Abstract: A surface covering for use as a moss covering or patch of grass via application to a surface or substrate. The surface covering provides a decorative and durable and easily maintained surface covering. The covering is fabricated using groups of fibers, such as metallic, plastic, or other material fibers, e.g., stainless steel fibers or strands available commercially as steel wool or the like. The fibers or strands provide a core of a body of each blade or piece of the surface covering, which is useful to replicate a blade of grass or moss or to mimic a strand of hair. Each body of the strands further includes an outer layer or coating, which can be formed by painting, e.g., with an epoxy or other useful material that may be colored, the mesh of metal fibers to provide a durable body with a desired look and feel.

Abstract: Described herein is a method for coating an object with a polymer layer. The method includes contacting the object with a first solution comprising a non-polymeric grafting initiator comprising at least one photoinitiator group capable of generating a free radical active species upon absorption of electromagnetic energy, wherein the photoinitiator group is selected from the group consisting of an initiator that is insoluble in polar solvent; and a negatively charged initiator; irradiating the first solution and the object, resulting in the grafting initiator binding to the object; removing the first solution; contacting the object with a second solution comprising a polymerizable monomer having at least one free-radical polymerizable group; and irradiating the second solution and the object, wherein the non-polymeric grafting initiator acts as a photoinitiator for a free-radical polymerization reaction.

Abstract: This invention provides a coating apparatus and methods for coating a device, such as an industrially or medically applicable device.

Abstract: A process and apparatus for dip-coating intermediate and/or discrete discontinuous portions of longitudinal devices, including medical devices such as catheters and guidewires. The apparatus provides a chamber in which both the desired portion(s) of the device and the coating solution can be controllably contacted. A controlled coating can be achieved within the chamber by providing and controlling one or more of the following relationships: a) the manner in which a chamber (containing solution) is itself moved with respect to a static device, b) the manner in which the device is moved with respect to a fixed chamber position containing a fixed volume of solution, and/or c) the manner in which both the chamber and device are fixed in position, and the coating is achieved by adding and removing a volume of solution from the chamber.
