  • Patent number: 9011710
    Abstract: Methods are disclosed for synthesizing nanocomposite materials including ferromagnetic nanoparticles with polymer shells formed by controlled surface polymerization. The polymer shells prevent the nanoparticles from forming agglomerates and preserve the size dispersion of the nanoparticles. The nanocomposite particles can be further networked in suitable polymer hosts to tune mechanical, optical, and thermal properties of the final composite polymer system. An exemplary method includes forming a polymer shell on a nanoparticle surface by adding molecules of at least one monomer and optionally of at least one tethering agent to the nanoparticles, and then exposing to electromagnetic radiation at a wavelength selected to induce bonding between the nanoparticle and the molecules, to form a polymer shell bonded to the particle and optionally to a polymer host matrix. The nanocomposite materials can be used in various magneto-optic applications.

  • Patent number: 8741432
    Abstract: Coated particles comprise a core of fumed or precipitated inorganic metal oxide having a surface area of about 50 to about 500 square meters per gram and a shell consisting of an array of fluoroalkyl molecular chains at a density of at least 1 chain per square nanometer, joined to the core by covalent chemical bonds and with a total organic content of at least 9.9 percent by weight. These particles are formed by the chemical attachment of fluoroalkyl-alkylsilanes after exposure to an alkylamine and followed by an extraction to remove any organic material not covalently bound. The dense packing of molecular chains in the fluoroalkyl shell combined with a mesoporous structure imparts a very low surface energy, a very high specific surface area, and surface texture over a wide range of length scales. Such features are highly desirable for the creation of, for example, superhydrophobic and superoleophobic surfaces, separation media, and release films.

  • Patent number: 8685159
    Abstract: An adhesion bond strength enhancer for cementitious adhesive mortar is disclosed. The adhesion enhancer improves bond strength between the mortar and relatively hydrophobic plastic material, such as extruded polystyrene boards and expanded polystyrene boards of the type generally employed in Exterior Insulation Finishing Systems (“EIFS”). Preparation of non-caking, free-flowing, solid dialkyl sulfosuccinate compositions for use as the adhesion enhancer is also disclosed. The adhesion enhancer is attractive for large-scale application in mineral mortar dry-mixes or other solid construction materials. The invention can be used to improve the strength of an adhesive bond between a) gypsum based plaster or stucco and concrete or bricks, b) tile adhesives and concrete, and c) mineral mortars on polystyrene boards, among others.

  • Patent number: 8568617
    Abstract: Provided is a method of producing an electrode material precursor having a core-shell structure in which the particle size is extremely small and the particle diameter is uniform, and a method of efficiently producing an electrode material using the obtained precursor. The method is for producing an electrode material precursor having a core-shell structure in which an active material core is coated with polyaniline, wherein an oxidizing agent is added to a solution containing aniline and an active raw material to generate fine active material particles, and aniline is polymerized at the surface of the fine particles. An electrode material having a core-shell structure in which an active material core is coated with carbon is produced by subjecting the electrode material precursor obtained in the foregoing production method to heat treatment in a reduction atmosphere at 300 to 900° C.

  • Patent number: 8557336
    Abstract: Methods and apparatus for coating particulate material are provided. The apparatus includes a vessel having a top and a bottom, a vertically extending conduit having an inlet in the vessel and an outlet outside of the vessel, a first fluid inlet in the bottom of the vessel for introducing a transfer fluid, a second fluid inlet in the bottom of the vessel for introducing a coating fluid, and a fluid outlet from the vessel. The method includes steps of agitating a material, contacting the material with a coating material, and drying the coating material to produce a coated material. The invention may be adapted to coat aerogel beads, among other materials. A coated aerogel bead and an aerogel-based insulation material are also disclosed.

  • Publication number: 20130251900
    Abstract: Refractory metal and refractory metal carbide nanoparticle mixtures and methods for making the same are provided. The nanoparticle mixtures can be painted onto a surface to be coated and heated at low temperatures to form a gas-tight coating. The low temperature formation of refractory metal and refractory metal carbide coatings allows these coatings to be provided on surfaces that would otherwise be uncoatable or very difficult to coat, whether because they are carbon-based materials (e.g., graphite, carbon/carbon composites) or temperature sensitive materials (e.g., materials that would melt, oxidize, or otherwise not withstand temperatures above 800° C.), or because the high aspect ratio of the surface would prevent other coating methods from being effective (e.g., the inner surfaces of tubes and nozzles). The nanoparticle mixtures can also be disposed in a mold and sintered to form fully dense components.
