Ferroelectric polymers are a family of crystalline polymers with reversible remanent polarization originating from their unique chemical structures and molecular packing. As an important ferroelectric polymer, poly(vinylidene fluoride) (PVDF) and its copolymers have been exploited for various applications, including nonvolatile memories, energy harvesters, and piezoelectric/pyroelectric sensors. To achieve better performance in PVDF-based devices, crystallization manipulation and controllable nanostructure formation are unavoidable and are of crucial importance. For this review, recent exploitation of the control of PVDF ferroelectric polymer crystallization at the nanoscale was specifically examined and summarized to provide insight into the future development of ferroelectric polymer nanomaterials.
