  • Patent number: 9777161
    Abstract: Treated, mesoporous aggregates comprising a plurality of coated particles that comprise an inorganic oxide core having a surface area of about 50 to about 500 square meters per gram and a shell or coating consisting of an array of fluoroalkyl molecular chains covalently bonded to the core at a density of at least one chain per square nanometer. The aggregates are formed by the chemical attachment of fluoroalkyl-alkylsilanes after exposure to an alkylamine and followed by an extraction to remove any unbound organic material. 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: 9028966
    Abstract: A method for producing silicone fine particles is provided. The particle comprises a spherical fine silicone elastomer particle and polyorganosilsesquioxane particles attached to the surface of the spherical fine silicone elastomer particle. The polyorganosilsesquioxane particle has a particle size of 200 to 2,000 nm which is smaller than the spherical fine silicone elastomer particle. The method comprises the steps of adding an organotrialkoxysilane to water for hydrolysis, and adding spherical fine silicone elastomer particles having a volume average particle size of 0.5 to 100 ?m, an anionic surfactant, and an alkaline substance to the organotrialkoxysilane hydrolysate and allowing the mixture to stand to thereby promote condensation of the organotrialkoxysilane hydrolysate so that the polyorganosilsesquioxane is deposited on the surface of the spherical fine silicone elastomer particles.

  • Publication number: 20150125600
    Abstract: A process for producing a porous ceramic body comprises a) mixing a coated porogen with a silicate or a oxide ceramic precursor, wherein the porogen is decomposable to gaseous decomposition products and optionally solid products upon heating, and is coated with a coating agent; b) forming a green body from the mixture obtained in step (a); and c) firing the green body obtained in step (b) to obtain the ceramic body, whereby the porogen decomposes to form pores within the ceramic body and the coating agent is deposited at the inner surface of the pores. The porogen is coated with a coating agent which, upon firing, is deposited at the inner surface of the ceramic pores, so that porous ceramics having decreased weight and improved porosity are obtained, while maintaining at the same time good mechanical strength. A green body and a porous ceramic body obtainable with the above-mentioned process are described too.

  • 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.
