An article includes an optical filter that comprises a wavelength selective reflective layer and at least one wavelength selective absorbing layer. The optical filter has visible transmittance between 400 nm-700 nm of less than about 30% and near infrared transmittance at 830 nm-900 nm greater than about 30%.

Optical camouflage filters

Apparatus and method useful for, among other things, providing a layer by layer coating of materials on a substrate.

Layer-by-layer coating apparatus and method

Apparatus and method are described and useful for, among other things, providing a layer by layer coating of materials on a belt. A directional gas curtain producing element is used to provide a gas curtain blowing on the belt in an upstream direction that simultaneously meters liquid from the belt and dries the belt.

A barrier film. The barrier film may include a substrate, an inorganic layer disposed on a side of the substrate, and an organic layer-by-layer structure disposed on a side of the inorganic layer, where in the organic layer-by-layer structure comprises a layer of a cationic polyelectrolyte and a layer of an anionic polyelectrolyte.

Multilayer barrier films

Electrically conductive patterns formed on a substrate are provided with a reduced visibility. A region of a major surface of the substrate is selectively roughened to form a roughened pattern on the major surface of the substrate. Electrically conductive traces are directly formed on the roughened region and are conformal with the roughened pattern on the major surface of the substrate.
