摘　　要：液晶弹性体作为一种具有可编程、多刺激响应、可逆形变的聚合软物质材料,在软体机器人、软体执行器、柔性电子器件、人造肌肉以及软光子学器件等领域展现出广阔的应用前景。液晶弹性体的多功能应用主要基于可编程的分子取向引起的复杂多重形变,而不同的尺度、不同形貌的液晶弹性体形变对分子取向提出了不同的技术要求。本文综述了液晶弹性体常见的取向方法以及基于不同取向方法的不同尺度和形貌体系的液晶弹性体的多重形变模式,在此基础上,进一步总结了基于可编程复杂形变的液晶弹性体在软体机器人、可调光学器件、智能织物等方面的应用进展,展望了液晶弹性体当前所面临的挑战以及未来发展趋势。Liquid crystal elastomers(LCEs),as a kind of programmable,multi-stimulus responsive,reversibly deformable polymerized soft matter material,currently show great prospects in the fields of soft robots,soft actuators,flexible electronics,artificial muscles,and soft photonic devices.The multifunctional actuations of LCEs are mainly based on the complex multiplex deformations,which are induced by programmable molecular alignments.The realization of high-resolution molecular alignments of LCEs within different thickness systems has advanced requirements for the mesogen alignment technique.In this review article,we discuss the current mesogen alignment techniques and the complex multiplex deformations of LCEs within different morphology systems based on various alignment techniques.We further summarize the advances of LCEs in soft robots,tunable optical devices,smart fabrics and other fields based on programmable complex deformation,and outline the current challenges and future development trends of LCEs.
