The application provides a preparation method of a composite dielectric elastomer film and a dielectric elastomer film actuator. The preparation method comprises the following steps: step 1: mixing BTRU@CDs giant electro-rheological particles with an electro-rheological liquid dispersion phase to obtain a suspension; step 2: uniformly mixing silicone rubber with the suspension to obtain a composite dielectric elastomer prepolymer, wherein the mass ratio of the silicone rubber to the suspension is 15:1 to 1:1, and the mass ratio of the BTRU@CDs giant electro-rheological particles in the composite dielectric elastomer prepolymer is 5-40%; and step 3: film forming is performed on the composite dielectric elastomer prepolymer to obtain a composite dielectric elastomer film. The composite dielectric elastomer film prepared by the preparation method of the composite dielectric elastomer film has better actuating performance, better mechanical performance and better cycle stability than traditional rubber elastomers. The problems of high driving voltage, large pre-stretching ratio, limited actuating strain, poor fatigue resistance and easy breakdown of existing dielectric elastomer materials are solved.
