Experimental studies of barium titanate nanofibers prepared by electrospinning

This paper reports the fabrication and characterization of BaTiO3 nanofibers prepared by the electrospinning method. The X-ray diffraction (XRD) pattern revealed the formation of tetragonal phase corresponding to the Bragg angle 2 theta = 31 degrees and 45 degrees. The formation of metal oxide is confirmed by the FTIR measurement. SEM study evidenced the smooth and randomly grown nanofibers with their average sizes 472 and 515 nm with respect to the samples BT1 and BT2 prepared at 8 and 12 kV dc voltages. TG/DTA analysis was performed to study the heating behavior of the composite BaTiO3/PVP mat and 49 % weight loss was observed at 725 degrees C.
