We synthesized the polyurethane elastomer like a polymer gel material without polar solvents. Since PUE films have been found to exhibit an electrostriction effect, we propose the applying them to a moving device such as an actuator similar to muscles. The actuators are of monomorph type fabricated by PUE film and metal electrodes evaporated at different thickness on the film surfaces. Because these actuators work at a high voltage more than lkV, we controlled the molecular structure of the films by doping C6o derivative (fullerenol) or CNT derivatives into PUE so that the actuators could operate under a low voltage. The bends of C6o and CNTdoped actuators were larger than that of non-doped actuators, and the working voltage became low. The force of the actuators increased in proportion to the electric field, and strongly depended on the thickness of the PUE films. Furthermore, in order to clarify the relationship between the stretch of PUE film and the bending mechanism of actuators, we measured the space charge in various kinds of PUE films using the pulsed electroacoustic method.
