Abstract

Different from the traditional ways to prepare PDMS elastomers by addition or condensation curing reaction, a novel strategy is reported by chemical modification and curing with bis-ionic liquid (bis-IL) as a crosslinker in this study. The
IL-modified elastomer (IL-elastomer) presents a relatively low Young’s modulus of ~0.36 MPa and excellent mechanical stability with unchanged Young’s modulus and strain at break after a year. Significant improvement in relative permittivity
(εr =11 at 0.1 Hz), which is ~4 times as high as that of commercial silicone elastomers (~2.8), is proven as well. Furthermore, the dielectric elastomer actuator developed from this elastomer exhibits a maximum area strain of 9 % at 18 V/μm due to the combination of high εr and low Young’s modulus. The outstanding actuation performance of this novel elastomer suggests a promising potential for use in artificial muscles, soft robotics, and energy conversion devices.
