Abstract
This paper presents a comprehensive study of the effects of titanium dioxide (TiO2) on the dielectric, mechanical, and electromechanical properties of a silicone elastomer. The silicone/TiO2 composite films exhibited, in comparison with pure silicone, a steadily improvement of dielectric constant and elastic modulus with the augment of TiO2 particles. A transverse planar strain of 18% with pre-strain of 5% at 50V/μm was obtained, which was 50% higher than the corresponding value generated with the pure silicone. The practical actuated strain was lower than the theoretical, and it was well explained.
