Development of self-healing and shape memory elastomers is important for artificial smart materials. Here, a novel shape memory magnetic elastomer with high mechanical strength consisting of conventional polymer and Fe3O4 nanoparticles is reported. The elastomer exhibit superparamagnetism, and superior self-healing performance at elevated temperature. The tensile strength of the healed elastomer can be up to 12.0MPa, and almost equal to that of virginal sample. These materials are capable of remote controlling in shape memory process and actuating behavior, and can be used in many applications, ranging from wireless-controller to actuator or biomedical devices, and other remote shape memory systems.
