    Abstract: 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.

  • Publication number: 20150060740
    Abstract: 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 an oxidant solution to thereby create an oxidized surface. The resulting iron electrode is thereby 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.
