Abstract: An article (e.g. film, tape or pipe) is described comprising a microstructured surface. The microstructured surface comprises a thermoplastic polymer; and a block copolymer additive comprising a poly(alkylene)oxide block having a molecular weight greater than 250 or 500 g/mole and at least one hydrophobic block. Also described is a method of making such articles. Also described is a triblock copolymer comprising a poly(alkylene oxide) midblock and hydrocarbon end blocks; and compositions comprising a thermoplastic polymer and un to 50 wt. % of the block copolymer.

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 condensation management apparatus comprises a microstructured film arranged to condense water vapor on an underside of a substantially horizontal surface. The film comprises channels disposed at least on a first major surface and configured to support capillary movement of condensate. The channels have a channel axis substantially parallel with a longitudinal axis of the film. A capillary siphon structure of the film comprises a fold in the film, a condensate collection region proximate the fold, and a siphon region between the fold and a condensate release location of the film. At least a portion of a second major surface is attached to the underside of the substantially horizontal surface such that longitudinal openings of the channels of the condensate collection region are oriented towards a direction of gravity and the condensate release location is positioned lower along the direction of gravity than the condensate collection region.

Abstract: A biological sterilization indicator device is provided. The device comprises a body, a plurality of test microorganisms, and an oxygen-modulated first fluorescent sensor. The body comprises a first layer attached to a second layer, forming at least one isolatable microchamber and at least one primary passageway that provides fluidic communication between ambience and the at least one microchamber. The microchamber has an isolated volume of about 0.5 microliters to about 9.5 microliters. The plurality of test microorganisms and the oxygen-modulated first fluorescent sensor are disposed in the microchamber. A method of using the device to determine the effectiveness of a sterilization process is also provided.

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.
