摘要

驱动器以其优良的性能和广阔的应用前景，在软机器人、人工肌肉等领域引起了广泛的研究兴趣。通过将偶氮苯分子引入到驱动器材料中，并基于偶氮苯分子可逆的光致异构化过程，可以实现无接触、精确控制、低能耗的光响应驱动器。经过多年的发展，偶氮苯液晶驱动器材料历经了从最初的聚硅氧烷类、聚丙烯酸酯类等到先进的动态酯交换网络等。驱动材料的发展进一步促进了驱动形式的多样化和功能化。偶氮苯液晶驱动器的驱动形式从简单的弯曲、螺旋、震荡到更为实用化的光控马达、提拉重物、微量液体运输等。本文总结和评述了偶氮苯液晶驱动器的发展历程、典型应用和目前存在的问题等，最后展望了其在能源转换领域的应用前景。

Abstract

Actuator has aroused enormous research avocation due to its excellent performance and promising applications in the field of soft robots

artificial muscles

etc.

By introducing azobenzene mesogens into the actuation material

a non-contact

precise control

and low energy consumption photo-responsive actuator can be realized based on the reversible photoisomerization process of azobenzene mesogens. After years of development

the materials of azobenzene liquid crystal actuator have gone through the initial polysiloxanes

polyacrylates

etc.

to advanced dynamic transesterification networks. The development of actuation materials has further promoted the diversification and functionalization of actuation forms. The actuation form of the azobenzene liquid crystal actuator ranges from simple bending

twisting

and oscillating to more practical light-controlled motors

lifting heavy objects

micro liquid transportation and etc. This paper summarizes and reviews the development history

typical applications

and current problems of the azobenzene liquid crystal actuator. Finally

its application prospect in the field of energy conversion is prospected.
