Light-Guided Dynamic Liquid Crystalline Elastomer Actuators enabled by Mussel Adhesive Protein Chemistry

Ruixue Liang et al.

Summary: Light-guided soft actuators with dynamic polymer networks have been a topic of interest, but their potential has been limited by synthesis and structure. This study presents a new type of liquid crystalline elastomer (LCE) actuators crosslinked by mussel-inspired catechol-Fe (III) complexes, which are strong, self-healable, shape-reprogrammable, and reprocessable. The formation of catechol-Fe (III) complexes enables outstanding photothermal effects without light-absorbing additives, allowing for programmable actuators with designable structures and shape-morphing capabilities using mechanical force and thermal or light stimuli. The LCE also provides a versatile means to fabricate actuators with different dimensional structures. Furthermore, a crawling robot, C-Bot, demonstrates the potential of LCE in robotic fields, as it can move untethered on solid-substrate and water surfaces based on shape-morphing and Marangoni propulsion mechanisms.

Summary: Inspired by the elongation ability of cells on mimosa petiole, we have developed a shape transformation polymer that can switch between 2D and 3D at room temperature through simple stretching and releasing steps. By patterning the surface of the sample film, we induced different movements of the polymer chains along the thickness, resulting in shape transformation.

A Photoorganizable Triple Shape Memory Polymer for Deployable Devices

Jiahao Sun et al.

Summary: Developing deployable devices using stimuli-responsive materials, such as the photoorganizable triple shape memory polymer (POTSMP) described in this study, allows for programmable deformation and in situ repair to extend service life in aerospace applications. The POTSMP can achieve arbitrary programming of temporary shapes and precise shape recovery under UV and visible light, while also enabling rapid light-reconfiguration for localized repair and process of permanent shape. Combining these operations facilitates the manufacturing of deformable devices with complex structures without the need for special molds.

Phototunable, Reconfigurable, and Complex Shape Transformation of Fe3+-Containing Bilayer Polymer Materials

Lei Wang et al.

Summary: This study demonstrates a new paradigm for designing materials that can mimic complex shape-morphing phenomena by combining photothermal shape-transformable polymer films and patterned inactive layers. Various reversible 3D shapes, including a complex human face and gripping-force-tunable soft grippers, can be fabricated with tunable deformation degree and rate. The shape transformations are achieved through simple peeling off and repatterning of black-tape strip layers, providing guidance for fabricating new soft robotics and biomimetic systems without intricate heterogeneity design in material properties.
