Recently, the development of liquid crystalline network (LCN)-based soft robots is actively progressing, and various attempts are being made to achieve versatile movements. 3D assembly of the LCN building blocks and their shape reconfiguration have been studied to achieve advanced complex locomotion. However, there are still challenges in disassembling and reassembling complex 3D structures once fabricated. Herein, we demonstrate the preparation of photo-controllable LCNs (pc-LCNs) comprising static and dynamic covalent dual-crosslinks for transformable soft robotics. The pc-LCN films exhibit UV-controllable reversible assembly/disassembly and shape reconfiguration capabilities, while still maintaining visible light-responsive actuation behaviors. Such characteristics eventually lead to monolithically assembled, transformable 3D architectures. Also, by adopting selective visible light-responsive dopant dyes, versatile robotic locomotion of 3D soft transformable robots are realized. |
