Patent number: 9908274Abstract: This invention is directed to a microstructured filament that can be used to make fibers having an extruded filament having pre-cooled microfeatures in a radial spiral arrangement about a bore though the filament wherein the microfeature has a width in the range of 25 ?m to 40 ?m and height in the range of 90 ?m to 100 ?m; and, the filament having a post-cooled state having post-cooled microfeatures having physical dimensions smaller than that of the pre-cooled microfeatures. The filament can include microfeatures having a width in the range of 400 nm to 4 ?m and height in the range of 400 nm to 4 ?m. The filament and fiber can include physical characteristics selected from the group consisting of: hydrophobicity, self-cleaning, increased hydro-dynamic drag coefficients, decreased or increased aerodynamic drag coefficients, increased friction, reduced friction, optical effects, increased adhesion, decreased adhesion, oleophobicity, tactile effects, anti-blocking and any combination of these.Type: GrantFiled: July 28, 2015Date of Patent: March 6, 2018Assignee: Hoowaki, LLCInventors: Ralph A.

Publication number: 20170144202Abstract: Described herein are flexible superhydrophobic films. Also described are methods for imparting superhydrophobicity to a variety of objects, for example objects having any shape or surface contours. For specific applications, the flexible superhydrophobic films include an adhesive backing layer, useful for attaching the film to objects. Some of the films described herein allow for selective control over the wettability of a surface by flexing the film, for example flexing the film results in a more wettable film, a less wettable film or a film having unchanged wettability. Flexible superhydrophobic films described herein also include films which maintain their superhydrophobicity when deformed into a concave or convex curvature.Type: ApplicationFiled: November 2, 2016Publication date: May 25, 2017Inventors: William P. KING, Andrew H. CANNON
