摘要

Untethered soft actuators are usually based on 3D engineered special polymers such as liquid crystal networks or hydrogels that require complex fabrication methods. Here, an easy-to-process, anisotropic composite soft actuator based on a simple photothermal dye-doped polyethylene film is presented. The 3D anisotropic polymer films are prepared by solution-casting and subsequent thermal solid-stretching. The resulting soft actuators exhibit large and controllable bending in response to light (UV and/or near-infrared (NIR)) and are able to act as grippers picking up cargo. Additionally, the films are capable of realizing "diving" and "surfing" locomotion in and over a liquid via the photothermal induced Marangoni effect, yielding a NIR light-fueled transporter able to pick up cargo. The results open up new possibilities of using commodity polymers in a broad range of applications including untethered soft actuators and robotic devices.
