  • Patent number: 9005540
    Abstract: Hollow conjugated polyelectrolyte (HCPE) microcapsules contain at least one conjugated polyelectrolyte and at least one other polyelectrolyte of complementary charge and the microcapsule has a hollow core. The conjugated polyelectrolyte is a polymer with a multiplicity of charged repeating units where a portion of the charged repeating units form a pi-conjugated sequence. The complementary polyelectrolyte is a polymer with a complementary charged repeating unit to the charged repeating units of the conjugated polyelectrolyte. The HCPE microcapsules can be formed by successively coating a sacrificial core with alternating layers of complementary polyelectrolytes, at least one of which is a conjugated polyelectrolyte. The sacrificial core can be removed to form the hollow center of a HCPE microcapsule.

  • Publication number: 20150083974
    Abstract: The present invention relates to a new method for preparing a silver-based electrical contact material, comprising following steps of: (a) providing a carbonaceous mesophase solution; (b) adding a silver source into the carbonaceous mesophase solution and stirring to obtain a compound; (c) removing a solvent from the compound to obtain a solid; (d) performing a heat treatment on the solid, and obtaining a silver-based electrical contact material. The silver source is silver powder prepared by means of a chemical method. By means of the method, a uniform carbonaceous coating on silver is implemented, the silver is uniformly distributed in a nanometer scale, and a diamond is generated in situ of a material after being sintered. The silver-based electrical contact material processed by means of this method shows an excellent mechanical wear resistance and electrical property.

    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.
