Abstract
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.
Claims7
An actuator element comprising:
- an electrolyte membrane including a polymer and an ionic liquid;
- and
- at least two electroconductive films provided in a mutually insulative state on the opposing surfaces of the electrolyte membrane, wherein each electroconductive film is formed from a gel composition including carbon nanofibers, an ionic liquid, and a polymer, wherein the carbon nanofibers comprise a melt spun aromatic mesophase pitch, wherein the carbon nanofibers comprise activated carbon nanofibers,
- wherein the actuator deforms when a potential difference is applied across the electroconductive films.
