英文摘要 | Room temperature ionic liquid-based nanofluids containing functionalized multi-walled carbon nanotubes (f-mwcnts) were fabricated. transmission electron microscopy (tem), field emission scanning electron microscopy (fe-sem), fourier transform infrared (ft-ir), and x-ray photoelectron spectra revealed the morphology and chemical structure of the obtained f-mwcnts. the rheological behaviors of the f-mwcnts/1-butyl-3-methylimidazolium hexafluorophosphate ([bmim][pf(6)]) nanofluids were studied, demonstrating the shear thinning behavior of nanofluids at rather low concentrations, which could be due to the high specific ratio, flexibility of f-mwcnts, and the formation of a transient network through nanotube nanotube and nanotube matrix interactions. it was found that the rheological behavior of the f-mwcnts (0.1 wt %)/[bmim][pf(6)] nanofluid was similar to that of the surfactant worm-like micelle systems. therefore, the transient network structure of the f-mwcnts (0.1 wt %)/[bmim][pf(6)] nanofluid could be renovated in a short time after shearing forces were input. the shear viscosity of the nanofluids was even lower than that of pure [bmim][pf(6)], 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][pf(6)] under loads in the range of 200-800 n, indicating that the nanofluids exhibited preferable friction-reduction properties under 800 n and remarkable antiwear properties with use of reasonable concentrations. |
