    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: The present invention relates to a process for the metal coating of nano-fibres by electrospinning, to the metal coated nano-fibres obtained by this process and to the use of said metal coated nano-fibres. The process is characterised in that a polymer nano-fibre with functional groups providing the binding ability to a reducing reagent is prepared by electrospinning at ambient conditions. Then this is contacted with a reducing agent, thereby opening the epoxy ring on the surface of polymer nano-fibre and replacing with the reducing agent and the reducing agent modified film is reacted with metal solution in alkaline media. Finally the electrospun mat is treated with water to open the epoxy rings in the structure and crosslinking the chains to provide integrity.
