Abstract

MXene (Ti₃C₂Tx) is known for its excellent hydrophilicity, electrical conductivity, and dispersibility. It is a promising candidate for the fabrication of moisture-responsive actuators due to the strong interaction between MXene sheets and water molecules. Inspired by natural organisms, a variety of moisture-actuated soft robots have been successfully developed through the systematic integration of MXene-based actuators. This minireview summarizes recent advances in the preparation and applications of MXene-based moisture-responsive actuators. The hydrophilic properties of MXene, along with design principles, working mechanisms, current progress, and applications of MXene-based actuators, are discussed. The future prospects and developmental directions of MXene-based moisture-responsive actuators are put forward, providing novel insights for their further advancement in the realm of automatable smart devices.
