“…[126] Li et al designed an electrothermal actuator with a Ti 3 C 2 T x MXene-CNT/PDMS bilayer film through vacuum-assisted filtration and hot pressing. [127] Under electrical stimulation, the MXene-CNT layer's low sheet resistance allows for the efficient conversion of electric energy into thermal energy as per the Joule heating system's electric power formula. The thermal energy accomplishes two key actions: first, it separates the water molecules bonded to the surface of the MXene-CNT layer through hydrogen bonds associated with the oxygencontaining functional groups; second, it induces expansion in the PDMS layer.…”

“…For instance, a flexible, hydrophobic, mechanically robust, and electromagnetic interference shielding the soft electrothermal actuator based on polytetrafluorethylene (PTFE)/MXene/PI is easily assembled using a simple “cutting and sticking” technique, where PI and PTFE tapes are applied to the surface of the MXene film [125] . Furthermore, as a result of the enhanced electrical conductivity of MXene composites (such as MXene/graphene, [36] MXene/Ag, [126] and MXene‐CNT [127] ), the MXene‐based actuators exhibited excellent electrothermal properties. Bimorph actuation layers were created by combining a cellulose paper with a polyimide tape, incorporating an MXene/graphene bilayer to provide electrothermal functionality and electrical signal feedback [36] .…”

Compared with traditional rigid actuators, soft actuators exhibit a large number of advantages, including enhanced flexibility, reconfigurability, and adaptability, which motivate us to develop artificial soft actuators with widespread applications. Soft actuators with MXene nanomaterials are regarded as highly promising candidates for advancing the development of bioinspired soft robotics as a consequence of their unprecedented physicochemical characteristics, such as high electronic conductivity, thermal conductivity, photothermal conversion capability, and abundant surface functional groups. Herein, a comprehensive overview of the recent advancement of soft actuators with MXene nanomaterials and their extensive applications from the perspective of bioinspiration is provided. First, synthetic methods of MXene and their properties are briefly summarized. Subsequently, soft actuators with MXene nanomaterials (including photoresponsive soft actuators, electroresponsive soft actuators, and chemoresponsive soft actuators) are sequentially investigated with a focus on the fabrication approaches, actuation properties, underlying mechanisms, and promising applications. At the end, the future challenges and opportunities for the rapid development of soft actuators with MXene nanomaterials are discussed.

“…Polydimethylsiloxane (PDMS), as a transparent adhesive and elastomer, is widely used for integrating raw materials with different properties in one single system due to its excellent compatibility, hydrophobicity, and high flexibility. [47,48] Thus, it is anticipated that the actuators which incorporate the inherent characteristics of SA, Fe 3 O 4 and PDMS would competently implement the multi-stimulus actuations. under magnetism, sunlight, and humidity.…”

Soft actuators can harvest environmental energy and convert it into kinetic energy for motions like bending, twisting, stretching, and contracting. However, it remains challenging to design soft film actuators for complex and programmable deformation in three dimensions. Herein, a weldable and patternable multi‐stimuli‐responsive bilayer soft actuator is developed by a mask‐assisted spraying coating process, and its 3D geometries are achieved by welding the sodium alginate (SA) layer using water. The intrinsic hygroscopicity of SA film and the magnetic and photothermal properties of Fe3O4 nanoparticles enable reversible deformation of the bilayer actuator under three different external stimuli: moisture, magnetic field, and sunlight. Based on these properties, a variety of multi‐stimuli‐responsive intelligent devices are developed including smart curtains, smart grippers, biomimetic walkers, rolling actuators, swimmers, and windmill rotators. All these actuating stimulations are derived from naturally renewable energy without the consumption of any artificial energy, providing important enlightenment for green and sustainable applications of soft actuators.
