Reinforcement in technological applications, hybrid materials gained a lot of interest. Nowadays, much attention is being paid on ionic liquid‐based hybrid materials due to exceptional properties of ionic liquids including thermal stability, non‐flammability, and insignificant vapor pressure combined with varied electrochemical stability window and high ionic conductivity. Ionic liquid‐based hybrid materials that are ionogels with special emphasis on polymer‐based ionogels are mainly emphasized in this review article. These hybrid systems are held together by a combined effect of numerous possible intermolecular interactions including electrostatic, Vander Waals, solvophobic, structural, steric, and hydrogen bonding. Therefore the complex chemo‐mechanical interaction between the polymer network and the ionic liquid may induce remarkable properties to design ionogels for versatile applications. Moreover, to further enhance the compatibility of IL with polymers, nanofillers are being used which may play a role as compatibilzer or as plastisizer to overcome the plastisizing effect of IL. In the last section, impact of addition of various nanofillers (carbon and metal/ metal oxide) on the stability of polymer ionogels is being reviewed with the examples quoted from literature. POLYM.
