Synthesis and Characterization of Alumina/Titania Nanofibers

Both alumina and titania nanofibers are promising materials for use in high-temperature applications. In an attempt to access the properties of these two materials systems simultaneously we synthesize alumina/titania nanofibers by electrospinning. We characterize their properties using different analytical methods (scanning electron microscopy, thermogravimetric analysis, X-ray diffraction, and infrared, and X-ray photoelectron spectroscopies). We compare the properties of these mixed fibers with pure alumina and pure titania nanofibers and investigate the effects of annealing.
