Summary
Most of the applications of ionic liquids (ILs) are related with chemistry and chemical engineering. Material properties (heat capacity, thermal conductivity, viscosity and other thermophysical properties) play an important role in the applications. These properties can be obtained by molecular simulation, prediction/estimation methods and by measurements. However, the number of combinations of cations and anions is immense. Being “target oriented” or “duty oriented” materials, the flexibility of their properties needs not only experimental measurements (very limited and time consuming), but theoretical developments and computer simulation, in order to develop sustainable and useful tools for project design, as it has been done by us in the past for molecular liquids [1-3]. \n\nDue to our current understanding at a nano dimension, the existing intermolecular forces and the supporting theories, it was not possible up to today to have a molecular based theory for the thermal conductivity of ionic liquids. Even the application of estimation techniques has proved to have a limited applicability. An IoNanofluid is defined as a stable dispersion of the nanomaterial in an ionic liquid. Ionanofluids are one of the most promising applications of ionic liquids in the area of heat transfer. All the models developed to model the thermal conductivity of nanofluids, assume on one and that the thermal conductivity of the ionic liquid is known (?), and no effort to take into account the molecular structure of the ionic liquid has been developed with success, although molecular dynamics based simulations that involve this structure and the special type of interaction with the nanomaterial, permiting us to start to understand this complex problem [4-6].\nIt is the purpose of this paper to give an update of the situation in the calculation of the thermal conductivity of ionic liquids and IoNanofluids.
