Abstract: Superhydrophobic film articles have a microstructured surface. The microstructured surface is free of nanostructures and contains a random arrangement of protrusions that form cavities. The superhydrophobicity is achieved by the selection of the materials of which the microstructures are formed or by a surface coating on the microstructured surface.

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: The present disclosure provides a light control film that is capable of transmitting light, or allowing a viewer to observe information, only within a viewing region centered around the normal (perpendicular line) to a surface. The light control film generally blocks information or light outside of this viewing region, and provides security in all directions including right-and-left and up-and-down of the film. The light control film includes a plurality of light-transmissive cavities that are surrounded by a light absorbing material, such that each of the plurality of cavities is optically isolated from adjacent cavities. Each of the light-transmissive cavities effectively block light which enters the cavity outside of a viewing (that is, cutoff) angle.

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: 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 retroreflective system is disclosed that includes a retroreflective sheet for retroreflecting light, and a light control film disposed on the retroreflective sheet. For a first wavelength, light incident on the light control film at each of a first and second angles of incidence is retroreflected. For a second wavelength, light incident on the light control film at the first, but not the second, angle of incidence is retroreflected.

Abstract: A co-extrusion method for making a replicated film. The method includes the steps of providing at least three materials and co-extruding them between a nip roll and a structured roll. The materials include a backside layer material, a core layer material, and a replicated layer material. The structured roll has a surface structure that is replicated onto the replicated layer, and the core layer is an internally conformable layer that conforms with the replicated layer.
