Ion‐Exchange‐Driven Ternary Organic Neuromorphic Devices with High Efficiency and Stability
Advanced Science, EarlyView.Spontaneous ion exchange in a ternary polymer–ionic liquid blend disrupts the phase‐separated ionic domains of the binary film and creates a more homogeneous polymer–ion environment. This ionically reorganized matrix enables stable and efficient electrochemical doping, leading to ion‐gel‐gated organic electrochemical transistors with enhanced ...
