| Abstract | Room temperature ionic liquid-based nanofluids containing functionalized multi-walled carbon nanotubes(F-MWCNTs) were fabricated. Transmission electron microscopy (TEM), field emission scanning electronmicroscopy (FE-SEM), Fourier transform infrared (FT-IR), and X-ray photoelectron spectra revealed themorphology and chemical structure of the obtained F-MWCNTs. The rheological behaviors of the F-MWCNTs/1-butyl-3-methylimidazolium hexafluorophosphate ([Bmim][PF6]) nanofluids were studied, demonstrating theshear thinning behavior of nanofluids at rather low concentrations, which could be due to the high specificratio, flexibility of F-MWCNTs, and the formation of a transient network through nanotube nanotube andnanotube matrix interactions. It was found that the rheological behavior of the F-MWCNTs (0.1 wt %)/[Bmim][PF6] nanofluid was similar to that of the surfactant worm-like micelle systems. Therefore, the transientnetwork structure of the F-MWCNTs (0.1 wt %)/[Bmim][PF6] nanofluid could be renovated in a short timeafter shearing forces were input. The shear viscosity of the nanofluids was even lower than that of pure[Bmim][PF6], especially under high shear rates, which could be attributed to the self-lubrication of F-MWCNTs.The tribological properties of the nanofluids were also evaluated in comparison with those of pure [Bmim][PF6]under loads in the range of 200 800 N, indicating that the nanofluids exhibited preferable friction-reductionproperties under 800 N and remarkable antiwear properties with use of reasonable concentrations. |
