Abstract
In this study, we prepare uniaxially aligned piezoelectric P(VDF-TrFE)/BaTiO 3 composite nanofibers via far-field electrospinning, and investigate their morphologies and piezoelectric properties preliminarily. The morphology is characterized by both an optical microscope and a scanning electron microscope (SEM). The composition of P(VDF-TrFE) and BaTiO 3 is confirmed by X-ray diffraction (XRD) analysis. The composite nanofibers show high piezoelectric property. In addition, two demonstrations are conducted by a PDMS packaged nanofiber sensor, which can detect the bounces of a water droplet (~6 mg) on a hydrophobic surface and illustrate the pyroelectric effect of the composite nanofibers, respectively.
