Abstract:
A transparent conductive article includes a transparent substrate, a thin electrically conductive grid, and a carbon nanolayer. The grid is disposed on the substrate, and the carbon nanolayer is also disposed on the substrate and in contact with the grid. The conductive grid and the carbon nanolayer may have thicknesses of no more than 1 micron and 50 nanometers, respectively. The carbon nanolayer has a morphology that includes graphite platelets embedded in nano-crystalline carbon, and can be produced with a buffing procedure using dry carbon particles without substantially damaging the grid structure. The article may have a visible light transmission of at least 80%, and a sheet resistance less than 500 or 100 ohms/square. The transparent substrate may comprise a flexible polymer film. The disclosed articles may substantially maintain an initial sheet resistance value when subjected to flexing.
Abstract:
An article including an airfoil or hydrofoil is disclosed. On at least a portion of a surface of the airfoil or hydrofoil there is a seamless film having a series of substantially parallel peaks separated from each other by a series of substantially parallel valleys on a patterned first surface of the film, wherein the seamless film has a long dimension that is at least two meters long substantially aligned with the span of the airfoil or hydrofoil, and wherein an angle between the parallel peaks and valleys to the long dimension of the seamless film is at least five degrees. Methods of making the article are also disclosed.
Abstract:
A structured paper release liner (10) for use with an article (44) backed with a pressure sensitive adhesive, an adhesive-backed article assembly (42) and methods of making each are disclosed. The liner (10) comprises a piece of paper (14) having a release side free of a structural support layer, a back side, and a structured release surface (48) having a pattern formed into the paper (14) on the release side. A release material is on the structured release surface of the paper. The pattern formed in the paper (14) is designed so as to form fluid egress channels in a bonding surface of the pressure sensitive adhesive (46). The fluid egress channels define a structured bonding surface (48) having exit pathways for fluid to bleed out from behind the article when the structured bonding surface (48) is adhered to or otherwise disposed on a substrate.
Abstract:
A patterned film is disclosed. The patterned film includes at least a first patterned region and a non-patterned region juxtaposed with the first patterned region on a first surface of the patterned film. The patterned region has a series of substantially parallel peaks separated from each other by a series of substantially parallel valleys. The first patterned region and the non-patterned region extend side-by-side for the length of the patterned film in the machine direction, and the parallel peaks and parallel valleys in the first patterned region extend at an angle of at least five degrees to the machine direction. An article including an airfoil or hydrofoil have a seamless portion of the patterned film on its surface is also disclosed.
