Abstract: The purpose of this study was to measure the thermodynamic properties of 1-hexyl-3-methylimidazolium tetrafluoroborate ([HMIM]BF4) and its graphene-dispersed ionic liquid based nanofluids (Ionanofluids) from room temperature to 200 °C. A thermal analyzer measured the thermal conductivity of the samples using the transient plane source (TPS) method. Results showed that the thermal conductivity of [HMIM]BF4 and the GE-dispersed Ionanofluids increased linearly with temperature, and with mass particle fraction. It was determined that GE was a more effective filler than other carbon and metal nanoparticles because the thermal conductivity of the [HMIM]BF4/GE solution was higher than commercial brands.
