Patent number: 8581158Abstract: An electrically conductive coating composition is provided for use on aircraft and other substrate surfaces to prevent the formation of ice or to melt ice. The conductive coating composition may include a nanomaterial such as carbon nanotubes dispersed in a solvent which may be applied to a substrate surface to form a thin film which is resistively heatable. The conductive coating may also comprise a nanomaterial formed from carbon nanotubes or fullerenes grafted to a polymer containing an active functional group which renders a substrate surface icephobic and is also resistively heatable.Type: GrantFiled: August 1, 2007Date of Patent: November 12, 2013Assignee: Battelle Memorial InstituteInventors: Amy M.

Publication number: 20050196441Abstract: The present invention provides a manufacturing process for quick dissolving products having active ingredients directed to agrochemical applications, such as plant applications and animal and animal health applications. Electrohydrodynamic (EHD) spraying is used to form a product form preferably comprised of fibers that contains a desired agrochemical compound formulated to quickly disintegrate on contact with a solvent such as water. The dispersed chemical is then provided as a sprayable solution. Because the product form contains little or no liquid, significant size and weight savings are gained, higher active ingredient loadings may be placed in a smaller amount of material, and manufacturing, packaging and transportation costs are thereby reduced without impacting user-friendliness. In addition, the EHD manufacturing method of the present invention also permits combining active ingredients previously not capable of effective use together in a single product.Type: ApplicationFiled: November 5, 2004Publication date: September 8, 2005Inventors: James Dvorsky, Brian Graham, Sreedhara Alavattam, Charles Gegenheimer, John Finney, Jean Schelhorn, Dov Rosenberg, Jeffrey Cafmeyer, Mark Bauer, Robert Fellows, Nadim Moucharafieh, Ronald Coffee, Alastair Pirrie, David Davies, Johnathan Essex-Lopresti, Margaret Wan, Anna Busby
