Patent ID: 7981354

Claim:
Method for the production of metal oxide fibers with diameters in the range of micro- or nanometers through electrospinning of mixtures of at least one polymer and at least one metal salt in a solvent, wherein subsequently the following steps are carried out: production of a solution of the at least one polymer and the at least one metal salt in a solvent, wherein the ratio polymer to metal ranges between 3:1 and 1:1 (w/w), and wherein the at least one metal salt is an inorganic or organic salt of a metal selected from the group consisting of Cu, Ag, Au, Zr, Hf, V, Nb, Ta, Cr, Mo, W, Mn, Re, Fe, Ru, Ni, Pd, Co, Rh, Ir, electrospinning of this mixture into fibers, removal of the polymer.
