Abstract

Abstract

Liquid crystal elastomers (LCEs) containing dynamic cross-linking bonds are capable of undergoing macroscopic motion through alterations in volume or shape in response to external stimuli, including light, electricity, or heat. These materials demonstrate remarkable molecular cooperative effects and adaptive properties, offering considerable potential in the fields of soft robotics, artificial muscles, and microfluidics. Effective control of the internal liquid crystal orientation in LCEs is essential for achieving reversible deformation. The breakage and reformation of dynamic bonds not only decouples the construction of cross-linked networks and orientation control, but also enhances the reprocessing properties of materials, enabling new functionalities like remodeling deformation, self-healing, and shape memory. Therefore, the deliberate design and construction of cross-linked network structures, including the selection of cross-linking agents, their structures, and cooperative effects of various networks, are crucial for producing liquid crystal elastomers with exceptional performance and multifunctional integration. This review comprehensively discusses advancements in the preparation and application of LCEs, encompassing liquid crystal orientation control and single/double dynamic cross-linking networks (involving dynamic non-covalent and covalent bonds), and delineates future prospects for development in this field.
