摘要：Liquid crystal elastomers (LCEs), a class of intelligent soft materials that combine the tunable molecular ordering of liquid crystals (LCs) with the large, reversible deformability of elastomers, are capable of undergoing reversible macroscopic shape changes in response to external stimuli, and have been considered ideal material platforms for flexible actuation systems such as soft robots, artificial organs and wearable devices. With the rising demands in realizing bio-mimicking complex and highly environmental adaptable intelligent actuation systems, multi-stimuli responsive LCEs, which integrate two or more responsive mechanisms into programmed deformations, have emerged as a crucial direction for expanding the application boundaries of LCE-based systems. In this review, we present a systematic overview of the latest advances in multi-stimuli responsive LCEs, highlighting key synthetic routes and architectural design strategies that enable dual- and higher-order stimulus coupling. We elucidate the underlying response mechanisms, material architectures, and performance metrics, and summarize representative applications in artificial muscles, soft robots, and medical devices, emphasizing their superior environmental adaptability, precision of functional execution, and capacity to perform complex tasks.
