摘要 单畴结构的液晶弹性体具有自发可逆形变特性,是一种新型的智能材料,在传感器、微执行器等领域具有重要的应用价值.分别综述了热致型、光致型自发可逆形变液晶弹性体的研究发展现状,分析和阐述了单畴液晶弹性体自发可逆形变特性的原理,并展望了单畴液晶弹性体在人工肌肉和形状记忆材料方面的应用前景. The progress in monodomain liquid crystal elastomer (LCE), a novel smart material, is reviewed in this paper. The physical principle of spontaneous reversible shape change of monodomain LCE is analyzed. Then, the LCEs with thermal-mechanical effect and LCEs with photo-mechanical effect and their potential applications in artificial muscle and shape memory materials are investigated.
