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.

Actuator element using carbon electrode

A conductive thin film is composed of a polymer gel including carbon nanotubes, an ionic liquid, and a polymer. At least one selected from the group consisting of fat and oil and a water repellent is included in the polymer gel or in a surface of the polymer gel.

Actuator element including fat and oil or water repellent

An electroconductive film for an actuator is formed from a gel composition including carbon nanofibers, an ionic liquid, and a polymer. The carbon nanofibers are produced with an aromatic mesophase pitch by melt spinning.

Carbon nanofiber actuator

A polymer actuator element includes an electrolyte layer and electrode layers, in which the electrode layer includes an activated carbon nanofiber and a carbon nanohorn.

Polymer actuator element

A method for producing an aggregated thread structure includes (a) a process of dispersing carbon nanotube to a first solvent, which is water or a mixed solvent containing organic solvent and water, with a surfactant, to create a dispersion and (b) a process of injecting the dispersion, in which carbon nanotube is dispersed, to a condensing liquid, which is a second solvent that differs from the first solvent, to thereby aggregate and spin carbon nanotube. The aggregated thread structure containing carbon nanotube has: a bulk density of 0.5 g/cmor more; a weight reduction rate up to 450&#xb0; C. of 50% or less; a G/D ratio for resonance Raman scattering measurement of 10 or more; and an electric conductivity of 50 S/cm or more.
