Polymer actuator element
View Patent ↗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.
1. A polymer actuator element comprising:
an electrolyte layer; and
an electrode layer formed on a surface of the electrolyte layer,
wherein the electrode layer includes:
an activated carbon nanofiber; and
a carbon nanohorn,
wherein a weight ratio of the carbon nanohorn in the electrode layer is greater than that of the activated carbon nanofiber.
2. The polymer actuator element according to claim 1 ,
wherein the activated carbon nanofiber is formed from an aromatic mesophase pitch by a melt-spinning method.
3. The polymer actuator element according to claim 1 ,
wherein the weight ratio the carbon nanohorn with respect to a total carbon content of the electrode layer is in a range of 0.5 to 0.7, exclusive of 0.5.
4. The polymer actuator element according to claim 1 ,
wherein the electrode layer further includes ionic liquid, and a weight ratio of the ionic liquid with respect to a total carbon content in the electrode layer is in a range of 1.3 to 1.7.
5. The polymer actuator element according to claim 1 ,
wherein the electrode layer further includes a base polymer, and
a weight ratio of the base polymer with respect to a total carbon content in the electrode layer is in a range of 0.7 to 1.1.
6. The polymer actuator element according to claim 3 ,
wherein the electrode layer further includes:
ionic liquid having a weight ratio in a range of 1.3 to 1.7 with respect to the total carbon content in the electrode layer; and
a base polymer having a weight ratio in a range of 0.7 to 1.1 with respect to the total carbon content in the electrode layer.
