Films and articles are described comprising a microstructured surface having an array of peak structures and adjacent valleys. For improved cleanability, the valleys preferably have a maximum width ranging from 10 microns to 250 microns and the peak structures have a side wall angle greater than 10 degrees. The peak structures may comprise two or more facets such as in the case of a linear array of prisms or an array of cube-corners elements. The facets form continuous or semi-continuous surfaces in the same direction. The valleys typically lack intersecting walls. Also described are methods of making and methods of use. The microstructured surface of the article can be prepared by various microreplication techniques such as coating, injection molding, embossing, laser etching, extrusion, casting and curing a polymerizable resin; and bonding microstructured film to a surface or article with an adhesive.

Microstructured surface with increased microorganism removal when cleaned, articles and methods

A patterned conductive article includes a substrate having a first groove therein; a conductive seed layer disposed in the first groove; and a unitary conductive body disposed at least partially in the first groove. The conductive seed layer covers at least a majority of a bottom surface of the first groove, and the unitary conductive body covers the conductive seed layer and at least a majority of side surfaces of the first groove. In a plane through the unitary conductive body that is parallel to and separate from the conductive seed layer, the unitary conductive body has a lower first line edge roughness at a first interface with the side surfaces and the conductive seed layer has a higher second line edge roughness at an edge of the conductive seed layer.

Patterned conductive article

An article includes a polishing layer that includes a plurality of raised cells separated by a plurality of channels. Each of the plurality of raised cells includes a microstructured working surface, a substantially vertical channel surface, and an offset surface between an edge of the working surface and an upper edge of the channel surface. The microstructured working surface includes a plurality of microstructures. Tops of the plurality of microstructures define a top plane and bases of the plurality of microstructures define a base plane. The substantially vertical channel surface defines a wall of a channel of the plurality of channels and the channel surface defines a channel plane. The offset surface includes a nonplanar portion of displaced material. The displaced material defines a displacement plane that is below the base plane or within a tolerance of the top plane.

Microreplicated polishing surface with enhanced co-planarity

A patterned article includes a unitary polymeric layer and a plurality of electrically conductive elements embedded at least partially in the unitary polymeric layer. Each electrically conductive element includes a conductive seed layer having a top major surface and an opposite bottom major surface in direct contact with the unitary polymeric layer, and includes a metallic body disposed on the top major surface of the conductive seed layer. The metallic body has a bottom major surface and at least one sidewall. The bottom major surface contacts the conductive seed layer. Each sidewall is in direct contact with the unitary polymeric layer and extends from the bottom major surface of the metallic body toward or to, but not past, a top major surface of the unitary polymeric layer. The conductive elements may be electrically isolated from one another. Processes for making the patterned article are described.

Patterned article including electrically conductive elements

A patterned conductive articleincludes a substrateincluding a unitary layer-and includes a micropattern of conductive tracesembedded at least partially in the unitary layer. Each conductive trace extends along a longitudinal direction (y-direction) of the conductive trace and includes a conductive seed layerhaving a top major surfaceand an opposite bottom major surfacein direct contact with the unitary layer; and a unitary conductive bodydisposed on the top major surface of the conductive seed layer. The unitary conductive body and the conductive seed layer differ in at least one of composition or crystal morphology. The unitary conductive body has lateral sidewallsand at least a majority of a total area of the lateral sidewalls is in direct contact with the unitary layer.

Method and apparatus to provide a weatherproof enclosure for one or more padlocks. The invention incorporates a weatherproof case cover and case body sized and shaped to house a plurality of padlocks together with the two looped ends of a cable that is used to secure a gate or other opening. Two donut shaped gaskets made of a resilient material are positioned on the cable in order that they make secure compressed contact with the case cover and case body when they are in a closed position. The case cover and case body are both shaped to receive the donut shaped gaskets at the points of contact and yet sufficiently compress the gaskets to form a weatherproof seal. The case cover and case body are sized and shaped in order that both have a channel at the point of contact between the case cover and case body. A gasket in two sections is positioned in the channel and is sized and shaped to be slightly compressed when the case cover and case body are in a closed position resulting in a continuation of the weatherproof seal.
