摘要： 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.

摘要： 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. Articles and methods are also described.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： A patterned conductive article 200 includes a substrate 210 including a unitary layer 210-1 and includes a micropattern of conductive traces 220 embedded 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 layer 230 having a top major surface 232 and an opposite bottom major surface 234 in direct contact with the unitary layer; and a unitary conductive body 240 disposed 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 sidewalls 242, 244 and at least a majority of a total area of the lateral sidewalls is in direct contact with the unitary layer.

摘要： 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.-

摘要： 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%.
