摘　　要：磁流变弹性体是一种新型智能材料,力学性能等随外加磁场可控。磁流变弹性体兼有磁流变材料和弹性体的优点,如响应快、可逆性好、可控能力强等,又克服了磁流变液沉降、稳定性差、需要密封装置等缺点,在减振降噪、智能感应等领域具有广阔的应用前景,因而近年来成为磁流变材料研究的一个热点。磁流变弹性体根据基体与磁性颗粒的不同,可以分为很多种,本文综述了近年来国内外磁流变弹性体在制备与应用方面的研究与最新发展。Magnetorheological elastomer （MRE） is a new kind of smart materials, with controllable mechanical property in presence of external magnetic field. MRE possesses advantages of both magnetorheological （MR） material and elastorner, such as rapid response, good reversibility, strong controllable capacity, and overcomes the disadvantages of sedimentation, poor stability, sealing problern of magnetorheological fluid （MRF）, which makes MRE have broad application prospects in the fields of vibration attenuation, noise control and smart sensing and becomes a hotspot of MR materials in recent years. MRE can be divided into many types based on the difference of matrix and magnetic particle, and recent advance in preparation and application of MRE around the world was reviewed in this paper.
