Abstract:
1. A process for the preparation of metal-coated polymer nano-fibres, comprising the steps of a) preparing a polymer nano-fibre with functional groups comprising epoxy rings on a surface of the polymer nano-fibre and epoxy rings in a structure providing the binding ability to a reducing reagent by electro-spinning at ambient conditions; b) contacting the electrospun polymer nano-fibre obtained in step a) with a reducing agent, thereby opening the epoxy rings on the surface of polymer nano-fibre and replacing with the reducing agent; c) reacting the reducing agent modified polymer film obtained in step b) with a metal salt solution in alkaline media and obtaining an electro-spun mat; and d) treating the electrospun mat obtained in step c) with water to open the epoxy rings in the structure and crosslinking the chains to provide integrity.
