Effect of Voltage and Distance on Synthesis of Boehmite Nanofibers with PVP by the Electrospinning Method

In this paper the effect of different voltages and distances on quality of boehmite nanofibers fabricated by the electrospinning method was investigated.For this purpose, boehmite nanoparticles were synthesized using aluminum nitrate precursor and ammonia.The resulted product was electrospined by applying the voltage range of 8-14 kV.Various analyses such as XRD, SEM and nanofibers diameter size distribution were applied to study the characteristic properties of boehmite nanoparticles and nanofibers.The results of these analyses represented that electrospinning of boehmite nanoparticles with specific surface area of 256 m 2 /gr and crystallite size of 7 nm by applying optimum voltage of 10 kV and distance of 10 cm, can produce homogeneous boehmite nanofibers without any nodes.Also, by increase of the applied voltage in the electrospinning process, the diameter of produced nanofibers increased, but on the other hand fiber uniformity also increased.
