| Popis: | The actuation mechanism of dry-type polymer actuators composed by single-walled carbon nanotubes, an ionic liquid, and a base polymer (named as nanocarbon polymer (NCP) actuators) was studied. NCP actuators have a three-layered structure, that is, an electrolyte layer is laminated by two electrode layers. NCP actuators initially show a bending motion toward the anode side but show a reverse bending motion over time in the lower frequency ranges of applied voltage or at the DC voltage. In order to clarify the actuation mechanism, we investigated the actuation by changing the amount of ionic liquids and the species of ionic liquids in both the electrode layers and the electrolyte layer of actuators. It was found that the reverse bending motion was caused by the transport of anion. |
