Research Abstract |
In order to improve the actuation properties of nanocarbon polymer actuators, which consist of SWCNT, ionic liquids, and a base polymer, we investigated the influence of incorporation of conductive nanoparticles such as polyaniline into the electrode layer of the actuators. It was found that the strain was improved about 3 times larger than that of the actuator without any additives (the control). Moreover, the bending force was increased about 10 times larger than the control. The nanocarbon polymer actuators show the back-relaxation of displacement against DC voltage. From the view point of actuation mechanism, it was revealed that the back-relaxation is induced by the charging or discharging of anion of ionic liquid. It was also found that the addition of TCNQ or TTF-TCNQ complex into the electrode layer of the actuator improved the durability of actuation against DC-voltage. For example, the actuator with TCNQ did not show the back-relaxation for more than 2 hours.
