제목 Self-assembled Sulfonated Block Copolymers Comprising Ionic Liquids for High Performance Electro-active Actuators
초록 Electro-active actuators composed of ILs have been extensively studied for biomimetic applications such as artificial muscles and robotics. Key issues in the development of the electro-active actuators are the achievement of fast switching time and low driving voltage, which are yet challenging for many proposed systems. In present study, we are motivated to solve the issues by employing phase-separated block copolymers as an electrolyte layer. Particularly, by incorporating a range of ILs comprising different heterocyclic diazoles and counter ions, we were able to control the morphology of the electrolytes, which is found out to impact the actuator performance. An in-depth study on the ion migration behavior of the IL-containing block copolymer electrolytes at a given electric field were carried out by combining in-situ SAXS and impedance spectroscopy experiments.
