Silicone rubber dielectric elastomer has attracted wide attention in the field of dielectric elastomer research due to its low modulus

fast strain response

high rebound rate

and wide temperature adaptability. They have very broad application prospects. However

it has the disadvantages of low dielectric constant and small amount of electric deformation. In response to this problem

this study uses silicone rubber as the matrix and carbon black as the filler. The carbon black/silicone rubber is prepared by controlling the variation range of the carbon black mass fraction within 0%~ 20% and the thickness variation within 0.5mm~2mm. Dielectric elastomer composite material

and test its mechanical and dielectric properties. The results show that adding carbon black filler to the silicone rubber matrix increases the dielectric constant and keeps the dielectric loss in a relatively low range by changing the mass fraction of the added carbon black. When controlling the thickness of the material

it is found that when the thickness is 1.5mm

the fracture strength of the composite material is relatively large

while the elastic modulus is relatively low

which is conducive to the deformation of the material.
