Abstract

Niobium oxide/poly(vinyl acetate) composite nanofibers have been prepared by electrospinning method. Pure ceramic niobium oxide fibers were obtained by high temperature calcination of the organic-inorganic composite nanofibers. The materials have been characterized by scanning electron microscopy (SEM), atomic force microscopy (AFM), X-ray diffraction (XRD) and infra-red (IR) spectroscopy. It has been observed that both the morphology and the crystallinity of the fibers depend on the calcination temperature.
