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.

Abstract: Film articles with dual-sided structures are ones in which both of the major surfaces of the film have a structured surface. The structured film articles have a first major surface and second major surface, where each surface has a plurality of spaced apart protrusions forming a repeating pattern. Each repeating pattern has a major axis, where the major axis is one of the major axes in the translational direction of the repeating pattern. The major axis of the repeating pattern on the second major surface forms an oblique angle with the major axis on the first major surface, where the angle is in the range of 10-90% of the angle of rotational symmetry of the repeating pattern. The structured film is a unitary substrate. The structured film articles are prepared by providing a flowable material composition having two major surfaces and simultaneously contacting the major surfaces with a first microstructuring tool, and a second microstructuring tool. Each microstructuring tool has a structured surface including a pattern of a plurality of depressions.

Abstract: A condensation management apparatus comprises a first microstructured film arranged to condense water vapor on a substantially vertical surface of a component. The first film comprises channels disposed on first and second major surfaces of the first film and dimensioned to support capillary movement of condensate. The channels have a channel axis substantially parallel with a longitudinal axis of the first film. The longitudinal axis of the first film is tilted at a tilt angle of at least 4 degrees with respect to an axis normal to a direction of gravity. Openings in the channels are disposed at one or both end edges of the first film. The openings provide condensate release locations of the first film. A second film is disposed over a portion of the first film. The second film attaches the first film to the substantially vertical surface of the component.

Abstract: Three-dimensional polymeric article (100) having first (101) and second (102) opposed major surfaces, a first dimension perpendicular to a second dimension, a thickness orthogonal to the first and second dimensions, and a plurality of alternating first (107) and second (109) polymeric regions along the first or second dimensions, wherein the first (107) and second (108) regions extend at least partially across the second dimension, wherein the first regions (107) are in a common plane (115) and wherein some of the second regions (108) project outwardly from the plane (115) in a first direction (generally perpendicular from the plane), and some of the second regions (108) project outwardly from the plane (115) in a second direction that is generally 180 degrees from the first direction, where the first regions (107) have a first crosslink density, wherein the second regions (108) have a second crosslink density, and wherein the second crosslink density of the second regions (108) are less than the first crosslink density of the first regions (107). Embodiments of the articles are useful for example, for providing a dual-sided, textured wrapping film such that greater grip is realized both on an item wrapped by the film and the wrapped item itself.

Abstract: Light control films are provided that confine light transmitted therethrough to be within a 360° view region and block light outside of this view region. The light control films can provide security in all directions including right-and-left and up-and-down of the films, without compromising light transmittance compared to one-dimensional light control films. The light control films include an array of light transmissive, tapered posts and absorptive regions disposed between the posts.

Abstract: Method for detecting an analyte of interest in a sample. The method can include providing a container comprising a microstructured surface, and centrifuging the container toward the microstructured surface to form a sediment and a supernatant of the sample. Following centrifugation, the container can be inverted to decant at least a portion of the supernatant of the sample from the second portion, such that a concentrate (e.g., comprising the sediment) of the sample is retained in the microstructured surface. The concentrate can then be interrogated in the microstructured surface for the analyte of interest. In some embodiments, at least a portion of the second portion can be substantially transparent, such that the concentrate can be interrogated from the outside of the container, without requiring that the container be opened prior to interrogation.
