Fabrication and Electrical Properties of Vanadium Pentoxide Fibres

Abstract:

In this work, orthorhombic vanadium pentoxide (V₂O₅) fibres have been prepared by electrospinning from a sol-gel precursor and the following calcination at 723 K. Structure, composition and morphology of the obtained V2O5 fibres are characterized. The Raman results show that the obtained V₂O₅ fibres don’t undergo a semiconductor-metal transition. And their high temperature electrical properties are discussed according to a thermally activated small-polaron hopping process.
