Imidazolium sulfonate-containing pentablock copolymer-ionic liquid membranes for electroactive actuators

Block copolymer-ionic liquid composite materials emerge as promising candidates for electromechanical transducer applications. Herein, a novel imidazolium sulfonate-containing pentablock copolymer-ionic liquid composite was prepared and fabricated into thermally stable electroactive actuators, which exhibit effective actuation response under a low applied potential of 4 V.
