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.
