Abstract
[C
2 H 5 O) 4 Si+PVP]/ PVP]/[SnCl 4 + Ti(OC 4 H 9 4 CH3COOH+PVP] precursor composite fibers have been fabricated through
self made electrospinning equipment via electrospinning technique. SiO 2 /SnO 2 /TiO 2 composite nanofibers were obtained by
calcination of the relevant precursor composite fibers . The samples were characterized by thermogravimetric differential
thermal analysis (TG DTA), X ray diffractometry (XRD), Fourier transform infrared spectroscopy (FTIR) FTIR), and Scanning electron microscopy (SEM). R esults showed that the precursor composite fibers are amorphous in structure, and pure phase SiO 2 /SnO 2 /TiO 2 composite nanofibers are obtained by calcination of the precursor composite fibers at 800800~900 ℃ for 8 h. The surface of precursor composite fibers is smooth, and solvents, organic compounds and inorganic in the precursor composite fibers are decomposed and volatilized totally, and the mass of the sample kept constant when sintering
temperature was above 800 ºC, and the total mass loss perc entage is 80%..
