Advanced manufacturing techniques and structure design of liquid crystal elastomer smart materials

Abstract： Liquid crystal elastomer is a type of soft smart materials composed of liquid crystal mesogens and polymer networks. Under external stimuli such as heat，light，or electric field，liquid crystal elastomers can undergo large reversible deformation，showing great potential in applications of soft robotics，artificial muscles，self-sensing systems，and biomedical devices. In recent years，with the development of various manufacturing technologies，researchers have extensively explored the processng methods and structure design of liquid crystal elastomers. This paper first introduces three conventional preparation strategies for liquid crystal elastomers，discussing their features and limitations.Then，we summarize the recent research advances in the manufacturing technologies of liquid crystal elastomers.We further introduce the strategies to utilize the structure design of liquid crystal elastomers to achieve multiple motion modes and rapid actuation. Finally，we discuss the current challenges and future development of liquid crystal elastomers.

1引言

液晶是介于各向同性液體和有序固體狀態(tài)之間的一類物質(zhì)狀態(tài)，既具有液態(tài)的流動性，又保留一維或二維分子排列的有序性，呈現(xiàn)出特殊的物理性質(zhì)。（剩余40750字）
