    摘要： The present invention relates to an actuator which is one of the energy conversion devices, and is characterized by improving the ability to convert electrical energy into mechanical energy by way of using a dielectric elastomer composite comprising a filler with an efficient dispersibility. In case of using a conventional resilient dielectric layer, there was a problem in that the operating voltage is high, while advantageously exhibiting a fast response and a high strain. The present invention can provide dielectric elastomer composite actuators that show excellent electromechanical conversion properties, by adding a dispersing agent such as a pyrene derivative or a polymeric compound having an amine end group when preparing the composite wherein carbon-based conductive fillers such as carbon blacks, single-walled carbon nanotubes (SWCNTs), double-walled carbon nanotubes (DWCNTs), multi-walled carbon nanotubes (MWCNTs) and graphenes, or high dielectric fillers such as copper phthalo-cyanine (CuPc), MOFs (metal organic frameworks) and barium titanate (BaTiO3) are comprised in a thermoplastic resilient dielectric layer to enhance the dispersibility of the fillers.
