Enabling large actuated strain at low electric field by grafting cyanoester dipoles onto a poly(styrene-b-butadiene-b-styrene) elastomer using thiol-ene click chemistry

Abstract A dielectric elastomer can undergo a large deformation when it is subjected to an applied electric field. As a result, it finds potential usage in artificial muscles, soft robotics, and medical devices. However, current dielectric elastomers suffer from low dielectric constants (e.g.,
