Unusual switching of ionic conductivity in ionogels enabled by water‐induced phase separation

Abstract Developing smart iontronic materials is highly desired for eradicating the widely occurring potential short‐circuit hazard and subsequent safety problems caused by high ambient humidity. In this work, a humidity‐responsive ionogel (HRIG) based on a poly(benzyl methacrylate) matrix swollen by hydrophobic ionic liquid and hygroscopic lithium salt is reported. The HRIG exhibits an anomalous decrease in ionic conductivity upon hydration …
