Graphene is considered a promising substance in applications related to the capture and\nreduction of the environmental impact of fluorinated gases. However, further research is still required\nto explore all related possibilities. In this work, the potential use in this context of nanofluids (NFs),\nobtained by dispersing graphene nanosheets in fluorinated ionic liquids (FILs) is investigated. As a\nstarting step, a thermal and structural characterization for this type of IoNanofluids (IoNFs) is\npresented. The highly nanostructured nature of FILs has been recently demonstrated. The presence\nof fluorinated moieties is responsible for enhancing the accommodation of solutes such as small gases.\nThe strong tendency to self-assemble forming continuous and supramolecular structures, and the\nversatility to rearrange in several conformational features allows the stabilization of nano colloidal\nsystems. It is essential to perform a comprehensive study of their structural features to understand\nthe behavior of this type of heterogeneous systems. Therefore, we present screening on the phase\nand structural behavior of these novel IoNFs to discover and develop optimized systems where FILs\nturn out to be advantageous. Thermogravimetric analysis (TGA) was employed to evaluate IoNFs\nmass losses with temperature, and their solidâ??fluid phase transitions were located using a differential\nscanning calorimeter (DSC). Their rheological properties were also determined through oscillatory\nexperiments, obtaining the viscous and loss moduli. In addition, the structural percolation transition\nwas also identified.
