As a composite material, the magnetic flow in the Magnetorheological elastomer (MRE) becomes elastable particles suspended in the non-magnetic elastomer body. The magnetic field effect can make the material have variable stiffness and damping characteristics, so that it is adaptive and controllable. The biggest disadvantage of traditional MRE is that the width of the operating band is limited and narrow. The present work proposes a new model of seismic isolator based on MRE mixed with carbon Nano-tubes. During the curing process, a multi-wall carbon Nano-tubes (MWCNTs), which provides the adaptive frequency for real-time vibration control under transient disturbance. The adaptability has greatly improved the sustainability of the structures, especially for the high-risk structures of earthquakes. We found that the magnetic flow into the elastic body has more effective functions when mixed with MWCNTs. Compared with the traditional isolators, the magnetic and mechanical properties of the material are improved well, and it is expected to achieve structure optimization and adaptive performance.
