| Abstract Scope |
The synthesis and fabrication of nanofibers can be accomplished by a variety of techniques, depending on the desired morphology and application. One technique, electrospinning, has garnered increased attention for the ability to synthesize nanofibers of varying compositions with an inherently high surface area to volume ratio. This work details the processing-property relationships of barium titanate (BTO) and doped BTO nanofibers synthesized by electrospinning utilizing sol-gel precursors. Although BTO has been heavily investigated in various form factors as a lead-free electroactive, it is critical to recognize that the control of ceramic nanofiber characteristics via electrospinning is a complex effort, made additionally challenging by the sol-gel precursor preparation and chemistry. Here, processing parameters such as flow rate, collector distance and calcination temperature are varied along with modifications to the sol-gel precursor solution chemistry to investigate the effect these changes have on phase purity, fiber morphology, and basic electrical properties. |
