Summary
The development of nanofluids in the last 20 years led to many attempts to apply efficiently the discovered enhancements in thermal conductivity caused by the presence of nanoparticles in the common heat transfer liquids, from low to moderate temperatures. However, the need to obtain data for several systems led the authors to many artificial conclusions that differ from laboratory to laboratory and, sometimes, in the same laboratory. \n\nThe main problems are the preparation of the nanofluids, the characterization of the nanomaterials particles employed, and the instrumentation used to measure thermal conductivity. In addition, the understanding of the structure of nanofluid, namely the interaction of the nanoparticle with the bulk base fluid is fundamental, the interface size (extension in space), as the most significant theories of heat transfer in nanofluids are strongly dependent on it.\n\nIonic Liquids have proved to be a very promising type of base fluids, due to their specific interactions with the nanoparticles/nanotubes. Our efforts in studying these nanofluids led to several conclusions that make IoNanofluids a very sustainable type of heat transfer agents, namely for solar applications.\n\nIt is the purpose of this paper to analyse the current status of our knowledge of IoNanofluids preparation, behaviour and properties, with specially emphasis in the heteromolecular interactions and its influence on the thermal conductivity of nanofluids. A detailed analysis of the most adequate methods for the measurement of this property in nanofluids will also be presented.
