Multigram preparation of tungsten microfibers via needle-less electrospinning of phosphotungstic acid
Original language description
Metallic tungsten microfibers were prepared in a multigram yield by electrospinning from the aqueous phosphotungstic acid/polyvinyl alcohol (PVA) solution in three steps. Green composite microfibers of H3PW12O40 /PVA were easily electrospun from precursor solutions on a Nanospider instrument with a cylindrical rotating electrode. Subsequent oxidation of the organic PVA matrix and decomposition of phosphotungstic acid in the air at 600°C provided ceramic WO3/P2O5 fibers. Finally, prepared oxide fibers were reduced in a forming gas atmosphere at temperatures up to 1000°C. During the reduction, all phosphorus was removed, and pure metallic tungsten microfibers were produced.
