N2 - Carbon Nanotube (CNT) is a material known to have a high thermal conductivity. Therefore, CNT is widely used for heat transfer applications. One of the CNT applications in heat transfer is to make nanofluids. CNT is a cylindrical molecule consisting layers of single layer carbon atom sheets (graphene). CNTs can be single walled (SWCNT) or multi-walled (MWCNT). In this study, MWCNT was used and characterized by using Scanning Electron Microscope (SEM). CNT-based nanofluids were synthesized by adding 0.01%, 0.03%, and 0.05% of CNT particles as well as 10%, 20%, and 30% Polyethylene Glycol (PEG) surfactants into distilled water. The objective of surfactants addition was to maintain the stability of nanofluids. The addition of PEG surfactant concentrations by 20% and 30% decreases the thermal conductivity of nanofluids. On the other hand, the stability of CNT-based nanofluids increases after the addition of PEG surfactants.
