Synthesis and characterization of electrospun BaTiO3/PVP composite nanofibers

In this work Barium Titanate- Polyvinylpyrrolidone (BaTiO₃/PVP) composite nanofibers are synthesized via electrospinning with sol-gel precursor. BaTiO₃ nanofibers are obtained after calcinning the composite at 960 °C for 20 h. The morphology and crystal structure of the electrospun composite nanofibers are characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD) and FT-IR analyses. SEM studies show that the average diameter of the electrospun BaTiO₃/PVP composite nanofibers and BaTiO₃ nanofibers is 379 nm and 170 nm, respectively. XRD results confirm cubic perovskite crystal structure of BaTiO₃ nanofibers and FT-IR spectrum shows the formation of metal oxide bond and other bond in the BaTiO₃/PVP composite nanofibers. The SPSS 16 software backward regression has been used to study the effect of the voltage and flow rate on the diameter of BaTiO₃/ PVP composite nanofibers and to obtain the standard equation governing the production of composite nanofibers.
