    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: A condensation management system includes an elongated flexible film configured to be stretched under tension between a first film support and a second film support. The film includes first and second ends that extend laterally across a width of the film. The film includes first and second sides that extend longitudinally between the first and second film ends. The film has a concave surface and an opposing convex surface extending between the first and second sides of the film. Microchannels are disposed in at least one of the concave surface and the convex surface. The microchannels induce a predetermined radius of curvature in the concave and convex surfaces of the film when the film is stretched longitudinally between the first and second film supports.

    Abstract: The present disclosure provides articles having conformal layers and methods of making such articles. An article includes a first polymeric layer having a substantially planar major surface and an opposing major surface bonded to a second polymeric layer. One major surface of the second polymeric layer is conformal to the first polymeric layer while the opposing major surface defines a cavity having at least one wall. The second polymeric layer also has a channel connecting the cavity to at least one edge of the second polymeric layer or to the planar surface of the first polymeric layer. A surface of the cavity exhibits an advancing contact angle with water of less than 90 degrees. A method includes obtaining a tool having protruding features; disposing a first polymer on the protruding features; disposing a second polymer on the first polymer; and applying compression to the polymeric tooling, the first polymer, and the second polymer at an elevated temperature to form the article. The articles can be formed to have small cavities for use as precision fluidic devices, such as blood glucose testing strips.

    Abstract: A fluid control film is provided that includes fluid control channels extending along a channel longitudinal axis. Each of the fluid control channels has a surface and is configured to allow capillary movement of liquid in the channels. The fluid control film further includes a hydrophilic surface treatment covalently bonded to at least a portion of the surface of the fluid control channels. The fluid control film exhibits a capillary rise percent recovery of at least ten percent. Typically, the hydrophilic surface treatment includes functional groups selected from a non-zwitterionic sulfonate, a non-zwitterionic carboxylate, a zwitterionic sulfonate, a zwitterionic carboxylate, a zwitterionic phosphate, a zwitterionic phosphonic acid, and/or a zwitterionic phosphonate. A process for forming a fluid control film is also provided. Further, a process for cleaning a structured surface is provided, including providing a structured surface and a hydrophilic surface treatment covalently bonded to at least a portion of the structured surface, and soiling the structured surface with a material. The process also includes removing the material by at least one of submerging the structured surface in an aqueous fluid, rinsing the structured surface with an aqueous fluid, condensing an aqueous fluid on the structure surface, or wiping the structured surface with a cleaning implement.
