Title:
New Molecular Insight into Ferroelectric Polymer and Nanocomposites
Abstract:
Low-cost, light weight, flexible relaxor ferroelectric polymers and nanocomposites enable flexible, wearable and biocompatible devices in acoustic sensors, transducers and actuators. In this talk, we first present our discovery of morphotropic phase boundary-like behavior in ferroelectric P(VDF-TrFE) copolymers which exhibits the state-of-the-art piezoelectric coefficient of -63.5 pC/N. Moreover, we reveal the origin of relaxor behavior in ferroelectric polymers. Finally, we are dedicated to address recent emerging advance especially achieved by scanning probe microscopy which has been used to characterize the interface in terms of different polymer matrix, fillers and filler size. We also focus on fundamental insights into ferroelectric polymers and nanocomposites which is essential to rational design of the state-of-the-art electronics and energy storage devices.
