Publication number: 20240101724Abstract: The present invention relates to articles comprising crosslinked polymer network comprising thioether crosslinks and process of making and using same. Such thiol-ene crosslinking reactions not only make the isocyanate crosslinking reaction unnecessary, but they also improve the article's strength due to chemical crosslinking between the article's resin layers, and reduce or eliminate post curing. Thus resulting in a sufficiently cured article in a much shorter time.Type: ApplicationFiled: November 30, 2023Publication date: March 28, 2024Inventors: Levi Michael Joseph Moore, Jacob C. Marcischak, Timothy S. Haddad, Kamran B. Ghiassi, Gregory R. Yandek

Patent number: 8580027Abstract: Fluoroalkylsilane-treated metal oxide particles and a fluoroelastomeric binder are dispersed in a fluorinated solvent with a low boiling point and applied to a substrate via spray deposition. The spray deposition process rapidly produces a conformal coating that features low surface energy and surface topography with a large range of characteristic length scales and re-entrant curvature, thereby imparting superoleophobicity. The degree of superoleophobicity is readily adjusted by means of altering the ratio of particles to binder. The choice of particle and binder result in coatings with thermal stability for thousands of hours at temperatures up to 200 degrees Celsius as well as desirable mechanical characteristics.Type: GrantFiled: August 11, 2011Date of Patent: November 12, 2013Assignee: The United States of America as represented by the Secretary of the Air ForceInventors: Raymond Campos, Andrew J.

Patent number: 7897667Abstract: A method of using fluorinated-nanostructured POSS chemicals as alloying agents for the reinforcement of polymer microstructures, including polymer coils, domains, chains, and segments, at the molecular level. Because of their tailorable compatibility with nonfluorinated polymers, nanostructured chemicals can be readily and selectively incorporated into polymers by direct blending processes. The incorporation of a nanostructured chemical into a polymer favorably impacts a multitude of polymer physical properties. Properties most favorably improved are surface properties, such as lubricity, contact angle, water repellency, deicing, surface tension, and abrasion resistance. Improved surface properties may be useful for applications such as anti-icing surfaces, non-wetting surfaces, low friction surfaces, self cleaning. Other properties improved include time dependent mechanical and thermal properties such as heat distortion, creep, compression set, shrinkage, modulus, hardness and biological compatibility.Type: GrantFiled: March 19, 2007Date of Patent: March 1, 2011Assignee: Hybrid Plastics, Inc.Inventors: Joseph M. Mabry, Timothy S. Haddad, Sarah Anne Mazzella, Sukhendu B. Hait, Joseph J. Schwab, Joseph D. Lichtenhan
