Abstract:
High-quality silver (Ag) patterns were inkjet-printed with nanosilver ink on a flexible polyethylene terephthalate (PET) substrate. All-solution-processed flexible ferroelectric polymer devices that use inkjet-printed Ag to create their bottom and top electrodes were demonstrated. The active layer, a poly (vinylidene fluoride-trifluoroethylene) (PVDF-TrFE) thin film, was spin-coated from solution. The devices have a remanent polarization of 8.03 μC cm(-2) and a coercive field of 68.5 MV m(-1), which is comparable to the device with evaporated-Ti electrodes on a silicon substrate. Based on the results presented in this paper, mass production of flexible ferroelectric devices is predictable.
