Abstract

We demonstrate spin-cast ultrathin poly(vinylidene fluoride-co-trifluoroethylene), P(VDF-TrFE), films on flexible and transparent substrates. Importantly, the PEDOT:PSS electrode allowed for the superior piezoresponse value (17.14 ± 2.37 pm V−1) and the low coercive voltage (1.76 ± 0.79 V) of the 20 nm thick P(VDF-TrFE) films. The use of PEDOT:PSS allows for the coherent interface between PEDOT:PSS and P(VDF-TrFE), the strong adhesion at the interface and no interfacial interaction when compared to that of indium–tin oxide (ITO).
