Abstract
Abstract. Titanium Dioxide (TiO2) nanofibers have been prepared using the electrospinning method. This study aims to determine the morphology and crystal structure of the TiO2 nanofibers and to determine the effect of viscosity on the morphology and crystal structure formed. This study used titanium tetraisopropoxide as a precursor, ethanol as a solvent, acetic acid as a solution stabilizer and controlled the hydrolysis reaction of the precursor, and PVP as a fiber-making material. The amount of variations of acetic acid is 2; 2.5; 3; 3.5; and 4 ml respectively. The results of the viscosity test showed that the greater the acetic acid used, the smaller the viscosity. The electrospinning process was carried out at a high voltage of 13 kV with a flow rate of 1.5 ml/hour. The fiber obtained was then calcined at 450 oC for 3 hours. The calcined sample was then analyzed using X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), and Transmission Electron Microscopy (TEM). SEM characterization results on samples B, C, and D showed that the sample diameters were 313 ± 28 nm, 275 ± 57 nm, and 242 ± 59 nm, respectively. The results of XRD characterization on sample D showed that the resulting sample had a tetragonal crystal structure with a mixed phase between anatase and rutile. The results of TEM characterization in sample D showed the fiber diameter with a size of 68.05 nm. Keywords: nanofibers, TiO2, electrospinning, viscosity.
