Abstract: A patterned article includes a carrier layer having a microstructured first major surface and an opposing second major surface. The first major surface includes pluralities of upper and lower edges spaced apart along a thickness direction of the carrier layer and defining respective upper and lower portions of the first major surface. The lower portion is disposed between the upper portion and the second major surface. The article includes a first functional layer disposed on the lower, but not the upper portion of the first major surface. The first functional layer includes at least one first micro-cut inorganic layer including a plurality of cut edges substantially coextensive with the plurality of lower edges. A method of making the patterned article is provided. Articles that can be made by transferring a functional layer from the patterned article are provided.

Abstract: Structured surfaces are described. In one embodiment, the structured surface comprises a plurality of structures having a complement cumulative slope magnitude distribution (Fcc) such that at least 30, 40, 50, 60, 70, 80 or 90% of structures have a slope greater than 10 degrees; and less than 80% of the structures have a slope greater than 35 degrees. In other embodiments, the structures comprise peaks and valleys defined by a Cartesian coordinate system such that the peaks and valleys have a width and length in the x-y plane and a height in the z-direction and at least a portion of the peaks and/or valleys vary in height in the y direction and/or the x-direction by at least 10% of the average height.

Abstract: Medical diagnostic devices or components thereof are described that comprise a microstructured surface that comprises peak structures and adjacent valleys wherein the valleys have a maximum width ranging from 1 to 1000 microns and the peak structures. In some embodiments (e.g.
for improved cleanability) the peak structures of the microstructured surface have a side wall angle of 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-comers elements. The microstructured surface of the medical diagnostic device typically comes in contact with multiple patients during normal use of the device, such as a stethoscope diaphragm. The microstructured surface exhibits better microorganism (e.g. bacteria) removal when cleaned and/or provides a reduction in microbial touch transfer. Also described are methods of making and methods of use.-

Abstract: A solar cell is described that comprises a transparent conductor sheet having a polymeric substrate with an embedded metal grid, disposed within microchannels extending partially through a thickness of polymeric substrate from a first surface of the polymeric substrate; and a photoactive layer disposed adjacent to the first surface of the polymeric substrate. The transparent conductor sheet has a sheet resistance less than 1 Ω/□ and an average solar direct transmittance over the visible and infrared portion of the spectrum of at least about 80%.

Abstract: 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.

Abstract: A light control film includes a plurality of substantially parallel optical cavities. Each of the optical cavities has a height H along a thickness direction of the light control film and a minimum lateral dimension W along an in-plane width direction orthogonal to the thickness direction, where H≥W. The optical cavities are substantially filled with a liquid including a plurality of light absorbing particles configured to move along the thickness direction in response to one or more applied signals or fields such that the movement along the thickness direction causes each of the optical cavities to transition between a substantially opaque state and a substantially transparent state. A full viewing angle of the light control film increases when the optical cavities transition from the substantially opaque state to the substantially transparent state.

Abstract: 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.
