Ionic electroactive polymer-based actuators have attracted much attention due to their low potential stimuli. In this work, MXene-Nafion composite actuators were fabricated, and the actuation performances were tested. The morphology of the as-made MXene-Nafion composite showed that the composite membrane was homogeneous, with an MXene doping level up to 5 wt%. In addition, the results of blocked force, response speed, and durability demonstrated that the actuation behavior of the composite-based actuator was enhanced due to the efficient dispersion of the two-dimensional nanofiller MXene. In addition, the blocking force of the composite actuator with a doping level of 0.5 wt% was about 6 times that of the pure Nafion without back-relaxation and durability degradation during the testing period.
基于离子电活性聚合物的致动器因其低电位刺激而备受关注。在这项工作中，制备了MXene-全氟磺酸复合致动器，并测试了其驱动性能。所制备的MXene-全氟磺酸复合材料的形态表明，复合膜是均匀的，MXene掺杂水平高达5 wt%。此外，阻塞力、响应速度和耐久性的测试结果表明，由于二维纳米填料MXene的有效分散，基于复合材料的致动器的驱动行为得到了增强。此外，掺杂水平为0.5 wt%的复合致动器的阻塞力约为纯全氟磺酸的6倍，在测试期间没有后松弛和耐久性下降。
