| Outline of Final Research Achievements |
In this project, we used a base polymer derived from DNA for the polymer of nanocarbon polymer (NCP) actuators in order to stabilize the actuation and suppress the back-relaxation of NCP actuators. Furthermore, some of metals and organic molecules are intercalated into the DNA. By utilizing this interesting feature, we studied sensing response of the electrode films for the NCP actuators. As for the actuation response, we needed to add ionic liquid with DNA polymer to observe the actuation. It is also found that the back-relaxation of NCP actuators is improved by using DNA polymer. For example, the back-relaxation was not seen during applying a DC voltage (2.0 V) for 2 hours. As for the sensing response, we investigated the redox current peak based on the intercalation of DNA intercalator into the electrode films of NCP actuators by a cyclic voltammetry. For example, we succeeded to observe the current change due to the intercalation of ethidium bromide in the voltammogram.
