Dynamic Characteristics of Novel Ionic-Polymer-Metal-Composites
The IPMC, one of new sensing and actuating materials is known for the fast and flexible bending actuation upon electric fields. In this paper, we investigated the dynamic deformation characteristics of the novel IPMC according to several fabrication methods. First we studied the effect of the surface modification of metallic electrodes on the large deformation. Present results show that the sandblasting method can give more reliable and large deflections than the sandpapering method under the same control voltage because the platinum electrode can be infiltrated into the ionic-polymer by the sandblasting method. Second, the IPMC with Li+ counter ions shows more large deformation than that with any other counter ions. Also, present results show the dynamic hysteresis according to driving voltages.
