Stable Operation and Training Effect in Electrochemomechanical Deformation using Conducting Polymers and Ionic Liquids

导电聚合物中的电化学机械变形(ECMD)因其应变大、作用力大、操作安静等特点，在驱动机器人方面备受关注。然而，实际应用需要长周期的稳定性。用离子液体证明了聚吡咯在ECMD中的长周期稳定性，并阐明了其机理。聚乙二氧基噻吩膜即使在盐水中也能稳定运行。此外，还发现聚苯胺在拉应力作用下表现出训练效应。

Electrochemomechanical deformation(ECMD) in conducting polymers is interested in driving of robots, because of the large strain, force and quiet operation. However, the long cycle stability is required for the practical application. The long cycle stability in ECMD of polypyrrole was demonstrated by using ionic liquids, and the mechanism was clarified. Poly(ethylenedioxythiophene) exhibited stable operation even in saline water. Furthermore, polyaniline is found to show a training effect under operation of tensile stresses.
