Either as salts or room temperature ionic liquids, fluorinated anion-based electrolytes have been a common choice for ionic electroactive polymer actuators, both linear and bending. In the present work, propylene carbonate solutions of four electrolytes of the three hugely popular anions-triflouromethanesulfonate, bis(trifluoromethane)sulfonimide, and hexafluorophosphate were compared and evaluated in polypyrrole linear actuators. The actuation direction, the characteristics-performance relations influence the behavior of the actuators. Isotonic Electro-chemo-mechanical deformation (ECMD) measurements were performed to study the response of the PPy/DBS samples. The highest strain for pristine PPy/DBS linear actuators was found in range of 21% for LiTFSI, while TBAPF had the least cation involvement, suggesting the potential for application in durable and controllable actuators. Interesting cation effects on the actuation of the same anions (CFSO) were also observed.
无论是作为盐还是室温离子液体，基于氟化阴离子的电解质一直是线性和弯曲型离子电活性聚合物致动器的常见选择。在本工作中，对三种非常流行的阴离子（三氟甲磺酸根、双（三氟甲烷）磺酰亚胺和六氟磷酸根）的四种电解质在聚吡咯线性致动器中的碳酸丙烯酯溶液进行了比较和评估。致动方向、特性-性能关系会影响致动器的行为。进行了等渗电化学机械变形（ECMD）测量以研究PPy/DBS样品的响应。对于原始PPy/DBS线性致动器，发现LiTFSI的最高应变在21%范围内，而TBAPF的阳离子参与最少，这表明其在耐用且可控的致动器中的应用潜力。还观察到了有趣的阳离子对相同阴离子（CFSO）致动的影响。
