  • Publication number: 20070218281
    Abstract: 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.

  • Publication number: 20070166464
    Abstract: The present invention relates to a process for preparing super-hydrophobic surface compositions, to compositions obtained by said process and to the use of said compositions. The process comprises these steps of a) radical or condensation polymerisation of a reactive functional group containing monomer pair with an initiator in non-reactive solvent environment, and b) mixing the copolymer obtained in a) with a hydrocarbon/fluorinated/siloxane chemical agent having at least one end capped with reactive groups and a catalyst characterised in that it further comprises the step of c) electrospinning/electrospraying of the mixture obtained in b), and d) annealing and crosslinking of the electrospun/electrosprayed mixture.
