Abstract

Porous material performs good deformation compression and has been widely used in soft actuators and sensors. In this study, a new kind of magnetorheological (MR) sponge was prepared by combining carbonyl iron particles with polyurethane porous structure. The static compressive property of MR foam was studied using a commercial rheometer. The relationship between magnetic particle composition, magnetic field and rheological properties was summarized and analyzed. The research contributes to a deeper understanding of magnetorheological sponge materials, and provides inspiration and theoretical basis for the design of soft actuators ,which may provide inspiration for novel application field.
