| Description |
Tin oxide (SnO2) nanofibers are successfully prepared by electrospinning homogeneous viscous solutions of tin
acetate in polyvinyl alcohol (PVA) in the ratios of 20:80, 25:75 and 30:70 (by weight). The electrospinning is carried
out by applying a DC voltage of 7 kV to the tip of a syringe and maintaining the tip to collector distance (TCD) of 7 cm, i.e. at DC electric field of 1 kV.cm–1. The electrospun nanofibers are calcined at 1000oC for 2 h. Both as spun and heat treated nanofibers are characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM),
thermogravimetric analysis (TGA), etc. The specific surface area of the as spun nanofibers is 110 m2.g–1. TGA of
nanofibers indicates complete decomposition of the organics at 550oC. XRD analysis of calcined nanofibers confirms the formation of pure tin oxide. SEM study shows cylindrical fibers with diameter in the range of 20-200 nm with aspect ratio 1000. In general, average diameter of the green fibers decreases with the decrease of PVA concentration
or increase of tin acetate concentration.
