Abstract
Utilizing a two-step method, in this study prepared MWCNT-based nanofluids with and without Sodium dodecyl sulfate (SDS) surfactant at concentrations of 0.01, 0.03, and 0.05%. The incorporation of SDS significantly reduced sedimentation, enhanced stability as shown by UV-visible spectroscopy. After 720 hours, sedimentation rates in 0.03% nanofluids were similar regardless of surfactant use, while at 0.01 and 0.02% concentrations, those with surfactants sedimented more slowly than those without. These findings suggest that surfactant addition could be a valuable strategy for optimizing the performance of nanofluid-based applications.
