Abstract

WS<sub>2</sub> and marine alginate are perfectly coupled to ensure scalable production of exfoliated WS<sub>2</sub> with unprecedented efficiency, further providing super mechanical properties and the photothermal effect to their composites. Combined with the water-intake and cation-binding capabilities of alginate, biomimetic soft devices are designed with stimuli-responsiveness and actuating properties, capable of serving as a photo-driven motor, a walking robot, and a gripper.
