摘要：
With excellent stability, flexibility, and piezoelectricity, poly(vinylidene fluoride) (PVDF) and its copolymer [P(VDF-TrFE)] have received much attention. However, the applications for its ferroelectricity still suffer the drawbacks of relative low remanent polarization (P (r)) and high coercive electric field (E (c)). In this work, P(VDF-TrFE) composite films were fabricated with the additive of organic perovskite ferroelectric MDABCO-NH4I3. Compared with pure P(VDF-TrFE), the P (r) increases from 7.17 to 12.7 mu C cm(-2), while E (c) decreases from 516 to 324 kV cm(-1) as well as increased permittivity from 15.6 to 37.0. These may provide an alternative way for ferroelectric memory, sensors, and energy storage devices.
