ABSTRACT:
Polymeric systems are disclosed that exhibit the Johnsen-Rahbeck effect and an electrostatic clutch for using films of these polymeric systems. The films may be pressed from the polymeric reaction product of either a polymer having an anionic functionality reacted with cations, or a polymer having cationic functionality reacted with anions. The dielectric film may be interposed between nesting, or otherwise contacting, conductive surfaces to increase the frictional force between the surfaces by the Johnsen-Rahbeck effect when a voltage differential is applied across the surfaces.
