Ionic liquid-based polymer nanocomposites for sensors, energy, biomedicine and environmental applications:Roadmap to the future

Current interest towards ionic liquids (ILs) stems from some of their novel characteristics, like low vapour pressure, thermal stability and non-flammability, integrated through high ionic conductivity and broad range of electrochemical strength. Nowadays, ionic liquids represent a new category of chemical-based compounds for developing superior and multifunctional substances with potential in several fields. ILs can be used in solvents such as salt electrolyte and additional materials. By adding functional physiochemical characteristics, a variety of IL-based electrolytes can also be used for energy storage purposes. We hope that the present review will supply guidance for future research focused on IL-based polymer nanocomposites electrolytes for sensors, high performance, biomedicine, and environmental applications.Additionally, we provide in this review a comprehensive overview about the polymer-based composites' ILs components, including a classification of the types of polymer matrix available. More focus is placed upon ILs-based polymeric nanocomposites used in multiple applications such as electrochemical biosensors, energy-related materials, biomedicine, actuators, environmental, and the aviation and aerospace industries. At last, we discuss existing challenges and prospects in this field and provide concluding remarks.
