摘要： The present invention relates to metal coated nano-fibers obtained by a process that includes electrospinning and to the use of said metal coated nano-fibers. The process is characterized in that a polymer nano-fiber 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-fiber 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.
