Recent progress of liquid crystal elastomer soft actuator
Liquid crystal elastomer(LCE)smart materials have been widely studied from basic science to technical application due to their features such as reversibility,flexibility,superior environmental adaptation and versatility.In this paper,we mainly review the design and preparation of LCE films and fiber soft actuators in recent years,and the latest research progress in artificial muscles,soft robots and smart textiles.The basic design and synthesis strategy of LCE fiber composite soft actuators are revealed.Their unique properties,underlying mechanism and potential applications are described.Finally,a brief conclusion is summarized and the opportunities and challenges in materials and chemistry science based on LCE soft actuators are summarized.This paper will provide new insights for the development of LCE intelligent materials in the fields of soft robotics,flexible electronics,advanced energy and smart wearables,and promote the rapid development of interdisciplinary disciplines such as nanoscience,synthetic chemistry,materials science and device integration.
