Patent number: 9090998Abstract: The present invention relates to a dynamic fiber capable of changing in response to external stimuli. The fiber in accordance with the present invention undergoes a radial symmetric change. The fiber in accordance with the present invention may be heat sensitive, moisture sensitive, magnetic field sensitive, electromagnetic field sensitive, etc. Fibers in accordance with the present invention may be incorporated into yarns that may be knitted or woven into textiles/fabrics. Garments or other articles of manufacture may be formed from textiles/fabrics incorporating dynamic fibers, permitting the properties of garments to alter in response to environmental conditions.Type: GrantFiled: June 22, 2012Date of Patent: July 28, 2015Assignee: NIKE, Inc.Inventor: Patrick Williams

Patent number: 9023742Abstract: Provided is a photocatalytic coating in which the coating per se is hardly eroded even when a photocatalyst is excited and a coating surface having strong hydrophobic tendency can be formed. The photocatalytic coating is prepared by dispersing or dissolving at least a photocatalyst, a tetrafluoro-ethylene-based resin obtained by graft polymerization of a sulfonic acid, a compound containing metal ion having an ionic radius not less than an ionic radius of calcium and/or complex ion having an ionic radius not less than the ionic radius of calcium into a solvent. Further, hydroxide is used as the compound containing the metal ion or an electrically neutral surfactant is added to the photocatalytic coating.Type: GrantFiled: February 3, 2011Date of Patent: May 5, 2015Assignees: Metaltech Co., Ltd., Kyushu Institute of TechnologyInventors: Nobuo Saitou, Tohru Kitamura, Teruki Matsukawa, Teruhisa Ohno

Patent number: 8722187Abstract: The disclosure relates to a process that includes blending a polyimide resin and a primary alky amine organic compound to produce an aryl amine functionalized polyimide, having aryl amine functionality in excess of any anhydride functionality. The polyimide resin can have a weight average molecular weight (Mw) from 5,000 to 100,000 daltons. The organic compound can include at least one primary aliphatic amine without a direct linkage of a nitrogen to an aryl group and without a functionality selected from a halogen functionality, a hydroxyl functionality, a sulfonic acid functionality, a sulfonic acid salt functionality, and combinations thereof. The disclosure also relates to alkyl imide functionalized polyimides also with aryl amine functionalized polyimides, having aryl amine functionality in excess of any anhydride functionality and articles produced therefrom.Type: GrantFiled: October 31, 2011Date of Patent: May 13, 2014Assignee: Sabic Innovative Plastics IP B.V.Inventors: Robert R. Gallucci, Roy Odle, Daniel F. Lowery, Richard Peters

Patent number: 8618221Abstract: Methods of directed self-assembly of multi-block (i.e., triblock and higher-order) copolymers on patterned substrates and related compositions are provided. According to various embodiments, the methods involve depositing copolymer materials on substrates configured to drive the assembly of micro-phase separated films that exhibit the same morphology as that copolymer materials in the bulk. In certain embodiments, binary patterns are used to drive the triblock copolymer films. The binary two-dimensional surface patterns are transformed into three-component and three-dimensional structures throughout the thickness of the overlying copolymer films.Type: GrantFiled: October 12, 2006Date of Patent: December 31, 2013Assignee: Wisconsin Alumni Research FoundationInventors: Paul Franklin Nealey, Frank S. Bates, Juan J. de Pablo
