2.2. Electrospinning of PAN/TiO2 webs
5% w/w. PAN/DMF solutions containing different amounts of TiO2
(0, 1, 2, and 3 wt.%) were prepared. As for example: to prepare 5%
w/w. PAN/DMF/1 wt.% TiO2 solution, 0.5 g PAN was added into 9.5 g
DMF, followed by 0.1 g TiO2 and stirred. For electrospinning, the
prepared solution was injected into a 1 ml. syringe having a 24 gauge
needle (diameter~0.26 mm.). In set up, syringe was tilted 60 degree
