dc.description.abstract | The stability along with thermal and rheological characteristics of ionanofluids (INFs) profoundly depend on the
protocol of preparation. Therefore, in this work, the effect of ultrasonication time on microstructure, thermal
conductivity, and viscosity of INFs containing 0.2 wt% of originally ultra-long multi-walled carbon nanotubes
(MWCNTs) and four different ILs, namely 1-propyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide, 1-
butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide, 1-ethyl-3-methylimidazolium thiocyanate, or 1-
ethyl-3-methylimidazolium tricyanomethanide, was studied. The INFs were obtained by a two-step method using
an ultrasonic probe. The ultrasonication process was performed for 1, 3, 10, or 30 min at a constant nominal
power value of 200 W. The obtained results showed that for the shortest sonication time, the highest thermal
conductivity enhancement of 12% was obtained. The extended sonication time from 1 to 30 min caused the
cutting of MWCNTs and breaking the nanoparticle clusters, leading to a decrease in the average length of the
nanotube bundles by approx. 70%. This resulted in a decline in thermal conductivity even by 7.2% and small
deviations from the Newtonian behavior of INFs. | pl_PL |
