Abstract

An object of this invention is to create an actuator in which the amount of deformation is maintained and no displacement in the reverse direction occurs, even when a constant voltage is continuously applied for a long period of time. As a means for achieving the above object, the invention provides a conductive thin film comprising a polymer gel containing at least one organic molecule selected from the group consisting of electron-donating organic molecules and electron-withdrawing organic molecules, a nano-carbon material, an ionic liquid, and a polymer.

Dependent claims

A laminate comprising:

one or more conductive thin films and,
one or more electrolyte membranes including an ionic liquid and a polymer,
wherein each of the one or more conductive thin films comprises a homogeneous mixture comprising 5-90% by weight of a nano-carbon material, 5-80% by weight of an ionic liquid, 4-70% by weight of a polymer, and an organic molecule component comprising at least one electron-withdrawing organic molecule selected from the group consisting of chloranil, bromanil, and pyromellitic dianhydride (PMDA),
wherein the organic molecule component is present in an amount of 20 to 100 parts by weight per 50 parts by weight of the nano-carbon material, and
wherein the homogeneous mixture forms a gel.
