Abstract

As ideal and smart stimuli-responsive materials for soft actuators, artificial muscles, etc., liquid crystalline elastomers (LCEs) can respond to external stimuli, including heat, light, electricity, magnetism, humidity, etc., and make corresponding deformations. Among these external stimuli, magnetic stimulus is featured by remote and contactless control, fast, precise, extremely strong penetration, safe, easy tunability, and so on. By doping magnetic nanoparticles into LCEs, their actuation and motion can be triggered by magnetic fields or forces untetheredly, remotely, and highly precisely. Therefore, the magnetic nanoparticles endow LCEs with magneto-responsiveness, opening doors to LCEs for many unique potential uses, such as magnetic read-out, magnetic valves, magnetic switches, and so on. This review summarizes recent advances in magneto-responsive LCE nanocomposites. Their fabrication is comprehensively discussed. New properties of magneto-responsive LCEs brought by magnetic nanoparticles are also thoroughly reviewed. Their promising applications are subsequently summarized and explored.
