Title: High performance IPMC Actuator based on novel 2D electrical-conductive MOF composites

Abstract:

Existing ionic artificial muscles still require a technological breakthrough for much faster response speed, higher bending strain, and longer durability. Here, we report an artificial muscle based on ionically cross-linked Zn-CAT with poly(3,4 ethylenedioxythiophene)-poly(styrenesulfonate), showing ultrafast rise time of within 1.5 s in DC responses, extremely large bending strain up to 1.22% in very low input voltage regime (0.1 to 3V), long-term cyclic stability of 97% up to 10,000 cycles, markedly reduced phase delay, and very broad frequency bandwidth up to 20 Hz with good structural reliability without delamination under continuous electrical stimuli. These successful demonstrations elucidate the wide potential of MXene-based soft actuators for the next-generation soft robotic devices, including wearable electronics and artificial muscles.
