The organic matrix can contain one or more organic solvents, such as the combination of one or more hydrocarbons, one or more alcohols, one or more amines, and one or more organic acids. Optionally, the nanoparticle paste formulations can contain about 0.01 to about 15 percent by weight micron-scale metal particles or other additives.Type: GrantFiled: February 11, 2013Date of Patent: April 14, 2015Assignee: Lockheed Martin CorporationInventors: Alfred A.

Publication number: 20150083961Abstract: Electrically and/or thermally conductive polymer composites and methods of preparing same are provided. In some embodiments, a method for preparing an electrically and/or thermally conductive polymer composite may include (1) mixing a polymer, a conductive particulate filler, and a solvent compatible with the polymer to form a non-conductive polymer solution or melt; (2) processing, the non-conductive polymer solution or melt to form a non-conductive polymer network composition; wherein the presence of solvent during three-dimensional network formation manipulates the polymer network structure; and (3) removing the solvent from the non-conductive polymer network composition to form an electrically and/or thermally conductive polymer composite. The altered polymer chain structure present in the non-conductive polymer network composition is maintained in the composite, and offsets the impact of particulate filler addition including increased modulus, decreased elasticity, and decreased elongation at break.Type: ApplicationFiled: September 26, 2013Publication date: March 26, 2015Applicant: U.S. Army Research Laboratory ATTN: RDRL-LOC-IInventors: Randy A.

Publication number: 20150060739Abstract: Provided is a process for preparing an electrode comprising an iron active material. The process comprises first fabricating an electrode comprising an iron active material, and then treating the surface of the electrode with water to thereby create an oxidized surface. The resulting iron electrode is preconditioned prior to any charge-discharge cycle to have the assessable surface of the iron active material in the same oxidation state as in discharged iron negative electrodes active material.Type: ApplicationFiled: September 5, 2014Publication date: March 5, 2015Applicant: Encell Technology, Inc.Inventors: Randy Gene OGG, Michael RODERS, Michael MEESE
