- Description
- Soft actuators have great potential applications in sophisticated movement and sensitive devices due to their flexible nature, good interaction, and precise control. However, existing carbon-based optical actuators are limited in their response under visible light irradiation. The limited visible light absorbance of the carbon nanostructure brought the metallic nanoparticle into the soft actuators that can absorb visible light. This study introduces a new type of plasmonic photothermal-bimorph actuator, using graphene oxide (GO), reduced graphene oxide (rGO), and silver nanorods (Ag NRs) to overcome the limitations of traditional optical actuators. The bimorph film is actuated by visible and near-infrared light stimuli with various power densities showing reversible deformation behavior. The actuator shows significant bending associated with a ?50 change in bending angle under visible light irradiation with a response time of ?5 1 sec. Furthermore, a smart photo-controlled non-contact switch is fabricated based on photo-thermal conversion properties, demonstrating perfect integration of plasmonic bimorph actuators. The density functional theory based molecular dynamics calculations provide an additional understanding of the bending of actuators under external stimulus. Using illustrative demonstrations of actuators, these results hint at a method for generating multipurpose visible light-based soft robots, supporting a new approach to developing an optical locking system. 2024 Wiley-VCH GmbH.
