Abstract

WS₂ and marine alginate are perfectly coupled to ensure scalable production of exfoliated WS₂ 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.

Keywords: alginate; biomimetics; nanohybrids; stimuli-responsive; transition-metal dichalcogenides.
