Local piezoelectric response of single poly(vinylidene fluoride) electrospun fibers

resumo

It is shown that electrospun poly(vynilidene fluoride) nanofibers are fully poled right after preparation and show beta-phase contents of similar to 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. (C) 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
