Owing to the high aspect ratio and increased fiber-matrix adhesion due to the large surface area to volume ratio, nanofibers can be constructed into lightweight yet strong materials. The development of nanofiber-based power sources may have a
significant impact on the field of electronic smart textiles. With regard to the demand for portable electronics in the form of wearable smart materials, piezoelectric nanofibers are investigated herein. In our previous studies, we have described a
centrifugal electrospinning (CE) system that can produce highly aligned PVDF nanofibers at a large scale [16]. Also, it has been demonstrated that PVDF nanofibers created with the CE system show strong piezoelectric properties when a small stress is applied [17,18]. Here, to amplify the inherent piezoelectric properties of PVDF, nano-sized BaTiO3 particles are incorporated into PVDF fibers at various concentrations to produce highly-aligned nanofibers with enhanced piezoelectric properties.
