Abstract
The invention relates to a method for producing metal oxide fibers with diameters on the micro- and nanometric scale by using electrospinning. At least one polymer is dissolved in a solvent, a metal salt is dissolved in this polymer solution, and this mixture is subsequently electrospun into fibers. Breaking down the polymer renders metal oxide fibers accessible that can be optionally reduced into the corresponding metal fibers.
Claims10
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.
