Actuator with ionic liquid

摘要

An actuator includes a pair of electrodes facing each other, an intermediate layer containing an ionic liquid and arranged between the pair of electrodes, the electrodes and the intermediate layer being deformed when a potential difference larger than a potential window of the ionic liquid is applied between the electrodes, and insulating layers that suppress direct contact between ions of the ionic liquid and the electrodes, the insulating layers being arranged between the intermediate layer and the electrodes.

1. An actuator comprising:
a pair of electrodes facing each other; an intermediate layer containing an ionic liquid and arranged between the pair of electrodes, the electrodes and the intermediate layer being bent and deformed when a potential difference larger than a potential window of the ionic liquid is applied between the electrodes; and insulating layers that suppress direct contact between ions of the ionic liquid and the electrodes, the insulating layers being arranged between the intermediate layer and the electrodes wherein the insulating layers contain an insulating polymer and highly dielectric inorganic particles; and wherein in the insulating layers, an amount of the highly dielectric inorganic particles may be 10% by weight or more and 90% by weight or less relative to an amount of the organic polymer.
