제목 Anion-conducting ionic polymer actuator for efficient force generator
초록 Ionic polymer actuator based on anion-conducting methylated PBI–OO membranes and a carbon composite electrode material was successfully developed. The methylated PBI–OO membranes exhibited high tensile moduli and strengths in the hydrated states due to the π–π stacking interaction among the benzimidazole rings in the polymer backbone. The actuators based on PBI–OO bent toward the negatively charged electrode direction reverse to the bending direction of conventional ionic polymer actuators with cation-conducting membranes. They also revealed exceptional charge-specific blocking forces because of a combinatorial effect of the larger modulus of PBI–OO-based actuators, the smaller size of ion clusters inside the PBI–OO layer, and the electrolysis of water restrained using a carbon electrode as well. Moreover, the actuators showed no back relaxation within the examined time period even under a high dc voltage beyond the electrolysis voltage of water.
