摘要：

A flexible, transparent acoustic actuator and nanogenerator based on graphene/P(VDF-TrFE)/graphene multilayer film is demonstrated. P(VDF-TrFE) is used as an effective doping layer for graphene and contributes significantly to decreasing the sheet resistance of graphene to 188 ohm/sq. The potentiality of graphene/P(VDF-TrFE)/graphene multilayer film is realized in fabricating transparent, flexible acoustic devices and nanogenerators to represent its functionality. The acoustic actuator shows good performance and sensitivity over a broad range of frequency. The output voltage and the current density of the nanogenerator are estimated to be similar to 3 V and similar to 0.37 mu Acm(-2), respectively, upon the application of pressure. These values are comparable to those reported earlier for Zn0- and PIT-based nanogenerators. Finally, the possibility of rollable devices based on graphene/P(VDF-TrfE)/graphene structure is also demonstrated under a dynamic mechanical loading condition.
