Abstract

TiO2 nanofibers have been succesfully produced by Electrospinning Method. The purpose of this research is to find out the influence of voltage variety towards morphology, fiber diameter size and structure of TiO2 nanofibers crystal. TiO2 synthesis is done by using sol-gel method. This research use TTIP materials as precursor, ethanol as solvent, acetic acid as catalyst and PVP as polymer of fibers formation. The variety of voltage which have been used such as 16, 18,22, and 24 kV. Electrospinning process is done through the distance of tip to the collector by 13 cm with 1,5 ml/hour flow rate and is calcined at temperature of 450o C for 3 hours. The results of TiO2/PVP viscosity measurement obtains value of 2889,96 cP and Nanofibers TiO2/PVP voltage surface at (29 ±3) dyn/cm. Scanning Electron Microscopy (SEM) characterization shows nanofibers morphology which is relatively uniform and rather continuous with the diameter size of fibers decreases along with the increase of electrospinning voltage at fibers diameter size between 194-255 nm. X-Ray Diffraction (XRD) analysis result show that crystal peak formed on TiO2 nanofibers is anatase phase.
