Fabrication of TiO2 nanofibers by electrospinning technique

TiO₂ nanofibers were synthesized by incorporating sol-gel and electrospinning techniques using polyvinyl pyrrolidone and titanium tetraisopropoxide sol-gel as precursor. The as prepared composite fibres were of ~300 nm average diameter. Calcination of these composite fibres at 500° C in air resulted in pure anatase titania nanofibres, of 84 nm mean diameter with smooth surfaces, without contamination of the other phases. In contrast, surfaces that are more granular evolved when they were calcined at higher temperatures. The phase of the as prepared as well as annealed samples was revealed by micro Raman investigations.This electronic document is a "live" template.
