Abstract

It is shown that electrospun poly(vynilidene fluoride) nanofibers are fully poled right after preparation and show β-phase contents of ∼70%, therefore being able to be implemented into electroactive devices without further processing steps. Further, the local piezoelectric properties of individual electrospun fibers have been studied by piezoresponse force microscopy. Piezoelectric response, polarization switching, and nanoscale patterning of the fibers have been demonstrated.
