Multi-responsive actuators based on a graphene oxide composite: intelligent robot and bioinspired applications

Abstract: Carbon-based electrothermal or photothermal actuators have attracted intense attention recently. They can directly convert electrical or light energy into thermal energy and exhibit obvious deformations. However, if the actuation mechanism is only limited to thermal expansion, the deformation amplitude is difficult to increase further. Moreover, complex shape-deformation is still challenging. Although a few materials were reported to realize twisting or untwisting actuation by cutting the samples into strips a… Show more

“…Besides LCN‐based photoactuators, there exists another type of attractive photoactuator, mainly composed of nanocarbon (e.g., carbon nanotube (CNT) or graphene (RGO)) and polymer composite, which generates deformation owing to the photothermal conversion of nanocarbon and thermal expansion of polymer composite. These nanocarbon‐based photothermal actuators possess advantages of easy fabrication, multiform deformation, and operation through a convenient light source including white light or even sunlight, which show promise in the development of self‐oscillating autonomous actuators and related devices 43–51. For example, Yu et al report visible‐light‐driven graphene oxide/polymer nanocomposites exhibiting a unique tumbler type of movement 51.…”

“…In recent years, the demand for smart actuators based on flexible intelligent driving materials has increased [1][2][3][4]. The role of flexible intelligent driving materials is to convert external stimuli (such as light, heat, humidity, magnetic field/electric field) into executable actions or signals needed by processors through rapid, reversible and controllable structural/morphological changes [5][6][7][8][9][10][11][12][13][14][15][16]. Flexible smart actuators driven by these stimuli have significant advantages in the soft robot, electronic skin, bionic technology and other fields [17][18][19][20].…”

“…New materials with embodied functionality capable of actuation provide essential potential for further developing soft robotic systems such as light‐driven systems that enabling not only untethering but also drastically reducing complexity by providing integrated functionality. Many photochemical and photothermal reactions in functional materials enable actuation such as in liquid crystal polymers, in hydrogels and bilayered polymers filled with nanomaterials, in shape‐memory polymers, as well as nickel‐hydroxide‐oxyhydroxide‐based composites . Due to specific constraints of the underlying reaction, these materials may be restricted to certain environments or perform efficiently only at the microscale.…”
