Polymer relaxor ferroelectric (RFE) behavior such as narrow hysteresis loop with low remnant polarization and high saturation electric field has attracted great attention for their excellent application potentials in high energy storage. Poly(vinylidene fluoride-trifluoroethylene-chlorotrifluoroethylene) [P(VDF-TrFE-CTFE)] is a typical relaxor ferroelectric polymer, in which a third unit CTFE with large size and low dipole moment is incorporated as defects to physically confine the ferroelectric domain size into nanoscale to achieve RFE structures. In this study, preparation and characterization of P(VDF-TrFE-CTFE) Langmuir-Blodgett (LB) nanofilms with tunable thickness assisted by amphiphilic poly(N-dodecylacrylamide) (pDDA) nanosheet will be introduced.
