  • Patent number: 7211605
    Abstract: An aerogel material with surfaces containing fluorine atoms which exhibits exceptional hydrophobicity, or the ability to repel liquid water. Hydrophobic aerogels are efficient absorbers of solvents from water. Solvents miscible with water are separated from it because the solvents are more volatile than water and they enter the porous aerogel as a vapor across the liquid water/solid interface. Solvents that are immisicble with water are separated from it by selectively wetting the aerogel. The hydrophobic property is achieved by formulating the aerogel using fluorine containing molecules either directly by addition in the sol-gel process, or by treating a standard dried aerogel using the vapor of fluorine containing molecules.

  • Patent number: 7019037
    Abstract: Aerogels having a monolayer coating are described. The aerogel and a monolayer forming precursor are provided in a supercritical fluid, whereupon the aerogel and the monolayer forming precursor are reacted in said supercritical fluid to form a covalent bond between the aerogel and the monolayer forming precursor. Suitable aerogels are ceramic oxides such as silica, alumina, aluminosilicate, and combinations thereof. Suitable monolayer forming precursors include alkyl silanes, chlorosilanes, boranes, chloroboranes, germanes, and combinations thereof. The method may also include providing a surface preparation agent such as water, or hydroetching an aerogel to enhance the coating of the monolayer.

  • Patent number: 7015254
    Abstract: The present invention includes an apparatus for generating an inorganic polymer electret in a colloidal state, the inorganic electret in a colloidal state itself, and applications for the inorganic electret in a colloidal state. The invention includes a method for generation of a colloidal silica particle which is dipolar in that it is positively charged in the nucleus and negatively charged on the outer surface leaving a net negative charge to the particle. The apparatus includes the ability to control particle size, uniformity, consistency, hydration, and three dimensional structure which is desirable for various applications.

  • Patent number: 6929764
    Abstract: Ordered, monodisperse macroporous polymers, their corresponding ordered, monodisperse colloids, and methods of preparing them are disclosed. The methods use an ordered, monodisperse colloidal template to define the polymer pore morphology, which in turn acts as a mold for the growth of a new ordered, monodisperse colloid. The macroporous polymer may be prepared with either spherical or ellipsoidal pores from a wide variety of polymeric systems. The new ordered, monodisperse colloid may be grown from a wide variety of materials including ceramics, semiconductors, metals and polymers. These materials are potentially useful in optical, micro-filtering and drug delivery applications.

  • Patent number: 6716885
    Abstract: A storage-stable aerated gel composition comprising 30 to 97% by weight of water, 0.2 to 5% by weight of a gelling agent selected from xanthan gum, sodium alginate and neutralized carboxyvinyl polymer and 2 to 5% by weight of a fine particulate hydrophobic silicone-treated silica having a surface area of from 80 to 300 m2/g. The composition is in the form of fine particles of an aqueous gel containing the water and the gelling agent, the surface of which particles are coated with a coating of the finely divided particulate hydrophobic silica. The gel composition is prepared by mixing, under high shear conditions, the water and the fine particulate silica, and then adding to the resulting mixture, the gelling agent and mixing under high shear conditions.

  • Patent number: 6680066
    Abstract: The present invention relates to a composite material with an improved structure in which is dispersed an active organic compound, and a method for treating effluents, in particular a method for treating photographic effluents. The composite material takes the form of a structured gel comprising an aluminosilicate polymer matrix in the form of fibers in which at least two distinct fibers are interconnected by at least two covalent bonds to form an irreversible chemical gel and, dispersed in the matrix, an active organic compound. The choice of the degree of cross-linking of the matrix makes it possible to control the diffusion of a hydrophilic active organic compound. The invention further concerns a method for preparing such a composite material.
