(411j) Constructing Phase Separation in Ionogels: Strategies, Functions and Applications

Ionogels, which combine distinctive attributes from both ionic liquids and polymers, represent a promising class of soft materials that have found diverse applications in stretchable sensors, flexible electrodes, electroluminescence devices, and supercapacitors. The introduction of phase separation into ionogels provides additional flexibility in designing complex structures and implementing unique characteristics, thereby opening up new avenues for innovation.

Our research group has been focused on precisely controlling the phase separation dynamics of ionogels and exploring their potential applications. We have developed new strategies for dynamically regulating the reversible transformation of phase separation, resulting in ionogels with stimuli-responsive characteristics such as mechanical stiffening triggered by environmentally benign triggers like water and temperature. Meanwhile, we have investigated the potential applications of ionogels in areas such as flexible ionotronics, smart protection and underwater adhesive materials.
