There is growing interest in blending polymers and ionic liquids (ILs) as a simple route to obtain solid-state ion conductors for a wide variety of electrochemical devices such as fuel cells and actuators. In this work, we present fascinating experimental insights into confinement- and interface-driven modulation of ion transport properties and bending motion of IL-containing polymer electrolytes by varying the type of ILs. The new actuator demonstrated improvements in actuation properties over other polymer actuators reported earlier, large generated strain (up to 4%) without any signs of back relaxation. In particular, the millimeter-scale displacements obtained for the actuators, with rapid response (＜1 s) at sub-1-V conditions over 13500 cycles in air, have not been previously reported in the literature. This work suggests the future prospects for designing desired nanostructures as efficient ion conductors. |
