also provided a transfer article comprising: (a) a transfer carrier, the transfer carrier comprising: (i) a support layer; and (ii) a thermoplastic release layer bonded to the support layer; (b) a layer of a plurality of transparent microspheres, formed on a side of the thermoplastic transparent microsphere release layer opposite the support layer, wherein the plurality of transparent microspheres have refractive indices of below about 1.490.
Abstract:
An article with a liquid-impregnated surface (120), the surface (120) having a matrix of features (124) thereupon, spaced sufficiently close to stably contain a liquid (126) therebetween or therewithin, and preferable also a thin film thereupon. The surface (120) provides the article with advantageous non-wetting properties. Compared to previous non-wetting surfaces (104), which include a gas (110) (e.g., air) entrained within surface textures (108), these liquid-impregnated surfaces (120) are resistant to impalement and frost formation, and are therefore more robust.
Abstract:
A method is provided for making a high repellency material. In one embodiment the method includes the steps of providing a polymeric material having an external surface including particle-like micron-scale topography, etching the external surface with a high energy treatment; and depositing a fluorochemical onto the etched external surface by a plasma fluorination process. The external surface may define a plurality of micro-tears proximate the micron-scale topography.
Abstract:
Systems and method of manufacturing wafers are disclosed using a low EPD crystal growth process and a wafer annealing process are provided resulting in III-V/GaAs wafers that provide higher device yields from the wafer. In one exemplary implementation, there is provided a method of manufacturing a group III based material with a low etch pit density (EPD). Moreover, the method includes forming polycrystalline group III based compounds, and performing vertical gradient freeze crystal growth using the polycrystalline group III based compounds. Other exemplary implementations may include controlling temperature gradients(s) during formation of the group III based crystal to provide very low etch pit density.
