    摘要: An article having a nanoporous membrane and a nanoporous graphene sheet layered on the nanoporous membrane with the nanoporous membrane and the nanoporous graphene sheet in direct contact. A method of: depositing a layer of a diblock copolymer onto a graphene sheet, etching a minor phase of the diblock copolymer and a portion of the graphene in contact with the minor phase to form a nanoporous article having a nanoporous graphene sheet and a nanoporous layer of a polymer, and removing the nanoporous layer of a polymer.

    摘要: A compound having the formula below. Each R is methyl or phenyl; R2 comprises one or more of silane, siloxane, and aromatic groups; n is a nonnegative integer; and m is 1 or 2. The dashed bond is a single bond and the double dashed bond is a double bond, or the dashed bond is a double bond and the double dashed bond is a triple bond. A polymer made by a hydrosilation reaction of a polyhedral oligomeric silsesquioxane having pendant siloxane groups with an acetylene- and silicon-containing compound having at least two vinyl or ethynyl groups, and a crosslinked polymer thereof. The reaction occurs between the pendant siloxane groups and the vinyl or ethynyl groups.

    摘要: A fiber of linear polymer coated with a siloxane-carborane polymer or a thermoset or ceramic made therefrom. An organic fiber coated with a siloxane-carborane polymer or a thermoset or ceramic made therefrom and a surfactant. An organic fiber coated with a siloxane-carborane polymer made from a hydrosilation reaction of a siloxane-carborane compound containing at least two unsaturated carbon-carbon bonds and a silane compound or a thermoset or ceramic made therefrom. A method of coating a fiber by contacting a fiber to an aqueous solution of a siloxane-carborane polymer and a surfactant or to a solution of a siloxane-carborane polymer in a non-halogenated organic solvent. A method of contacting a fiber to a solution of a siloxane-carborane polymer, drying the coating to a temperature that does not change the polymer to a thermoset or ceramic, and using the dried, coated fiber in a process that requires that the fiber be flexible.

    摘要: A carborane-siloxane compound is provided having the repeat unit Q contains any of —SiR2—, —SiR2—O—, —C≡C—C≡C—, carboranyl, and U′. Each R and R′ is alkyl, aryl, alkylaryl, haloalkyl, haloaryl, or mixtures thereof. Each U′ is derivable from hydrosilation of an alkenyl or alkynyl group. Each T is alkyl, aryl, alkylaryl, haloalkyl, haloaryl, mixtures thereof, —(O—SiR′2)xH, or the repeat unit. Each x and x′ is a positive integer. The compounds may be made be reacting a carborane-siloxane precursor having unsaturated end groups with a siloxane crosslinker in the presence of a hydrosilation catalyst.
