All-polymer, transparent ferroelectric devices, based on the functional polymer poly(vinylidene fluoride trifluoroethylene) [P(VDF-TrFE)], have been fabricated on flexible substrates. The performance of the all-polymer devices was studied and compared to devices with metal electrodes. Specifically, poly(3,4-ethylenedioxythiophene):poly(styrene sulfonic acid) [PEDOT:PSS] and platinum (Pt) electrode effects on the morphology, crystallinity and orientation of P(VDF-TrFE) films were investigated. The devices with PEDOT:PSS electrodes showed similar hysteresis and switching current response compared to Pt electrodes but with tremendously improved fatigue performance. Further, the devices with PEDOT:PSS electrodes showed lower coercive field and better fatigue performance than values reported for other polymer electrodes used with P(VDF-TrFE) on flexible substrates. © 2011 Elsevier B.V.
