Self‐Poled Sausage‐Like PVDF Nanowires Produced by Confined Phase Inversion as Novel Piezoelectric Nanogenerators

“…[4] Nanogenerators have traditionally [5] been demonstrated with inorganic materials, such as zinc oxide (ZnO) [6,7] and subsequently, gallium nitride (GaN), [8] barium titanate (BaTiO 3 ), [9] and PbZr x Ti 1−x O 3 (PZT). [10] More recently, owing to their flexibility and ease of processing, polymeric ferro/piezoelectric materials, such as nylon, [11,12] poly(vinylidene fluoride) (PVDF), [13,14] and poly(vinylidene fluoridecotrifluoroethylene) (P(VDFTrFE)), [15][16][17][18][19] as well as hybrid nanocomposites [20] have gained significant interest, not only for nanogenerators, but for printable memory devices.…”
