Abstract
An ion-conducting layer for an actuator element including (I) a fluorine-containing polymer having a functional group and (II) an ionic liquid. The functional group is selected from —OH, —COOH, —COOR, —CN, iodine atom, epoxy group and (meth)acryloyl group, and is contained in a side chain and/or at an end of a trunk chain of the fluorine-containing polymer. Also disclosed is an electrode layer including (I) the fluorine-containing polymer having a functional group, (II) an ionic liquid and (III) an electroconductive nano-filler. Also disclosed is an actuator element including the ion-conducting layer and at least two electrode layers formed on the surfaces of the ion-conducting layer and insulated from one another, in which flection or deformation can be caused by applying an electric potential between the electrode layers.
