Large effective piezoelectric response from the spontaneously polarized surface layer in P(VDF-TrFE) arch films

In this work, we show that a [Formula: see text]150 pC/N can be obtained in nonpoled poly(vinylidene fluoride trifluoroethylene) (P(VDF-TrFE)) copolymer films with an arch structure. The copolymer films, which are often thought to be homogeneous, are in fact inhomogeneous in microstructure and physi...
