Abstract:A newly developed asymmetric bilayer bending transducer composed of a graphene quantum dot (GQD)-poly(vinylidene fluoride) (PVDF) composite and a simple adhesive tape has been investigated. This bending transducer displays high actuation displacement (10.2 mm) and large electromechanical strain (0.3%) under relatively low electric field strength (20.8 MV m(-1)). The key to the high electromechanical performance lies in the unique GQD-PVDF interfacial structure and the high dielectric constant of GQD-PVDF (2350 at 1 Hz, 1% GQD weight percentage) caused by the interfacial polarization effect. The good electromechanical performance of our device shows bright prospect of GQD in smart materials field.
