▎ 摘  要

The electromechanical property of a diaphragm type actuator comprising a copper phthalocyanine oligomer noncovalent functionalized graphene-polyurethane dielectric elastomer (CuPc-RGO@PU) composite is described. The composite film had a dielectric constant of 102 with a dielectric loss of 0.13 at 3.0 wt% CuPc-RGO filler and 1k Hz. The composite film had a loss modulus of 195 MPa with a loss tangent of 0.4 at glass-transition temperature. At 37 MV/m, the electric field induced strain of CuPc-RGO@PU is more than 2.8 and 2.0 times higher than that of CuPc@PU and RGO@PU. The nanocomposites thus seem to be attractive for Micro-Electro-Mechanical System applications.
