A device for coating a fiber includes a fiber receiving arrangement and a coating arrangement which includes an application unit which wets the fiber with a coating agent, and a curing unit arranged downstream of the application unit which optically cures the coating agent. The curing unit includes a lamp which emits at least one light beam which is aimed directly or indirectly at a surface of the fiber. A main radiation direction of the lamp includes a beam angle between the main radiation direction and a longitudinal direction of the fiber of less than 40°. The fiber receiving arrangement and the application unit are movable relative to each other in the longitudinal direction of the fiber via a translational motion arrangement so that a wetting process is implemented substantially along an entire length of the fiber.

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.

The invention relates to a patterned transparent conductive film, comprising areas with higher conductivity and areas with lower conductivity, wherein in the areas with higher conductivity nanoobjects are disposed in a binder matrix such that the nanoobjects are interconnected and thereby form an area with higher conductivity and wherein in the areas with lower conductivity the nanoobjects are structurally intact and are coated with an insulating coating material. The invention further relates to a process for producing such a patterned transparent conductive film comprising areas with lower conductivity and areas with higher conductivity, comprising following steps: (a) applying an ink comprising electrically conductive nanoobjects and a binder on a substrate, forming a first layer, wherein the amount of conductive nanoobjects is such that the first layer is conductive after drying; (b) drying of the first layer; (c) applying a mixture comprising an insulating coating material or a precursor of an insulating coating material on that parts of the first layer which shall form the areas with lower conductivity, wherein the insulating coating material or the precursors form an insulating coating around the electrically conductive nanowires; (d) drying of the coated substrate.

Methods for treating cellulosic materials comprising introducing a liquid treating composition into the cellulosic material, the treating composition comprising a solution prepared from at least: (i) one or more of a copper amine complex or copper ammine complex, such as copper tetraamine carbonate, (ii) one or more of ammonia or a water-soluble amine and (iii) water; and exposing the cellulosic material provided thereby to carbon dioxide and/or carbonic acid to provide treated cellulosic material, and treated cellulosic materials prepared thereby.

Provided is a pore-filling method for protecting the pores of a porous material. The method, which is performed using a modified i-CVD technique, involves filling the pores of a porous material with a gas phase monomer within a pressure chamber and subsequently polymerizing the monomer, both within the pores and on the surface of the material as an overburden. The method is solvent-free and can fill and protect pores of any size of any material.
