摘要:

液晶弹性体(LCEs)是一种可响应外界刺激、并产生可逆驱动的智能高分子材料。在LCEs基体中添加各种功能性材料,所得的复合材料能对光、电和磁场等外界刺激做出响应,极大地扩展了LCEs材料的应用领域。磁场刺激由于具有远程非接触调控、响应速度快、生物安全性高和穿透力强等特点,逐渐引起研究者的兴趣。本文介绍了磁响应LCEs复合材料的研究现状,同时探讨了磁响应LCEs复合材料在相关领域的应用前景。

Abstract:

Liquid crystalline elastomers (LCEs) are excellent polymer materials that can respond to external stimuli. By adding various functional materials into LCEs, the composites can respond to various stimuli such as light, electricity and magnetic field, which greatly expand the application range of LCEs. The magnetic response gradually attracts interests due to its characteristics such as remote non-contact control, fast response, good biocompatibility and strong penetrating power. In this paper, the research status and application prospects of magneto-responsive LCEs are discussed.
