This approach allows the preparation of thermoreversible ionogels with high ionic conductivity (up to 60 mS cm(-1)), remarkable mechanical properties (storage moduli above 10(5) Pa a value comparable to the mechanical properties of some rubbers), and melting points in the range from -20 to 53 degrees C. These properties can be easily tuned in a broad range by varying the water (and/or inorganic salts) concentration in the ionogels. The described method is a very convenient way to prepare ionogels because it is based on simple and inexpensive materials, namely AMMOENG100 and water (no volatile organic solvents involved).
