Abstract: In this letter, a formation method for uniform ferroelectric polymer thin film on very rough aluminum foil is introduced, and the performance characteristics of the film are characterized by hysteresis measurements. For a bending radius of 0.6 cm, the remanent polarization, coercive field and internal bias field are equal in a flat state. After bending 500 times repetitively with a bending radius of 1.1 cm, its performance was nearly constant. Therefore, the method proposed in this letter can be useful for the fabrication of high-quality flexible memory devices on a flexible and rough substrate.
