The effect of various electrospinning parameter and sol-gel concentration on morphology of silica and titania nanofibers

Abstract Nano scale fibers of SiO 2 and TiO with various compositions viscosity parameter have been prepared by electrospinning the precursor tetraethyl orthosilicate (TEOS) titanium (IV) isopropoxide (TiP). Different concentrations polymer polyvinylpyrrolidone (PVP) applied voltages were studied. Distance tip to collector 15 cm flow rate 0.003 mL/h fixed for entire process. The morphology nanofibers was evaluated versus different solution as well voltages. Concentration focused in this study included 5 %wt, 10 %wt PVP along kV – 17.5 applied. as-spun characterized SEM. Results showed that average fiber diameter decreases decreasing concentration.
