Experimental studies of barium titanate nanofibers prepared by electrospinning

This paper reports the fabrication and characterization of BaTiO$_3$ nanofibers prepared by the electrospinning method. The X-ray diffraction (XRD) pattern revealed the formation of tetragonal phase corresponding to the Bragg angle $2 \theta = 31^\circ$ and $45^\circ$. 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 BaTiO$_3$/PVP mat and $49\%$ weight loss was observed at $725^\circ$ C.
