Dielectric elastomer actuator with excellent electromechanical performance using slide-ring materials/barium titanate composites - Journal of Materials Chemistry A (RSC Publishing)
Dielectric elastomers are referred to as artificial muscles because of their excellent properties. However, the need for high operating voltage limits their practical application. A reduction of the operating voltage can be achieved with novel elastomers offering intrinsically high electromechanical sensitivity. In this work, slide-ring materials with a necklace-like molecular structure are prepared as dielectric elastomer materials. These slide-ring materials are found to exhibit high dielectric constants, low elastic moduli, and high electromechanical sensitivity due to their special structural characteristics. Barium titanate particles modified by γ-methacryloxypropyl trimethoxy silane (KH570) are incorporated into the slide-ring materials to further improve the actuated performance of the slide-ring materials.
