  • Patent number: 8142843
    Abstract: Aerogel particles having a mean particle size less than 1 micron, products containing the same, processes of making the same, and uses thereof are described. A process of making the particle is also described wherein starting aerogel particles are homogenized or wet milled. The starting aerogel particles can be surface treated during the milling process to prevent agglomeration or aggregation. The aerogel particles can be used in a variety of products and applications.

  • Publication number: 20120020106
    Abstract: A particle containing a hydrophobic region and a hydrophilic region, products containing the same, a process of making the same, and uses thereof are described. A process of making the particle is also described wherein UV/Ozone techniques can be used to control the depth of organics removal from a porous hydrophobic particle such as an aerogel. The particles can be used in a variety of applications, such as a monolith, a building block, an optical waveguide, a blanket, a matting agent, a structural composite panel, a glass-fiber reinforced panel, a window, a separation wall, a composite wall, a temperature insulation panel, a sound insulation panel, a moisture resistant article, a syntactic foam, or any product of manufacture containing the particles.

  • Publication number: 20100216911
    Abstract: The present invention relates to a method of preparing polymer compositions comprising modified metal oxides in a polymer wherein a nanoparticle dispersion of a metal oxide in a non-aqueous solvent is combined with at least one coupling agent to form a nanoparticle dispersion of a modified metal oxide in the non-aqueous solvent. The nanoparticle dispersion is then combined with a polymer followed by the removal of the non-aqueous solvent or, alternatively, combined with a monomer, which is polymerized to form the polymer and removal of the solvent, in any order. Also disclosed are polymer compositions prepared by this method.

  • Publication number: 20080287561
    Abstract: Composites, such as syntactic foams, are described. The composite contains at least one polymer and at least one aerogel. The aerogel is coated with a coating substance to at least substantially prevent the intrusion of the polymer into the pores of the aerogel. Methods of making the composite are also described, as well as uses of the composite.

  • Patent number: 7332264
    Abstract: The present invention provides a mesoporous material comprising at least one region of mesoporous material patterned at a lithographic scale. The present invention also provides a method for forming a patterned mesoporous material comprising: coating a sol on a substrate to form a film, the sol comprising: at least one photoactivator generator, at least one material capable of being sol-gel processed; and exposing the film to light to form a patterned mesoporous material.
