Based on liquid crystal elastomer (LCE) materials,
hierarchically structured soft actuators can meet some requirements for “human-friendly” working mode and execute
complex tasks with intelligent adaptation to environmental
changes. However, few researchers have paid much attention to
the preparation methods of multicomponent/hierarchical LCE
actuators. In this communication, we demonstrate the successful integration of an exchangeable diselenide chain extender for
the preparation of dynamic LCEs, which could be reprogrammed on heating or under visible light illumination. Moreover, the rearrangeable polydiselenide networks could be
applied to develop the self-welding technology toward fabricating hierarchically structured LCE actuators with sophisticated deformability without using any auxiliary reagent
(adhesive, tape, catalysts or initiator) during the assembling
process
