Description
A light-responsive supramolecular ink based on a melt-processable polythiourethane liquid crystal elastomer is developed for direct ink writing 4D-printed soft actuators where photocuring is not needed. The light-fueled actuators can be addressed in air and underwater due to combined photothermal and photochemical effects. Using the freedom provided by printing allows for the generation of complex responsive objects.
