MXene, renowned for its natural "quantum-confined-superfluidic" (QSF) channels, demonstrates superior electrical/thermal conductivity, favorable hydrophilicity, and remarkable mechanical strength, rendering it an ideal candidate multiresponsive actuators, which are promising soft electronics robots. Currently, most MXene-based actuators mainly prepared by combining active layer inner layer, with only a few utilizing regulated QSF channels. However, tailoring channels is extremely challenging. Herein, we introduce graphene oxide (GO)&Fe3O4/MXene actuator that can respond to humidity, light, heat, electricity, magnetic fields constructing asymmetric The water adsorption, transportation, desorption behaviors, controlled the different between GO&Fe3O4 MXene enable multiresponsiveness of actuator. As proof-of-concept demonstrations, several smart devices, such as bionic crab-like crawler, transporting flower robot, gripper, prepared, holding great potential advancing future robotics.
