REACTIVE IONIC LIQUID AND ION-IMMOBILIZED METAL OXIDE PARTICLES PRODUCED USING SAME, ION-IMMOBILIZED ELASTOMER, AND TRANSDUCER

摘要

Provided is a reactive ionic liquid. The reactive ionic liquid can act as an ionic component which can be contained in an ion-containing layer that is formed in contact with a high-resistance layer that serves as a dielectric layer in a transducer, and does not migrate into the high-resistance layer upon the application of a voltage. The reactive ionic liquid comprises an ion pair of an anionic component and a cationic component, wherein (a) the cationic component is (a1) an imidazolium cation or a quaternary ammonium cation and is (a2) a cationic component having an alkoxysilyl group or a phosphonate group as a reactive group, and (b) the anionic component is (b1) a sulfonate anion, a sulfonylimide anion or a nitrobenzoic acid anion.
