US Patent 8004146 - CNT ionic actuator

http://www.freepatentsonline.com/8004146.html

This patent from the National Institute of Advanced Industrial Science and Technology in Japan teaches a way to form ionic actuators from carbon nanotube material without the use of a polymer which can lead to an improved response speed of actuation. Claim 1 reads:

1. An electrically conductive thin film formed from an ionic liquid and carbon nanotubes having an aspect ratio of not less than 10,000 and being free of polymer.
