Ionic Liquids in Nanofluids: Design and Applications

Abstract

The prospective element in the layout of nanofluids for advanced applications, ionic liquids (ILs), is distinguished through their distinct physicochemical attributes, which include strong ionic conductivity, excellent thermal stability, and minimal vapour pressure. Ionic liquid-based nanofluids (IL nanofluids) are produced when nanoparticles are added to ILs. These fluids have improved thermophysical and electrochemical characteristics over their base fluids. The relationship among ILs and nanoparticles has revealed enormous possibilities in thermal transfer systems as a whole storage of energy, and electrochemical equipment. IL nanofluids offer exceptional thermal conductivity (TC), viscoelastic control, and specific thermal capacity, which render them adequate for transferring heat fluids in solar energy production systems and other heat devices. Furthermore, their capacity to keep durability under elevated pressures and temperatures significantly boosts its applicability in severe conditions. Due to the relationship between the particles and the IL matrices, IL nanofluids have enhanced ionic conductivity, diffusion parameters, and proton-transfer capacities in electrochemical purposes. Batteries, fuel cells, sensors, and solar systems have all successfully made use of these characteristics. The design of IL nanofluids involves careful consideration of nanoparticle concentration, size, and surface functionalisation to optimise performance while mitigating challenges such as increased viscosity or agglomeration. Advances in synthesis techniques and characterisation methods have enabled the precise tailoring of these hybrid systems for specific applications. It is now possible to precisely customise these hybrid systems for particular purposes due to developments in synthesis and characterisation techniques. The subsequent research will focus on developing new nanoparticle-IL compositions for future technology platforms and enhancing the sustainability of IL nanofluids. The revolutionary importance of IL nanofluids in contemporary research and development is highlighted in this review, along with their potential to completely alter storing energy and heat transport technologies.
