Eutectogels are ionic soft materials based on DES. They exhibit key properties (ionic conductivity, mechanical, and rheological properties) and additional material functionalities (selfhealing, stretchability, and pH-responsiveness), which are close to those of traditional ionic liquid based iongels.

However, in terms of fabrication and when compared to ionic liquids, DES have advantages that make eutectogels attractive for application in fields where the preparation of high-performance and low-cost iongels is critical, such as energy, bioelectronics and environment.
