The actuators comprise cation-conducting block copolymers that exhibited a response time of tens of milliseconds and millimeter-scale displacement under 1 V in air, which has not been achieved by any actuators thus far. The important factor in its success involves the selective introduction of zwitterions into the nanoscale ionic domains of the polymer layer, which do not migrate under an electric field owing to the electro-neutrality. These zwitterions were designed to have structural resemblance to the polymer matrix and provide a polar medium with an exceptionally high dielectric constant of 76, thus facilitating ion dissociation and increased ion diffusivity. Accordingly, the ionic conductivities of the zwitterion-containing polymers increased 300-fold, while the single-ion conducting characteristics were preserved. We believe that these findings could enable the development of new soft actuators that can be used in the production of next-generation artificial muscles. ■お問い合わせ先 分子システムデバイス国際リーダー教育センター支援室 E-mail：office[at]molecular-device.kyushu-u.ac.jp TEL：092-802-2911 FAX：092-802-2912 〒819-0395 福岡県福岡市西区元岡 744 九州大学伊都キャンパス ウエスト 2 号館 627 号室 ■ 主催：九州大学 大学院博士課程教育リーディングプログラム 分子システムデバイスコース 事前登録はこちらから
