Nanofibers composite vanadium oxide/polyaniline: synthesis and characterization of an electroactive anisotropic structure

This contribution describes the synthesis of a hybrid nanocomposite constituted by vanadium oxide/polyaniline (PAni) with an interesting fibrilar morphology. Nanofibers can be obtained as main reaction products of nanocomposite V2O5/PAni and hexadecylamine after hydrothermal treatment. In general, nanocomposite nanofibers present a typical length varying from 1 to 10 mum and a width varying from 15 to 400 nm. Electrochemical experiments have shown a specific capacity of about 150 A h kg(-1) during the 10 initials cycles, revealing a promissory material for utilization as cathode for ion-Li batteries.
