    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 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: Polymeric multilayer film having first and second generally opposed major surfaces, and comprising first, second, and third layers, an array of blind openings between the first and second major surfaces, and an average thickness, wherein the first, second, and third layers each have a first average thickness excluding any thickness said first, second, and third layers having in any of the blind openings, wherein the first and second layers extend into the first average thickness of the third layer, wherein each of the first, second, and third layers each have a second average thickness (including a thickness of zero) in the blind holes, wherein the second average thickness of the first and third layers are each greater than zero, and wherein the ratio of the first average thickness of the second layer to the second average thickness of the second layer is at least 2.1; and method of making the same. Embodiments of polymeric multilayer film described herein are useful, for example, for acoustic absorption.

    Abstract: Coextruded polymeric layer having first and second opposed major surfaces, the coextruded polymeric layer comprising foam and the coextruded polymeric layer comprising features extending from or into the first major surface by at least 100 micrometers, the first major surface comprising a first material having a first percent elongation at break, the second major surface comprising a second material having a second percent elongation at break, wherein the first percent elongation at break is greater than 100 percent of the second percent elongation at break. Coextruded polymeric layers described herein are useful, for example, in vibration damping applications (e.g., a vibration damping laminate comprising a kinetic spacer comprising the coextruded polymeric layers).
